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.

 

package:

Packing: 25Kg cardboard drum.
