GENIOSIL® TM
GENIOSIL® TM is monomeric methyl silicate, also known as tetramethoxysilane, tetramethyl orthosilicate or orthosilicic acid tetramethyl ester. It is a colorless, low-viscosity liquid with an SiO2 content of approx. 40% by weight.
- CAS No. 681-84-5
- Empirical formula C4H12O4Si
- Molecular weight 152,22 g/mol
Properties
GENIOSIL® TM offers:
• storage-stable, low viscous liquid
• reactive and volatile silane (boiling point app. 121°C)
• tetrafunctional monomer
• liquid source of silica / silicone dioxide, either by hydrolysis or thermal deposition
GENIOSIL® TM is being used for the precipitation of silica (polymeric SiO2 structures) by complete hydrolysis or thermal decomposition. Methanol is generated as by-product.
The polymeric SiO2 structures firmly bind inorganic fillers and pigments and adhere well to different inorganic substrates like glass, ceramics or metall. Chemical and mechanical properties of the substrates can be improved by the thin SiO2 film, which is also highly heat-resistant.
Typical applications for GENIOSIL® TM are
• source of finely divided silica
• crosslinking agent, e. g. for silicone elastomers
• sol-gel processes
• silica coating on pigments, fibers and other surfaces
Packaging
GENIOSIL® TM is available in the following packaging units:
- 25 kg steel can
- 200 kg steel drum
Storage
GENIOSIL® TM must be stored in the tightly closed original container under exclusion of moisture. The "Best use before end" date of each batch is shown on the product label. Storage beyond the date specified on the label does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
