FASCAT 4101/Butyltin chloride


Chinese name: plasticizer, catalyst mono, butyltin oxide, FASCAT 4101

Alias: FASCAT 4101 catalyst, plasticizer drying agent, monobutyltin oxide, FASCAT 4101, CAS 13355-96-9, chlorinated monobutylstannic acid, monobutyltin oxide chloride, monobutyltin oxide chloride, chlorinated monobutylstannic acid

English name: FASCAT 4101, Butyltin chloride , Butyltin chloride dihydroxide

Physical and chemical properties:

FASCAT®4101 is an amorphous, hydrolytically stable butyltin chloride dihydroxide. It can be used in esterification, polycondensation and transesterification reactions. The catalyst is used in the synthesis of saturated polyester resins for powder coatings.

FASCAT® 4101 is used to produce unsaturated polyester resins for gel-coating, sheet molding and cast molding applications. The temperature range for the generation of esters and antioxidants in the transesterification reaction is 140-180°C. The temperature range for the generation of esters and antioxidants in the transesterification reaction is 140-180°C.

The same temperatures are required to produce PBT engineering resins for the automotive and construction markets. It offers shorter esterification times, transesterification cycle times, lower reaction temperatures and efficient use of equipment.
