Product description: WACKER® SILANE M3-ETHOXY is a clear, colorless liquid with an odor characteristic of alcohols.

Properties: The use of WACKER® SILANE M3-ETHOXY to render fillers water repellent considerably improves their dispersibility and reduces their sedimentation tendency. Mineral-filled plastics can thus be processed more easily. Additionally, resistance to moisture and chemicals is much increased. WACKER® SILANE M3- ETHOXY can be used as a constituent of silica gels, silicone resins and silicone rubber. In such compounds, the degree of curing and hence mechanical properties, such as elongation at break, modulus of elasticity and a coating's flexibility, can be controlled precisely by varying the amount of SILANE WACKER® SILANE M3-ETHOXY used.

Special features: WACKER® SILANE M3-ETHOXY is an alkylalkoxysilane. In the presence of moisture hydrolysis commences, releasing ethanol followed by the formation of reactive trimethyl silanols. These, in turn, can react with hydroxyl groups present on inorganic surfaces and coupling with such substrates ensues. The monofunctional feature of WACKER® SILANE M3-ETHOXY enables the formation of a silane monolayer via a defined reaction with hydroxyl containing substrates.

Application: 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 andcondensation-curing silicone rubber. In a further application, aqueous sol-gel coating systems are used to produce organic-inorganic hybrids.
