Acure: new, ultra-fast drying, low VOC, isocyanate free technology for 2K coating applications

Two component urethane topcoats are well established in coatings applications. There is a need, however, for systems with increased productivity coupled with environmental and health and safety friendliness. This paper outlines the launch of a new, low VOC, isocyanate and organo-tin free, technology which meets these needs, which we have called 'Acure'. The system is built on a novel blocked catalyst (a base) and a kinetic control additive package used in conjunction with Michael Addition chemistry. Prototype paint formulae highlight the low VOC capability (<250 g/l) of this very fast drying 2K system (15 - 40 minutes, ambient) and the unique de-coupling of dry time and potlife (>5 hours), expected to trigger new paint and application process solutions. The chemistry of the system and comparative results versus other topcoats are presented. The results show that the system has significant potential to compete with existing two component topcoats in various market applications.
