Product Description

                                                                                Siwin-931  Methyltrimethoxysilane

 

 

 

 

Application

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 the hydrolysis of Siwin-931 substantially.
(Filler Modifier) Siwin-931 is used mainly to render a wide range of surfaces and materials water repellent (e.g.mineral fillers, pigment, glass cardboard). Siwin-931 may be 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.
Siwin-931 is also used in the production of silicone resins and condensation-curing silicone rubber.
