Development of isocyanate-free polyurethane technologies is continuing to gain considerable traction in the coating industry. Recent tightening of regulatory legislation has imposed strong incentives to develop alternative synthetic routes to more environmentally friendly polyurethane technologies. In this context, alkoxysilane cure chemistries provides coating scientists with a useful toolbox for designing new generations of compliant, high-performance PU coating systems. In the current paper, we will focus on new concepts utilizing an organosilicone approach towards NCO-free PU coating hybrids with improved physical and mechanical properties. Numerous formulation examples will demonstrate how such technologies can be beneficial for development of highly durable and scratch resistant clearcoat systems.
