High strength bonding of glass to glass, glass to metal, glass to ceramic or glass to plastic can be achieved with flat glass, float glass, tempered glass, and a myriad of other glass types. High strength bonding of glass to glass, or glass to metal, can be achieved with flat glass, float glass, tempered glass, and a myriad of other glass types.
A unique product has been developed to facilitate the creation of decorative glass used in windows, doors, mirrors, lighting, goblets, vases, and other household accessories.
Tangent Industry’s glass adhesive product line has given artists and entrepreneurs a new, exciting avenue of glass based construction. Examples at left are from McLemore Display Company’s line of glass shelving, display cases, and racks.
View the glass bonding adhesive selections listed below for a possible candidate for your application. Bevelling is the method by which a piece of glass is being bevelled on the edges of one of its sides. Regardless of the thickness of the glass or the size of the hole needed, the drilling is processed smoothly leaving a perfect finish on the glass.
We use this method to bond together two or more pieces of glass that eventually have very strong endurance but loose nothing from their transparency.
This is the production of a laminated type of glass that is consistent of three layers with the one being cracked. Double Glazing usually refers to two panes of glass enclosing a hermetically closed air space.

Klearia overcomes a major technological limitation by bonding at a low temperature between 100°C and 300°C. While each chemical element is made up of atoms, it is the difference in atomic structure that gives the element its characteristic properties. Protons are particles of positive electricity, electrons are particles of negative electricity and neutrons are particles without any electricity.
It is not possible to determine exact orbit of an electron but its position is determined by the probability that it will be found in a given region (state) of the atom.
Based on above, for each shell, number of subshells (energy levels) and number of electrons in each subshell can be tabulated as under. The letters s, p, d, f, g and h have been introduced to signify l = 0, 1, 2, 3, 4, 5, so that the energy level corresponding to n = 1 and l = 0 is called the 1s level, that corresponding to n = 2 and l = 0 is called 2s, that corresponding to n = 2 and l = 1 is called 2p level, etc. Based on above, distribution of electrons in different shells for iron (26 electrons) will be as shown below.
It may be noted that iron atom has first and second shell full, third shell partly filled with 14 electrons and fourth shell also partly filled with 2 electrons.
The chemical elements may be roughly classified into three groups, metals, metalloids and nonmetals. The metals are on the left side of periodic table and constitute about three-fourths of elements. At low temperatures the nuclei of the atoms of a solid vibrate about an equilibrium position but are trapped in their lattice positions, unable to flow or diffuse.
Gases consist of large numbers of molecules (or atoms, in the case of the noble gases) that are in continuous random motion. It is the characteristic of the solid state that all true solids exhibit a crystal structure which is a definite geometric arrangement of atoms or molecules. Atoms are at their most stable condition when they have no partially-filled electron shells. A common characteristic of metallic elements is that they contain only one to three electrons in the outer shell. A solid is one of the three states of a matter in which atoms are closely packed as compared to the other states, gas and liquid. Notice that once we begin stacking the unit cells, we never change the orientation of any subsequent unit cells as they stack.
As shown in above figure, the specific unit cell for each material is defined by its parameters, which are the edges of the unit cell a, b, c and the angles I± (between b and c), I? (between a and c) and I? (between a an b). There are only 14 possible types of space lattices, known as Bravais Lattices and fall into seven crystal systems as under. If the rows of atoms are packed in this third layer so that they do not lie over atoms in either the A or B layer, then the third layer is called C. A third common packing arrangement in metals, the body-centered cubic (BCC) unit cell has atoms at each of the eight corners of a cube plus one atom in the center of the cube. For comparison, all the three types of packing arrangements are shown together in the figure given below. During crystallization, if atoms are not packed as per required sequence of packing arrangement (say ABAB, ABCABC, etc.), it is called stacking fault. A body centered cubic cell has one atom in the centre of the cube and one atom each at all corners. A face centered cubic cell has an atom at each corner of the cube and in addition, one atom at the intersection of the diagonals of each of the six faces of the cube. The usual picture of the close packed hexagonal lattice shows two basal planes in the form of regular hexagons with an atom at each corner of the hexagon and one atom at the center.
