Silica Sol
CAS 112926-00-8

Silica Sol,CAS NO.112926-00-8,is a kind of colloid which is formed by nm-grade particles SiO2,dispersed in water. It has high bonding strength and high heat-resisting performance (1500-1600℃), used as the adhesive agent for various fireproof materials....

Product Details

Silica Sol

CAS NO:112926-00-8

Molecular formula:SiO2·nH2O

Properties:Silica Sol is a kind of colloid which is formed by nm-grade particles SiO2,dispersed in water.

Application:

1.JX IS a kind of Silica Sol of small sized particle diameter.Apart from characteristics of ordinary alkali silica sol,JX has small sized particle diameter,big specific surface,So it has the advantages of good smooth finish and high precision in size,compared with ordinary alkali Silica Sol.It also has the special usage in storage battery industry.

2.JA is a kind of silica sol with ammonium as its stable agent.For ordinary silica sol,the exist of Na+is a disadvantage when at high temperature or with the exist of catalyst or when is used directly as catalyst.Thus JX has its advantage without Na+,compared with ordinary Silica Sol.

3.ZA is a kind of neutral Silica Sol.Compared with ordinary alkali silica sol,ZA has no need to adjust PH value to maintain its stability.So ZA is practical in coating,especially under high temperature in ceramics and catalyst.

4.JK is a kind of silica sol of high drying speed.Compared with ordinary silica sol when used in precision casting,JK has the advantage of shorter dry time,1/2-1/3 of the ordinary time.Furthermore,it has improved its high temperature—resistant performance.
