Characteristic

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.


Use

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.


Storage

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