Hydrolysis Stabilizers for PU Sealant

This Hydrolysis Stabilizer for PU Sealant chemically protects the polymer matrix from hydrolysis by neutralizing reactive sites. It improves resistance to moisture ingress and preserves elasticity under long-term stress. Suitable for one-component moisture-curing and two-component polyurethane sealants, it ensures consistent viscosity and performance. The stabilizer also enhances UV stability and mechanical durability, making it ideal for structural joints, curtain wall sealants, and automotive sealing systems.
