ABSTRACT:
A stable polyol-alkali metal silicate emulsion is produced by mixing and emulsifying an aqueous alkali metal solution, a polyol and an organic compound that will cause the aqueous alkali metal silicate solution to solidify. The polyol-alkali metal silicate emulsion may be used to react with compounds containing at least two isocyanate radicals to produce polyurethane silicate solid or foamed products which may be used for thermal and sound insulation, coating agents, adhesives, caulking agents and molded objects.
