Tetraethyl orthosilicate (TEOS) is a volatile silicon alkoxide used primarily as a chemical precursor for producing silica via hydrolysis and condensation (sol-gel) and as a crosslinking/functional silane in coatings, adhesives and specialty materials. TEOS is supplied in industrial, technical and reagent grades with lot COA and standard commercial packaging.
Application
- Silica precursor for sol-gel and thin films
Used as the primary alkoxide precursor to synthesize colloidal silica, gels, aerogels, thin films and SiO₂ networks via controlled hydrolysis/condensation. - Coatings and surface treatments
Used as a crosslinking silane and reactive diluent to improve adhesion, scratch resistance and chemical stability in coatings and sealants. - Adhesives and composite binders
Employed to enhance inorganic–organic bonding, act as a coupling agent precursor and to tune cure/gel behavior in composites and adhesives. - Ceramic and zeolite synthesis
Serves as a silica source in specialty ceramic and zeolite syntheses where controlled SiO₂ release is required. - Electronics and optics processing
Used in sol-gel derived dielectric films, spin-coating, surface passivation and thin-film deposition applications. - Analytical and laboratory reagent
Provided in small packs for R&D, method development and process optimization.
