Boron trifluoride-diethanolamine complex is a stable Lewis acid complex formed by the coordination of BF₃ with diethanolamine (DEA). It exhibits excellent thermal and storage stability; while retaining Lewis acid catalytic activity, it significantly reduces the volatility and corrosivity associated with free BF₃.
This product serves as a high-performance bonding agent for HTPB-based solid propellant systems—particularly those based on ammonium perchlorate (AP)—enhancing interfacial adhesion between AP and HTPB, improving structural uniformity and mechanical properties, and boosting the overall stability and consistency of the propellant.
