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.

?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.
