Abstract
A stable polyol-alkali metal silicate emulsion is produced by mixing an aqueous solution of an alkali metal silicate or alkali metal metasilicate pentahydrate, a liquid polyol and a small amount of a salt of an alkali metal compound and a weak acid while heating the mixture to between 40.degree. C. and 100.degree. C. and agitating until the mixture emulsifies.
Claims17
The process for the production of a stable polyol-alkali metal silicate emulsion by mixing the following components:
- (a) aqueous alkali metal silicate solution, 1 to 50 parts by weight;
- (b) polyol, 25 parts by weight;
- (c) alkali metal salt of a weak acid, 1% to 20% by weight, percentage based on weight of alkali metal silicate solution.
