1, used in precision casting industry: instead of silicate ethyl ester, non-toxic;Not only can reduce cost, used to make spare parts, high dimension accuracy, good casting finish, can make the shell mold strength is big, modelling is better than using sodium silicate quality;High temperature resistant coatings for mold, can make the coating has good heat resistance, reduce the heat loss of molten metal and mould and help release.
2, used in paint industry, can make the paint and firm, with a waterproof, fireproof, pollution resistance, high temperature resistant, coating strength, colour and lustre is gorgeous, do not fade, etc.Can also be applied to acid and alkali resistant, fireproof coating and coating of far infrared radiation.
3, binder applied to refractory: has the advantages of high bonding strength, high temperature resistant.
4, applied to textile industry: can be used for textile sizing agent, reducing end breakage rate;Used in textile dyeing, because has the caking property, fluid can form a good protection, increase the adhesion dyeing and so on.
5, application in paper industry: as sensitive paper treatment agent, cellophane anti-sticking agent, other office paper after processing, can improve the printing effect, make the color more bright.
6, the application in catalyst: in catalyst production, under certain conditions, as to accelerate the speed of catalytic carrier, in order to improve production efficiency.

7 and oil: in the aromatic hydrocarbon in the production of silicone monomer as catalyst, to improve the aromatics recovery has opened up a new way, in the oil industry, made from silica sol binder and catalyst.
8, the application of the battery: lead-acid battery electrolyte sulfuric acid, in turn easy to overflow, the motor vehicles to add a certain amount of sulfuric acid silica sol, gel, can prevent the sulfuric acid leaching splash and overflow, and can prolong the service life of the battery.
