Product Description

Product Name:tin monobutyl triisooctanoate三丁基氧化锡
CAS No:23850-94-4
Molecular formula:BuSn(OOC8H15)3
Molecular weight:605.0
Physical Properties 
Density:1.13 g/cm3(@25℃)
Solubility:Soluble in most organic solvents, insoluble in water
Appearance:Light yellow liquid
Tin content:19%-20%
Features:It is a kind of esterification catalyst that is resistant to hydrolysis and has high catalytic activity, which is mainly used for reaction temperature.210-240 ℃ esterification and polycondensation reaction, the highest reaction temperature can reach 250 ℃. 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.



Monobutyl tin triisooctanoate is widely used in the synthesis of saturated resins for the production of powder coatings and coil coatings. ForPBT engineering resin synthesis and production of flexible polyurethane foam and rigid foam of aromatic polyol products.
Addition:For the total reactant 0.05-0.25%, the customer according to their own production situation, determine the amount of catalyst added.

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

Contact with skin and mucous membrane should be avoided. Rinse with plenty of water immediately after contamination.
