Powder coating properties aredetermined to a great extend by the formulation and the cure conditions. This influence is even larger in the case of UV curable powder coatings, since the UV absorbance of additives and pigments directly affects the process of network formation. The effect of coating composition and layer thickness of the coating was s

Since many years, the goal of ink-makers is to improve the runnability and lithographic behaviour, dot gain, cure speed and odour for UV offset inks. But unfortunately, the formulation of UV curable printing inks depends on many variables both in ink making and in lithography process. One of the key properties of a good lithographic ink is its abil

During the last decade we observed an increasing scientific interest in fluid-dynamic effects caused by biological surfaces. It has been shown by Abramsom (1] and later by Barthlott and coworkers 2,3] that the well-known perfect cleaning of e.g. Lotus ( Nelumbo nucifera) leafs is caused by water droplets which are able to easily release impurity pa

A wide variety of radiometric instruments are now available for measuring the radiant characteristics of industrial and laboratory UV lamps. Relating these characteristics to the performance of a UV-cured product depends on how well the selected parameters match the critical factors of the cure process. Further, the distinction between process desi

     In recent years, cationic UV curing has become a well-established method in the coatings, inksand adhesives industries. Today, UV curing continues strong growth impelled by the generallyexcellent chemical resistance and mechanical properties of polymers produced by the UV cure ofsuch monomers as epoxides and vinyl ethe

Coatings on wooden substrates for furniture, flooring and interior are a main application for radiation curing lacquers. An important target for development of UV coatings on wood is to increase adhesion. Superior adhesion leads to better whitening behaviour (coin test) and abrasion resistance. Guidelines to improve adhesion on wood are:- Swelling

A new three-component photoinitiating system (based on isopropyithioxanthone ITX, amine AH and abifunctional benzophenone - ketosulfone BP-SK photoinitiator) for acrylate polymerizationreactions was investigated through time resolved laser spectroscopy. Addition of ITX to BP-SK I AH clearly enhances the efficiency of the photopolymerization of clea

Team UV began as one of those wild ideas;... Why not coat a racecar using the latest incoating technology? What better way to promote the advances in this leading edge paintfinishing than on a slick, head-turning, high-tech part?The project has gained momentum and promises to provide a platform for showing offthe industries capabilities for some ti
