auxiliaries for PU sealant

The auxiliaries for PU sealant include flow control agents, plasticizers, adhesion enhancers, and curing modifiers that ensure even film formation and mechanical integrity. They regulate curing speed, maintain elasticity, and prevent surface cracking. Chemically compatible with both polyether and polyester PU systems, they stabilize viscosity under storage and processing conditions. These auxiliaries improve long-term adhesion and moisture resistance, ensuring excellent performance under dynamic and environmental stress.
