UV curing systems for automotive refinish applications

摘要

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. (c) 2005 Elsevier B.V. All rights reserved.
