Physicochemical properties:
Monobutyltin oxide 4100
FASCAT 4100 series is a barrel white solid powder multi-purpose products, as a catalyst for esterification, with thermal stability and resistance to hydrolysis, the product is neutral, non-corrosive, after the reaction is completed, do not need to be separated out, as a catalyst for polyester, can be formed in the coatings to stabilize the decomposition of the system, and at the same time is the synthesis of polychlorinated ethylene stabilizers, silicone curing catalysts, and other intermediate raw materials. 4100-Monobutyltin oxide: Sn%≥56 CHF-4101, Dibutyltin oxide: Sn%≥48.2.

?FASCAT 4100 catalyst is a solid, hydrolytically stable catalyst.
?FASCAT 4100 catalyst mainly catalyzes esterification and polycondensation reactions at 210℃~240℃.
?FASCAT 4100 catalyst starts to dissolve in the carboxylic acid at 80°C during the reaction and fuses with the final product without affecting the quality of the product.
?FASCAT4100 catalysts can be used at temperatures up to 250°C.
?FASCAT4100 catalyst is neutral and non-corrosive.
Advantages:
??FASCAT 4100 catalysts can significantly shorten the reaction cycle for esterification compared to catalyst-free systems.
??FASCAT 4100 catalyst reduces energy consumption as only lower reaction temperatures are required.
??FASCAT 4100 catalysts can minimize side reactions such as dehydration and oxidative degradation of polyols (especially secondary alcohols).
??FASCAT4100 catalyst can be pre-mixed with other reactants without any special handling, except for avoiding moisture.
??FASCAT4100 catalyst does not require neutralization or filtration at the end of the reaction.
Uses:
??FASCAT4100 Catalyst is used in the synthesis of saturated polyesters for powder coatings and coiled steel coatings.
??FASCAT4100 Catalyst is used for the production of unsaturated polyesters for gel coatings, sheet molding compounds and casting applications.
??FASCAT4100 catalyst is used in the production of polymeric plasticizers.
Storage and Transportation:
Should be kept sealed and stored in a dry, cool, ventilated warehouse.
Packaging:
Packing: 25Kg cardboard drums.
