The potential of UV-LED as UV source for wood coating curing will be discussed at the European Coatings Conference "Parquet and furniture coatings” in Berlin. In the field of UV?curable coatings, the replacement of mercury lamps with UV?LED lamps is of high interest nowadays.
Pro Guard Coatings is proud to offer UV Cured & Hybrid Coatings, a product line far superior to what is currently available on the market. Recent advances regarding photolatent additives for UV curing help to overcome the shortcomings of conventional UV curable systems. Parts of commercial vehicles, construction machines and agricultural machines, such as, for example, commercial vehicle axles, are frequently subjected to very severe stress by stonechips and corrosion during operation. Indeed, UV?LED devices show significant advantages compared to mercury lamps, including zero IR emission, lower energy consumption, shorter starting time, smaller sizes and no need of harmful compound elimination. Smart Finish has a longer pot life that extends the ability to use the material and minimizes unwanted waste. By suitable coating of these parts, an attempt is made to provide simple and efficient protection from such chemical and mechanical stresses. However, UV?LEDs also have challenging characteristics like monochromatic emission and lower power.
Pro Guard Coatings Smart Finish is east to apply, lasts longer and recoats WITHOUT stripping. This eliminate many potential health and environmental hazards including odor and additional waste. Our initial emphasis was on the production of house paints and later into specialty coatings. The Asia-Pacific is the largest UV coatings market, which consumed almost half of the total demand in 2013.


Recent advances in view of photolatent additives for UV curing help in doing away with the shortcomings of conventional UV curable systems. During coating, the composition should have good hiding power in combination with good curing and adhesive properties on a very wide range of substrates.
Smart Finish is changing the way facility maintenance personnel and contractors see VCT and wood coatings by eliminating additional crosslinks. The demand for UV coatings in the region is estimated to grow at a CAGR of about 9.9% from 2014 to 2019. There are intrinsic limitations associated with radical photo polymerization such as oxygen inhibition, insufficient curing of shadow areas, poor coating of thick and highly pigmented coatings, lack of adhesion on certain substrates. Furthermore, the composition should be capable of being applied by simple, conventional application methods. A laboratory curing device was developed, consisted in specially designed mirror equipment on which a UV?LED lamp of 390 nm radiation and 15.4 W power was fixed. It is projected that China and Japan were the biggest consumers of UV coatings in the region, followed by South Korea in 2013.
According to the author, all these limitations can be overcome by a recent development using photolatent additives and thus support the expansion of the scope of UV curing technology in industrial and automotive applications.
This patent application from Karl Worwag AG decribes a UV-curable composition for coating vehicle axles. The Chinese market for UV coatings is also the fastest growing market, which is primarily due to the growing manufacturing industry that is further pushing the demand for coatings, domestically. Photolatent bases are stable and inactive in the dark when incorporated in coating systems, but efficiently release tertiary amines or amidines on irradiations with UV or daylight. Also, the electronics and industrial coating end-use segments are driving the demand for high-performance coatings, which in turn is pushing the demand for UV coatings within the region.


Spruce veneer samples were coated according to the following system: wood sanding + 40 µm layer completely cured + fine sanding + 40 µm layer cured with varying speeds.
The new technology allows adjustable speed UV and daylight curing as well as post cure of poorly exposed and shadow areas on three dimensional objects. Among the UV?curable formulations designed, 2 radical and 1 cationic coating systems were proved to be completely curable under UV?LED radiation with speed up to 25 m.mn?1 and very good surface quality and transparency. It also extends the pot life of 2K systems which have to be mixed prior to the application. Due to the green nature of UV coatings and an extremely less curing time, it is seen as an incredibly attractive alternative by various end-user industries. Industrial coating is the biggest and the fastest growing end-user industry (being closely followed by electronics industry) of UV coatings, which is projected to grow at a CAGR of about 9.3% between 2014and 2019. In 2019, almost three-fourth of the demand addition in industrial coatings is projected to be by wood coatings segment.
China is the biggest market for industrial coatings as an end user in the UV coatings market. Also the demand of plastic coatings for electronic parts & flooring is accelerating at a significant pace which is in turn pushing the demand for UV coatings by this end-user segment. The industrial coatings segment is dominant across the globe unlike electronics segment which is majorly in Asia-Pacific.
