Product Description

Description

Siwin-931 is highly miscible with standard organic solvents, such as alcohols, hydrocarbons and acetone. Siwin-931 is practically insoluble in neutral water and reacts only slowly to form silanols and higher condensation products.  Addition of a hydrolytic catalyst (inorganic/organic acids, ammonia or amines) accelerates thehydrolysis of Siwin-931 substantially.

 

Application

1. Used mainly to render a wide range of surfaces and materials water repellent (e.g.mineral fillers, pigment, glass cardboard).
2. Used pure or in solution to treat fillers, using suitable mixing equipment. It may be necessary to first pre-treat the substrate with water and/or a          catalyst.
3. Used in the production of silicone resins and condensation-curing silicone rubber.