Polymorphism is the property of a material to exist in more than one type of space lattice in the solid state. Miller indices is a system of notation that denotes the orientation of the faces of a crystal and the planes and directions of atoms within that crystal. A crystallographic plane is specified in terms of the length of its intercepts on the three axes. To designate Miller indices of a plane, one corner of a unit cell is assumed to be the origin of the space coordinates, and any set of planes is identified by the reciprocals of its intersection with these coordinates.
Note:As per convention, bar sign, A? shall be placed above k as shown above 1 in the figure given below to show plane ABGF. Determine the intercepts of the face along the crystallographic axes, in terms of unit cell dimensions.
Obtain Miller indices by clearing fractions and reducing them to lowest integer having the same ratio.
Braces signify a family of planes of the same a€?forma€? (which are equivalent in the crystal).
Family of cube faces of a cubic crystal can be shown as: {100} = (100) + (010) + (001) + (A?100) + (0A?10) + (00A?1). In the cubic system, planes having the same indices regardless of order or sign are equivalent. In crystallography, a direction is always perpendicular to the plane having the same indices.
Miller Bravais indices are used to specify planes and directions in the close packed hexagonal (cph) structure, giving four indices (hkil). Number of atoms per length whose centers lie on the direction vector for a specific crystallographic direction. For example, speed of sound depends on directions and slip (deformation in metals) depends on linear and planar density. However, most engineering materials consisting of many crystals and are known as polycrystalline materials. For many polycrystalline materials the grain orientations are random before any working (deformation) of the material is done.


As shown in the above figure if grains are randomly oriented properties will be identical in all directions (isotropic). From its inception over 15 years ago, Tangent Industries continues to develop new light curable adhesives and polymers that address the evolving challenges of glass assembly.
Full cure is achieved in seconds, which yields faster assembly time and lower process costs.
Distinctive patterns can be chipped into glass using Tangent Industries exclusive Chip-In-Place polymer. Please contact Tangent Industries to confirm your product selection and to secure additional application assistance, including samples and process recommendations.
When the bevels are exposed in the sunlight they become prisms, offering a spectrum of colours that highlight the glasswork. The glass is engraved by a technologically advanced computer-guided machine which ensures the accuracy of depth and angle along the surface of the glass. In this way, we produce various glass furniture of unique beauty such as tables, stands, desks, shelves etc. Variation in the thickness of the two glasses, their type and the thickness of the spacer between them, affects factors such as the degree of thermal insulation, soundproof and safety provided by the double glazing.
Low temperature bonding (?300°C) allows to integrate more materials for embedded technologies.
The maximum number of electrons in a given shell is 2n2, where n is the principal quantum number of the shell. The figure given below schematically shows some of the possible electron states in an atom and their energy levels. Third and fourth shells are partially full to satisfy position of a subshell based on their energy level. As shown in the figure given below, there are three states of matter a€“ solid, liquid and gas. Some materials, such as glass or tar, that are rigid at room temperature do not have a regular arrangement of molecules but rather the random distribution that is typical of the liquid state.
These positively charged metallic ions are held together by virtue of their mutual attraction for the negative electron cloud. When the atoms are brought close together there is a separation of the centers of positive and negative charges, and a weak attractive force results.
When the atoms or molecules in a solid are arranged in an irregular fashion, it is known as amorphous solid. In other words, once the orientation of a unit cell is determined, all unit cells within that lattice have the same orientation. Again rows of marbles will nest in the hollows between atoms in the second layer but two possibilities exist. This packing sequence would be designated ABCABC, and is also known as face-centered cubic (FCC) as shown in the figure given above. For explaining their construction in the figures given below, atom is represented as a point (center image) and more accurately as a sphere as they are actually in their lattice structure (left and right images).
Because each of the corner atoms is the corner of another cube, the corner atoms in each unit cell will be shared among eight unit cells. As the atom in the face is shared with the adjacent cell, FCC unit cells consist of a net total of four atoms, eight eighths (one) at the corners and six halves (three) in the faces. In addition there are three atoms in the form of a triangle midway between the two basal planes. If the change in structure is reversible, then the polymorphic change is known as allotropy.
It gives information in terms of crystallographic planes and directions with respect to three principal axes.
