Encapsulated Polyurethane Heat-Sensitive Catalyst for Extended Adhesive Pot Life: A Comprehensive Review Abstract: This article presents a comprehensive review of encapsulated polyurethane (PU) heat-sensitive catalysts designed to extend the pot life of PU adhesives. Traditional PU adhesives suffer from limited pot life due to the inherent reactivity of isocyanates and polyols. Encapsulation of catalysts within...
