Title: Dual cure solventless coating process. Phase 1, Final report

Abstract

The objective is to determine the feasibility of using the Dual Cure Photocatalyst technology for reduction of gaseous waste emissions through the minimization of coating solvent use. This is to be accomplished by developing a photocuring technology that would allow the use of solvent free (100% solids) formulations while preserving or improving upon the performance of conventional solvent based materials. Four Dual Cure Photocatalyst systems and one conventional catalyst system were investigated for use in curing combinations of epoxies with acrylates and acrylates with polyurethane precursors (polyol/polyisocyanate mixtures). Photocatalyst screening results showed that Dual Cure Photocatalyst Systems based upon cationic organometallic compounds alone or in combination with free radical photoinitiators or oxidants provide significantly better processing performance than systems based upon conventional catalysts or neutral organometallic compounds in combination with oxidants. Mechanical testing of materials prepared with the five catalyst systems showed that: (1) Dual Cure compositions can produce materials with better properties than the component parts and (2) Compositions cured with Dual Cure Photocatalysts produce materials superior to those cured with conventional catalyst systems in a number of cases. Cost, economic and energy analyses are presented based upon laboratory scale coating and curing studies.