The layers of atoms or the planes along which atoms are arranged are known as atomic or crystallographic planes. Thus while (hkl) is used for a crystallographic plane, {hkl} is used to show family of crystallographic plans (hkl), (lhk), (hlk), etc. In order to arrive at a point on a given direction, consider that starting origin, it is necessary to move a distance u times the unit distance a along the X axis, v times the unit distance b along the Y axis, and w times the unit distance c along the Z axis. It can be seen in the figure given below that the direction FD, [110] is perpendicular to the plane BCGH, (110). Three axes a1, a2 and a3 are 120A° apart in the basal plane and the vertical c axis which is normal to the basal plane. Slip occurs on planes that have the greatest density of atoms in direction with highest density. For example, sometimes turbine blades are made from single crystal to improve high temperature mechanical properties. For example, as shown in the above figure the modulus of elasticity (E) in BCC iron is different in different directions. Therefore, even if the individual grains are anisotropic, the property differences tend to average out and, overall, the material is isotropic.
However, if grains are textured due to working (say rolling), properties will be different in different directions (anisotropic). Typical applications include glass lamination, signage, display cases, glass furniture, jewelry, affixing window latches, and cutting edge optical assemblies. The advantage of this polymer over other methods and materials is that Chip-In-Place is low odor, fast curing with UV light, and produces finished patterns in hours, not days!
In the event that these standard products do not satisfactorily address your performance requirements, Tangent will investigate other solutions that include development of adhesive specifically tailored to the complexity of your application.
We can obtain bevelling in both geometrical and abstract glass’s shapes due to our advanced machinery. The preparation of the designs and the sandblasting are both executed by computer-guided machines.
In addition, it has the capabilities of replicating designs on different glass sizes and, creating both mat and clear engravings, according to the customer’s preferences.
Furthermore, we can bond glass with metal (stainless steel) for those who enjoy mixing of materials in their space.
So, with its characteristics being both decoration and safety it can be put on windows, doors, it can be used as the top of a table or even as a floor.
Thus, Klearia is capable, besides ITO, Pt, Au and Cu, to integrate termodegradable materials like carbon, nanostructured gold, etc.
When atoms are brought together, they tend to arrange themselves in infinitesimal cubes, prisms, and other symmetrical shapes. The solution of the wave equation leads to four quantities known as the quantum numbers n, l, ml and ms. Thus in K shell (n=1) there is only one subshell (n=1), in L shell (n=2) there are two subshells (n=2) and so on.
Covalent bonds are called directional because the atoms tend to remain in fixed positions with respect to each other. Since the electrons are free to move, they lead to good thermal and electrical conductivity. It is of importance only at low temperatures when the weak attractive force can overcome the thermal agitation of the atoms. On the other hand, when atoms or molecules are arranged in some regular fashion, it is known as crystalline solid. The different colors are just to show the separate cells – each unit cell is identical.


If the rows of marbles are packed so they are directly over the first layer (A) then the arrangement could be described as ABA.
Both arrangements give the closest possible packing of spheres leaving only about a fourth of the available space empty. Thus the BCC unit cell consists of a net total of two atoms, the one in the center and eight eighths (equal to one) from the corners. If the basal plane is divided into six equilateral triangles, the additional three atoms are nestled in the center of alternate equilateral triangle. The plane ABGF now cuts the X axis at (-) 1 but is parallel to Y axis (DC) and Z axis (DE). If u, v and w are the smallest integers to accomplish the desired motion, they are the indices of the direction and are enclosed in square brackets [uvw].
We can say along closest packed directions on the closest packed planes (for detail, please refer article on plastic deformation and fracture). When a material is formed, the grains are usually distorted and elongated in one or more directions which make the material anisotropic. This eliminates long waiting periods, space-consuming racking, and the high cost of inventory. Our bevelled products can be decorated on windows, doors, tables, kitchen cabinets and walls.
This allows the etching of the glass with the accuracy of a millimetre and hence the creation of perfect designs. Engraving can be applied on any type of glass (float, laminated, painted, mirrors) and in combination with coloured, sandblasted or patterned glass for exquisite glass creations.
