english name: fascat4100, butyltin oxide, butylenestannonic acid; butyltinhydroxide-oxide; butyltin(iv) hydroxide oxide; butylstannoic acid; n-butylstannoic acid; n-butyltin hydroxide oxide; n-stann butyltin hydroxide oxide;
?

physical and chemical properties:
monobutyl tin oxide 4100
fascat 4100 series is a multi-purpose product of barreled white solid powder. as an esterification catalyst, it has thermal stability and hydrolysis resistance. the product is neutral and non-corrosive. after the reaction is completed, it does not need to be separated. it is used as a polyester the catalyst can form a stable decomposition system in the coating. at the same time, it is also an intermediate raw material for the synthesis of polyvinyl chloride stabilizers and organic silicon curing catalysts. fascat-4100-monobutyl tin oxide: sn% ≥ 56 chf-4101, dibutyl tin oxide: sn% ≥ 48.2.

melting point: decompose directly at high temperature without dissolving.
?fascat4100 catalyst is a solid, hydrolytically stable catalyst.
?fascat 4100 catalyst mainly catalyzes esterification and polycondensation reactions at 210℃~240℃.
?during the reaction process, fascat4100 catalyst begins to dissolve in the carboxylic acid at 80°c and integrates with the final product without affecting the quality of the product.
?fascat4100 catalyst can be used at temperatures up to 250°c.
?fascat4100 catalyst is neutral and non-corrosive.
?
advantage:
? compared with the reaction system without catalyst, fascat 4100 catalyst can greatly shorten the reaction period of esterification.
? as only a lower reaction temperature is required, fascat4100 catalyst can reduce energy consumption.
? fascat4100 catalyst can reduce side reactions to *, such as: dehydration and oxidative degradation of polyols (especially secondary alcohols)
? fascat4100 catalyst can be mixed with other reactants in advance, no other special treatment is required, except to avoid moisture.
? fascat4100 catalyst does not need to be neutralized or filtered at the end of the reaction.
?
use:
? fascat4100 catalyst can be used for the synthesis of saturated polyester in powder coatings and coil coatings.
? fascat 4100 catalyst can be used in the production of unsaturated polyester in gel coats, sheet molding compounds and casting applications.
? fascat4100 catalyst can be used in the production of polymeric plasticizers.
?
storage and transportation:
it should be sealed and stored in a dry, cool and ventilated warehouse.
?
package:
packing: 25kg cardboard drum.
