Introduction of Amine Catalyst A33

Amine Catalyst A33 is a liquid catalyst containing 33% triethylenediamine (TEDA). This highly active tertiary amine catalyst promotes the reaction of isocyanates with polyols to crosslink the foam. And give flexible polyurethane foam good mechanical properties. If the amine catalyst A1 is used in combination, the best performance of the amine catalyst A33 can be obtained. Physical Properties: Shape: Colorless or light yellow liquid; Purity≥99%; Moisture≤0.5%; Viscosity (25℃): 100mPa.s; Density (20℃): 1.033g/cm3; Flash Point (PMCC): 79 ℃; Vapor pressure (38℃): 266Pa

Amine catalyst A33 product application: The active ingredient of A33 is triethylene diamine, a solution prepared from 33% triethylene diamine and 67% dipropylene glycol. A33 is mainly used as a gel catalyst for polyurethane foam, widely used in soft, semi-rigid, rigid polyurethane foam, coatings, elastomers. In the polyurethane foam system, isocyanate first reacts with triethylene diamine to form active Complex, the nature of the complex is very unstable. Once the urethane bond is formed, it will be freed, which is conducive to further catalysis. Triethylenediamine has strong gelation reaction and foaming reaction. The catalysis of polyurethane and hydroxyl is more selective. Amine catalyst A33 is suitable for all kinds of polyurethane foam manufacturing. It is completely soluble in water and fully mixed with polyols, fluorocarbons and stannous catalysts. In all foam formulations, triple amine catalyst A33 can replace double solid triethylene diamine, for example, 0.3php amine catalyst A33 can replace 0.1 php solid triethylene diamine. Amine catalyst A33 is widely used in flexible polyurethane foam, rigid polyurethane foam, large sponge, high-resilience sponge, high-resilience car seat, spraying rigid foam, imitation wood rigid foam, polyurethane composite material, waterproof coating, and polyurethane adhesive. There are a wide range of applications.
