Applications

Silane OSi HIOSil 40 is used for the precipitation of silica (polymeric SiO2 structures) upon complete hydrolysis. The hydrolysis creates ethanol as a by-product. 

The polymeric SiO2 structures firmly bind inorganic fillers and pigments and adhere well to different inorganic substrates like glass, ceramics, or metal. The chemical and mechanical properties of the substrates can be improved by the thin SiO2 film, which is also highly heat-resistant.

• binder for zinc-rich anti-corrosive coatings, e.g. shop primers 

• binder for refractory fillers (production of ceramic shells and cores) 

• coating material for pigments and fibers

• liquid source of SiO2 as the binder 

• the crosslinking agent, e.g. for silicone elastomers 

• precision casting
