Applications
This product is mainly used in the manufacture of chemical-resist and heat-resist coatings, organosilicon solvents and adhesives of precision casting. When 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. It is the intermediate for the sol-gel process. Furthermore, it can improve the performance of other resins and also it is the material for making silicon macromolecular compounds.
Packaging and Storage
Be packed in 200L rums, 1000L IBC drum, ISO Tank
Be sealed and stored in a cool and well-ventilated place. Away from fire and water.
