WHAT IS SILANE?
Silane is an inorganic compound with the chemical formula, SiH4. It is a colourless, pyrophoric, toxic gas with a sharp, repulsive smell, similar to acetic acid. Silane with alkyl groups is an effective water repellent for mineral surfaces such as concrete and masonry. Silanes with both organic and inorganic attachments are used as coupling agents. Organofunctional silane products range includes amino silane, epoxy silane, sulfur silane, acyl silane, vinyl silane, alkyl silane and phenyl silane etc.
The unique ability of silane to form covalent bonds in inorganic and organic components and the inherent stability of siloxane adhesion make this technology a core component for high-performance paints and coatings. These properties of silane play an essential role in the materials resisting physical, chemical, environmental and thermal degradation.
SILANE APPLICATION AND ADVANTAGES
Silane monomers are widely used in coatings in the form of organofunctional alkoxysilanes, acting as adhesion promoters, pigment treatments and cross-linking agents. Inorganic alkyl functional groups combine with various organic functional groups to form covalent bonds between organic polymers and inorganic surfaces (such as dyes, fillers, glass and metal materials).
Through the same coupling agent mechanism as described above, the organic polymer is combined with the inorganic surface. The combination of all alkoxysilanes and the inorganic surface is essentially the same, but to obtain the most performance from the silane, the silane’s organic functional properties must match the chemical properties of organic polymers in paints, inks, or coatings. The use of silane in coatings can improve adhesion, moisture resistance, chemical resistance, UV resistance, and corrosion resistance, and can improve the dispersion of fillers.
Silane gives coating many advantages:
Our Solutions
EVOSOL™ SILANE 661 is a bifunctional silane with active amino groups and hydrolyzable inorganic ethoxysilyl groups. With the dual nature of its reaction, it can organically bond inorganic materials (such as glass, metals, and fillers) and organic polymers (such as thermoplastics, thermosetting plastics, or elastomers). It is used as a tackifier, organic/inorganic interface surface modifier (corrosion protection, primer) or silicone polymer or crosslinking agent (moisture crosslinking polymer). It is a colorless and transparent low-viscosity liquid with an obvious ammonia odor, soluble in alcohol, aliphatic or aromatic hydrocarbons. It can also be completely dissolved in water and immediately react with water.
