Product Features:
FD4100 catalyst is a solid, hydrolytically stable catalyst that is active at low loadings.
It is used primarily to catalyze esterification and polycondensation reactions at temperature between 210 and 240°C.
FD4100 catalyst begins to solubilize in carboxylic acid at 80°C during the reaction and becomes incorporated into the final product without affectingthe quality of the product.
FD4100 catalyst can be used at temperatures up to 250°C. It is neutral and non-corrosive.
Benefits
FD4100 catalyst can significantly shorten esterification times when compared to uncatalyzed systems.
It offers energy savings due to lower reaction temperatures, as well as more efficient use of equipment.
FD4100 catalyst minimizes side reactions such as dehydration and oxidative degradation of polyhydric alcohols, especially secondary alcohols.
It can be charged up front with other reactants, and requires no special handling other than avoiding excessive exposure to moisture.
FD4100 catalyst does not require neutralization or filtration at the end of production.
Packaging & Delivery
Packaging Details:25kg/drum; as per customer's requirement
Delivery Time:Prompt shipemnt
Usage:
Monobutyltin Oxide is also known as butylhydroxostannane, butylstannonic acid and butylhydroxytin oxide.
It is mainly used as catalyst in the production of unsaturated polyester resins, saturated polyester resins and polyester polyols. It can also be a catalyst in the production of powder coating resins and polymeric plasticizers.
