Amine catalyst A33 introduction in Chinese and English
Amine Catalyst A33 is a liquid catalyst containing 33%Triethylenediamine (TEDA). This highly active tertiary catalyst Amine catalysts promote the reaction of isocyanates with polyols, cross-linking 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.

Amine catalyst A33 product application:
The active ingredient of Guangsiyuan A33 is triethylenediamine, a solution prepared from 33% triethylenediamine and 67% dipropylene glycol.
Guangsiyuan A33 is mainly used as a gel catalyst for polyurethane foams 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 form an active complex. The properties of the complex are very unstable. Once the urethane bond is formed, it will be freed, which is conducive to further catalysis. Triethylenediamine has a strong catalytic effect on gel reactions and foaming reactions, and is especially more selective 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, It is widely used in polyurethane composite materials, waterproof coatings, and polyurethane adhesives.
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.
Physical properties:
Shape: colorless or pale yellow liquid
A purity of 99% or more.
Moisture 0.5% or less;
Viscosity (25℃) : 100mPa. S;
Density (20℃) : 1.033g/cm3;
Flash point (PMCC) : 79℃;
Vapor pressure (38℃) : 266Pa
Application of amine catalyst A33:
Amine catalyst A33 is suitable for all types of polyurethane foams. It is completely soluble in water and can be thoroughly mixed with polyols, fluorocarbons and stannous catalysts. In all foam formulations, triethylamine catalyst A33 replaces one time solid triethylenediamine, for example, 0.3 php-amine Catalyst A33 replaces 0.1 PHP solid triethylenediamine.
Amine catalyst A33 is widely used in polyurethane soft foam, polyurethane hard foam, sponge foam, high rebound sponge, car seat high rebound foam, spraying hard foam, imitation wood hard foam, polyurethane composite material, waterproof coating and polyurethane adhesive.
