1. It is very stable in water, low in dosage and strong in effect.

2. Suitable for esterification and condensation reactions at temperatures from 210 to 240 ° C.

3. When the reaction temperature reaches 80 ° C, the product will dissolve in organic acids, but will not affect the quality of the product.

4. This product can withstand high temperature reaction at 250 °C.

5. This product is neutral and non-corrosive.


Monobutyltin oxide is a kind of esterification catalyst which is resistant to hydrolysis and has a small amount of addition and high catalytic activity. It is mainly used for esterification and polycondensation at a reaction temperature of 210-240 ° C. The maximum reaction temperature can reach 250 ° C. The catalyst is neutral and has no corrosive effect on the equipment. After the reaction is completed, it does not need to be separated and does not affect the quality of the final product.


Monobutyltin oxide is widely used in the synthesis of saturated resins for the production of powder coatings and coil coatings. Aromatic polyol products for the synthesis and production of PBT engineering resins for polyurethane soft foams and rigid foams.

Add amount:

For the total reactants of 0.05-0.25%, the customer determines the amount of catalyst added according to his own production.


In a cool and dry warehouse, the lid should be closed in time to reduce contact with air.

Avoid contact with skin and mucous membranes, and rinse with plenty of water immediately after contamination.
