CAS 13355-96-9 Plasticizer drier monobutyl tin oxide chloro monobutyl stannic acid monobutyl Butyltin chloride

Physical and chemical performance:

4101 is an amorphous, hydrolytically stable butyl tin chloride dihydroxide. It can be used for esterification, polycondensation and transesterification reactions. The catalyst is used to synthesize saturated polyester resin for powder coatings.

4101 is used to produce unsaturated polyester resins for gel coating, sheet forming and casting applications. The temperature range of ester and antioxidant formation in the transesterification reaction is 140-180°C.

The production of PBT engineering resins for the automotive and construction markets requires the same temperature. It provides shorter esterification time, transesterification cycle time, lower reaction temperature and effective use of equipment.
