Post Curing Catalyst

The Post Curing Catalyst promotes additional urethane or urea bond formation after the initial reaction, improving polymer network density. It enhances mechanical properties such as hardness, compression set, and thermal deformation resistance. This catalyst is suitable for both thermoset and cast polyurethane systems, functioning efficiently under moderate temperatures (80–120°C). It maintains low volatility, uniform dispersion, and compatibility with polyester and polyether polyols, ensuring smooth post-curing reactions.
