Tetraethoxysilane (TEOS CAS 78-10-4) Usage
Theproduct is mainly used in the manufacture of chemical-resist and heat-resist coatings, organosilicon solvents and adhesives of precision casting.
When be completely hydrolyzed, it will generate tiny silicon oxide powder which can be used in making fluorescent powder.
Applied to natural stones or other construction materials, it forms a silica-gel like binder (SiO2) that increases the substrate strength.
Polymerization of silicone resins for use in paints and other surface modification applications. And it is the intermediate for sol-gel process.
Further more, it can improve the performance of other resins and also it is the material for making silicon macromolecular compounds.
