WACKER SILANE M3-ETHOXY is used mainly to render a wide range of surfaces and materials water repellent (e.g. mineral fillers, pigments, glass, cardboard). WACKER SILANE M3-ETHOXY is also used in the production of silicone resins and condensation-curing silicone rubber. In a further application, aqueous sol-gel coating systems are used to produce organic-inorganic hybrids.
