Storage Information

Qiguang Group recommends that our catalysts be stored in a dry and cool area under appropriate ventilation conditions. Each container should be closed tightly to avoid contamination with moisture or other negative influences that could change the products’ performance in the end use. The optimum storage temperature is between 10 °C and 30° C. Lower and higher storage temperatures are not preferable and should be avoided.

Application scope:

Tris(dimethylaminopropyl)hexahydrotriazine has excellent foaming/gelling ability of polyurethane rigid foam highly active trimer catalyst, which can be used together with other catalysts.

Tris(dimethylaminopropyl) hexahydrotriazine is mainly applicable to the catalytic effect of polyurethane and polyisocyanate reactions, with slightly higher catalytic selective activity for polyurethane than polyisocyanate reactions in terms of performance, and is often used for pressboard polyurethane rigid foam, sprayed rigid foam and molded rigid foam;

Tris(dimethylaminopropyl)hexahydrotriazine is more suitable for polyisocyanate hard foam sheets, various foaming agent foaming (including full water foaming) and other processes, and has excellent performance in water foaming hard foam systems;

Tris(dimethylaminopropyl)hexahydrotriazine is widely used in microporous polyurethane elastomer and high resilience foam products.
