What are the commonly used polyurethane amine catalysts?

Commonly used polyurethane amine catalysts mainly include the following:

Organotin catalyst: Organotin compound is a commonly used polyurethane amine catalyst, such as dimethylstannite (Dibutyltin Dilaurate), diethylstannite (Dibutyltin Diacetate), etc. These organotin catalysts have good catalytic effects in polyurethane reactions, can promote the reaction between isocyanates and polyols, and accelerate the formation of amines.

Acidic catalyst: Some acidic substances can also be used as catalysts for polyurethane amines, such as phosphoric acid, zinc chloride, etc. They can play a catalytic role in the polyurethane synthesis process and speed up the reaction.

Metal salt catalysts: Some metal salt compounds are also used as catalysts for polyurethane amines, such as zinc salts, manganese salts, etc. These metal salt catalysts can effectively promote the polyurethane reaction.

Organic acid catalyst: Organic acid compounds are also commonly used as catalysts for polyurethane amines, such as benzoic acid, phthalic acid, etc. They play a catalytic role in polyurethane synthesis, helping to control reaction rates and product properties.

The above are some commonly used polyurethane amine catalysts. Different types of catalysts may show different effects under different conditions. It is very important to choose the catalyst that suits your production needs. When using catalysts, they need to be selected and controlled based on specific conditions and reaction requirements.
