WACKER® Silane M1-Triethoxy

1 of 217 products in this brand
WACKER® Silane M1-Triethoxy is a clear, colorless liquid with an odor characteristic of alcohols. The use of WACKER® Silane M1-Triethoxy 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 higher.

Application Details

General processing information:

  • WACKER® SILANE M1-TRIETHOXY is highly miscible with standard organic solvents, such as alcohols, hydrocarbons and acetone.
  • WACKER® SILANE M1-TRIETHOXY 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 WACKER® SILANE M1-TRIETHOXY substantially. The relative and absolute rates of hydrolysis and condensation to form siloxanes will depend on various factors, such as pH (catalyst), concentration, temperature and solvent.

WACKER® SILANE M1-TRIETHOXY as a filler modifier:

WACKER® SILANE M1-TRIETHOXY 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.

WACKER® SILANE M1-TRIETHOXY as a constituent of sol-gel materials and silicones:

  • As a constituent of sol-gel materials, WACKER® SILANE M1-TRIETHOXY - on its own or together with other siliceous building blocks, such as silicates (SILICATE TES 28) or organofunctional silanes from the WACKER GENIOSIL ® range and perhaps stabilizing substances in aqueous or aqueous/organic solvent mixtures -undergoes a sol-gel process. Various properties (e.g. refractive index, flexibility, resistance to chemicals or scratches) of coatings produced in this way can be controlled by precisely adjusting parameters such as temperature, pH and concentration.
  • WACKER® SILANE M1-TRIETHOXY is used mainly to render a wide range of surfaces and materials water repellent (e.g. mineral fillers, pigments, glass, cardboard). WACKER® SILANE M1-TRIETHOXY 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.

Properties
  • The use of WACKER® SILANE M1-TRIETHOXY 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 M1-TRIETHOXY 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 WACKER® SILANE M1-TRIETHOXY used.
  • WACKER® SILANE M1-TRIETHOXY is an alkylalkoxysilane. The silane hydrolyzes slowly in the presence of moisture (ethanol is released) to form reactive silanols. These react further to produce oligosiloxanes and then polysiloxanes.
