Anti-Hydrolysis Agent for PU Sealant

This Anti-Hydrolysis Agent for PU Sealant chemically stabilizes polyurethane polymers by neutralizing moisture-sensitive sites, reducing ester bond hydrolysis. It improves long-term flexibility, adhesion, and resistance to water and chemicals. Suitable for moisture-curing and two-component PU sealants, it provides outstanding stability under temperature cycling and UV exposure. The additive ensures consistent viscosity and workability during application while preserving sealing strength and elasticity. Ideal for vertical joints, automotive seams, and structural applications.
