Novel chemistry for UV coatings: Photolatent base system optimises performance for refinish clearcoats

Radiation curing offers clear economic and environmental advantages. It combines low VOC formulations and low processing temperatures with fast cure speed. Nevertheless, current systems have some well-understood limitations. The development of a new pliotolatent base UV curing system is described, which is particularly well suited for use in the difficult application area of refinish clearcoats.
