Introduction of Amine Catalyst A33-TMPDA-Tetramethylpropylenediamine

Amine catalyst A33 is a liquid catalyst containing 33% triethylenediamine (TEDA). This highly active tertiary amine catalyst promotes the reaction between isocyanate and polyol to cross-link the foam. And gives the soft polyurethane foam good mechanical properties. If used together with amine catalyst A1, the best performance of 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°C): 266Pa Amine catalyst A33 product application: The active ingredient of A33 is triethylenediamine, a solution prepared from 33% triethylenediamine and 67% dipropylene glycol. A33 is mainly used as a gel catalyst for polyurethane foam, and is widely used in soft, semi-rigid, and rigid polyurethane foams, coatings, and elastomers. In the polyurethane foaming system, isocyanate first reacts with triethylenediamine to generate 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 effects on gel reactions and foaming reactions. The catalytic effect is more selective, especially for polyurethane and hydroxyl groups. Amine catalyst A33 is suitable for all types of polyurethane foam manufacturing. It is completely soluble in water and completely miscible with polyols, fluorocarbons and stannous catalysts. In all foam formulations, triple amine catalyst A33 can replace one time of solid triethylenediamine, for example, 0.3php amine catalyst A33 can replace 0.1php solid triethylenediamine. Amine catalyst A33 is used in polyurethane soft foam, polyurethane hard foam, large sponge foam, high rebound sponge, high rebound car seat, spray hard foam, imitation wood hard foam, polyurethane composite materials, waterproof coatings, and polyurethane adhesives. Has a wide range of applications. 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, resulting in foam cross-linking. The flexible polyurethane foam has good mechanical properties. The optimum performance of the amine catalyst A33 can be obtained if the amine catalyst A1 is used in conjunction with the amine catalyst A1.
