New applications in consumer electronics are driving the need for 3D packaging to produce smaller, higher performing, lower cost device configurations for use in applications such as memory and wireless devices.
While this application is complex, it demonstrates the potential of applications for bonding to glass or even plastics, using long-wavelength photoinitiators and UV lamps that provide substantial long-wavelength UV.

AboutWelcome to the offical ergonomics blog of The Human Solution and UPLIFT Desk, written by our ergonomic experts. The fundamental requirement is that the active UV wavelengths exceed the cut-off transmission wavelength of the glass or plastic. We are a new name with a proven UV cured CIPP lining system, with thousands of kilometres of UV cured CIPP liners installed around the world. We reline your sewer pipes and culverts on time, on budget and with the minimum environmental impact. Whether you need to rehabilitate a small section of narrow diameter pipe or you have large diameter culverts to refurbish, iLine can meet your exact needs. And with curing times of roughly half those of hot water cure systems, installations costs, time on site, pollution and localized disruption are minimised. Many conventional floor finishes take up to a week to cure, leaving some rooms out of commission for a while. You know you need to do it, but the thought of losing business while you wait for your floors to dry can cause many business owners to put off the project. A typical system contains hexavalent chromium, or chromate, to provide high, active corrosion protection, and is made up of three layers applied on a prepared surface.
In fact, if you compare us to the competition in quality, stability, price, lead time, customer service, and configuration options, you’ll see that no one comes close to UPLIFT.
As wafer thickness decreases to 100µm and below, manufacturing challenges arise because ultra-thin wafers are less stable and more vulnerable to stresses, and can be prone to breaking and warping—not only during grinding but also at subsequent processing steps. This technique has facilitated bonding of the face glass to all sizes of LCD displays, and DVD bonding, in which the adhesive is cured through a polycarbonate layer. We have a hugely experienced team of lining engineers and project managers, some of whom have worked with UV cured CIPP lining systems since their introduction to the UK in 2004.
What’s more, EnviroCIPP’s remarkable features, such as speed of curing, high flexural strength and elasticity, structural integrity and water tightness make it the most cost-effective, long life lining solution available in the UK, consistently outperforming traditional and inferior needle felt liner systems.
But, we’ve come a long way in the hardwood flooring industry, and new technology has increased the drying time of floor finishes making it much more convenient (and cost effective) for business owners to get their floors refinished.


UV lighting is used to instantly dry some floor finishes, making this the finish of choice for busy home and building owners. It has been developed for use as a coating and is ideal for coating and doming applications.
However, hexavalent chromium is an extremely toxic, carcinogenic, mutagenic and environmentally hazardous compound. It’s our mission to provide the best product at the best price, to keep as many people as possible healthy at work. Such processes eliminate the need for nitrogen inerting of adhesives, whose surface cure would otherwise be inhibited by oxygen. If you can’t walk on your floors, that pretty much leaves the rest of the house or business shut down as well. Beginning in 2017, the use of chromate will be subjected to authorization under the REACH directive.Hence, the replacement of chromate compounds is an urgent and major issue for the aeronautic industry. Webb, “The heart of the system is a family of 100% solids, liquid UV-curable acrylic adhesives.” The key to this process is the bonding of the wafer to a glass carrier using an adhesive that is UV-cured through the glass (Fig. The more quickly we can dry the finish, without compromising its integrity, the more quickly you can open the doors to customers and guests. Up to now, Airbus Group Businesses Units, including Airbus, have succeeded in replacing chromate in anodizing and etching (chemical acid treatment to deoxidize and prepare metallic surfaces) steps. In addition, different alternatives based on inorganic and organic inhibitors, low-temperature plasma deposition or sol-gel coatings1 have been investigated. The glass carrier provides the rigidity and strength to the wafer during subsequent processing.
Large amounts of resin in saltwater baitfish patterns can take longer to cure BUT not as long or as inconvenient as using a drying wheel if using two part resins. To date, none of these approaches are as efficient as chromate-based coatings.In the framework of the UV-Curable Hybrid Sol-Gel Coatings for Aeronautical Substrates (MHYRCEA) project belonging to The French National Research Agency (ANR) research program, we combined a UV-curing technology and hybrid sol-gel chemistry to develop a single-step route toward chromate-free coatings. The UV-driven procedure is compliant with novel environmental regulations and the reduction of manufacturing cycle time in the aeronautic industry. Webb, a specially formulated liquid UV-curable adhesive is spin-coated onto the wafer and the wafer is then vacuum-bonded to the glass carrier, which has been treated with a release layer of a light-to-heat conversion (LTHC) coating. The mounted wafer is processed using standard backgrinding equipment, requiring no significant backgrinding process changes.
The glass is separated from the adhesive using a laser debonding process that decomposes the LTHC layer.
Irgacure 250, denoted I250, ((4-methylphenyl)[4-(2-methylpropyl)phenyl]iodonium hexafluorophosphate at 75% in propylene carbonate), was used as a photoacid generator (PAG). Darocur 1173, denoted D1173, (2-hydro-2-methyl-1-phenyl-propan-1-one), was used as the radical source. The cationic resin used was an epoxy resin (denoted ER) and the radical resin was a dimethacrylate resin.Two UV-cured hybrid sol-gel coatings were compared to three DTM coatings cured at room temperature.

