UV curing systems for automotive refinish applications

The combination of the UV flash equipment, which generates UV flashes in short intervals with a high and homogenous energy density, with UV curing systems for automotive refinish leads to a perfectly suitable procedure especially for spot- and micro-repair applications. The UV curing refinish primer technology is well introduced in the market and the repair process time can be reduced by up to 50% compared to conventional systems. The visualization of the reaction grade and speed of the UV-induced radical polymerization is important for development. The skillful combination of the UV flash equipment with a FTIR instrument enables real-time measurements under application oriented UV curing conditions. The influence of applied UV intensity, oxygen inhibition and effectiveness of the polymerization reaction is investigated.
