Polyurethane Catalyst PC-77 for Balancing Tack-Free Time and Curing Efficiency in Coatings

Polyurethane Catalyst PC-77: Balancing Tack-Free Time and Curing Efficiency in Coatings Abstract: Polyurethane (PU) coatings are widely used due to their excellent mechanical properties, chemical resistance, and durability. The curing process, which dictates the final properties of the coating, is critically influenced by the catalyst used. PC-77, a tertiary amine catalyst specifically designed for PU coatings, offers a compelling balance between tack-free time and curing efficiency.…
