Product Details
Catalyst DPA Product Data Sheet
1. Description
Catalyst DPA (N-(3-dimethylaminopropyl)-N,N’-diisopropanolamine) is a reactive tertiary amine gelling catalyst designed for polyurethane systems. It covalently bonds into the polymer matrix, delivering balanced gel/blow control, low volatility, low odor, and reduced VOC/fogging. It is widely used in high-performance, low-emission PU foam and elastomer applications.