Lastly, our glass-metal products can be combined with wood for furniture that surprise with their finesse and stylishness. These geometrical units, joined to each other like perfectly fitted blocks make the larger structure known as crystals. Electrons are spinning on their axis and simultaneously around the nucleus at very high velocity. Of these, n is the principal quantum number related with the total energy of the electron in a particular state. Even amorphous solids have relatively good spatial ordering, especially over small distances (10-100 molecules).
One has a positive charge (it has more protons than electrons) and the other a negative charge. To become stable, the metal atom wants to get rid of one or more electrons in its outer shell and nonmetal atom wants to gain electrons. As shown above, nitrogen has 5 electrons in the outer shell and needs 3 electrons to complete shell.
When a solid has a crystalline structure, the atoms are arranged in repeating structures called unit cells, which are the smallest units that show the full symmetry of a crystal.
The marbles would be placed on the bottom of the box in neat orderly rows and then a second layer begun.
For example, in above figure, to determine the direction AC, starting at the origin (point A), it is necessary to move one unit along the X axis to point D and one unit in the direction of Y axis to reach point C. Considering the atoms at the lattice points, the number of atoms on a particular plane would be as under. The product is also available in gel viscosity which allows curved and vertical surfaces to be etched. We also process them in combination with patterned or coloured glasses to create interesting visual effects and interior designs. The diameter of the nucleus is of the order of 10-12 cm and is very small compared with the diameter of an atom which is approximately 10-8 cm (one angstroms). The metallic bond may be thought of as an extension of the covalent bond to a large number of atoms. The second layer of marbles cannot be placed directly on top of the other marbles and so the rows of marbles in this layer move into the spaces between marbles in the first layer.
This ABAB arrangement is called close packed hexagonal (CPH) as shown in the figure given below.
Examples of metals that crystallize in this type of structure are alpha (I±) iron, chromium, molybdenum, tungsten, vanadium, etc. Examples of metals that crystallize in this type of structure are gamma (I?) iron, aluminum, nickel, copper, gold, silver, etc. If a plane cuts any axis on the negative side of the origin, the index will be negative and is indicated by placing a bar (minus) sign above the index. Also, we are flexible in processing designs and logos brought in by you but most importantly we can adjust the designs to any glass size. Using a ×20 objective indicated by the dashed red circle in the schematic, we examined the area highlighted in images. Since the electron and proton have equal but opposite electrical charge, the neutral atom must contain an equal number of electrons and protons. To attain a stable structure, a nitrogen atom shares the electrons of three hydrogen atoms and in turn shares three of its electrons with the three hydrogen atoms to form ammonia (NH3).
The three dimensional network of imaginary lines connecting the atoms of a crystal is called the space lattice.
The first layer of marbles can be designated as A and the second layer as B giving the two layers a designation of AB as shown in the figure given below. Examples of metals that crystallize in this type of structure are magnesium, zinc, cadmium, etc. It may be noted that value of w is taken as zero since it is not required to move any distance on Z axis to reach point C. Our sandblasted glasses can be found on both interior and exterior applications such as glass balconies, doors, windows, shower screens, glass partitions, furniture etc. The organic solvent was seen to swell and significantly deform the channel segments constructed from PDMS after only 1 min of exposure in the hybrid device, while the homogeneous NOA device maintained its integrity even after 5 h of exposure. As shown above, when sodium and chlorine atoms are placed together, there is a transfer of electrons from the sodium to chlorine atoms, resulting in a strong electrostatic attraction between the positive sodium ions and negative chlorine ions. Miller indices of a plane passing through origin of space coordinates can not be determined without changing the location of the origin.
Atomic number of iron is 26 since there are 26 electrons balancing 26 protons in iron atom. PDMS channels allow for oxygen permeation, which terminates polymerization at the top and bottom faces of the device and thereby enables the creation of microparticles that can be removed via flow. The weight of an atom is approximately equal to the total weight of protons and neutrons and is called atomic weight of the element. Subshells are determined by the other three quantum numbers l, ml and ms which are measure of the angular momentum, the component of angular momentum in a specified direction and the spin of the electron on its own axis respectively. In contrast, gas-impermeable NOA channels do not produce such a lubricating layer, thus creating structures fixed to the surfaces of the channel. Monomer solution consists of PEGDA 700, red acrylate 13, and PI whereas rinse solution is pure PEG 200.