Coatings were applied on the substrates (AA2024-T3 or steel panels or BaF2 pellets) using an automatic film applicator equipped with a wire-wound bar.
Aluminum panels were specifically treated before application with an alkaline degreasing solution and acid etching. Use this material and you’ll wonder why you ever used epoxy or solvent based products.
This test was performed according to the ISO 9227 standard and compared different coatings on corrosion protection in an artificial atmosphere.The coated panels were placed into the cabinet at 35 °C ± 2 °C on racks with an angle of 20° ± 5° from vertical. The irradiation device was a Hamamastu L8252 He-Xe equipped with a reflector at 365 nm and coupled with a flexible light guide. During UV irradiation, the evolution of the band at 3050 cm-1 (epoxy C-H stretching) was selected to determine epoxy function consumption.


The disappearance of the vibration band at 2840 cm-1 (CH3-symmetric stretching) enables assessing hydrolysis kinetics of the methoxy functions.Nuclear Magnetic Resonance Spectroscopy (NMR) The 29Si cross polarization Magic Angle Spinning (CP MAS) solid state NMR experiments were performed on a Bruker Avance II 400 spectrometer with a Bruker double channel 7 mm probe.
Ten measurements were performed for each sample and averaged out.UV and Chemical ResistanceThe QUV accelerated weathering test simulated outdoor weathering and reproduced the damage caused by sunlight and rain. Coated panels were exposed to chemicals at room temperature by drop contact or by full immersion.Adhesion EvaluationTo assess the resistance of coatings to separation from substrates, cross-cut tests were performed according to the ISO 2409 standard. The combination of both organic and inorganic photopolymerization through a one-step UV-curing process led to the formation of innovative coatings having interesting corrosion protection performance since only few corrosion pits were observed after 400 h exposure to SST (Figure 1). The simultaneous organic and inorganic polymerizations can contribute advantageously to the formation of homogeneous hybrid materials with minimal or no phase separation. The epoxy function consumption was only slightly influenced by the length of the alkyl chain, while hydrolysis was slower with longer alkyl chains. The silicon atom environment was determined for different alkyltrimethoxysilane precursors (Figure 3). The absence of resonances corresponding to T0 sites means that all of the Si atoms were involved in some degree of Si-O-Si crosslinking, proving the efficiency of sol-gel reactions.
The length of the alkyl chain affected the density of the inorganic network since the proportion of T1 species increased with alkyl chain length.Surface HydrophobicityWater contact angle measurements enabled the assessment of the hydrophobicity of the film surface. Moreover, the addition of only 5 wt % alkyltrimethoxysilane precursor increased the water contact angle from 76° to 101°. Thus, the hydrophobicity is thought to hinder water and corrosion initiator penetration, thereby retarding the hydrolysis of Si-O-Al bonds and the appearance of corrosion phenomenon. UV-Cured Hybrid Sol-Gels versus DTM Formulations Corrosion Protection Performance The main required property for coatings applied directly on metallic substrates is corrosion protection. Corrosion protection performance was evaluated on the AA2024T3 (reference aluminum alloy substrate in the aeronautic industry) and on steel panels.Depending on the substrates, two UV-curable hybrid sol-gel formulations could be chosen. In fact, the composition was adapted to the substrates to give the best corrosion protection performance.UV-cured hybrid sol-gel coating (UV HSG2) was the most efficient coating to achieve very high corrosion protection on AA2024-T3 (Figure 5). Table 2 presents chemical resistances of UV-cured hybrid sol-gel coating versus DTM coatings.
Figure 6 represents the gloss retention at 60° measured for the UV-cured hybrid sol-gel coating and the three DTM coatings. The DTM coating formulated with the acrylate dispersion was the best coating in regard to UV resistance. The developed UV-cured hybrid sol-gel coating met the requirements in terms of gloss retention.Adhesion on CompositesComposites are increasingly used in the aeronautical industry. In this case, corrosion protection performance is not useful, but very strong adhesion of the coating to the substrate is expected.
To examine this property, the UVcurable hybrid sol-gels were applied on CFRP (carbon fiber reinforced plastic – epoxy matrix) panels with the surface prepared by mechanical abrasion. Coating adhesion was evaluated after UV curing and after 14 days immersion in water by cross-cut test.
