ABSTRACT:
Alkali metal unsaturated polyester silicate resinous products are produced by mixing a polyhydroxy organic compound, an alkali metal silicate and an unsaturated polycarboxylic acid, then heating the mixture to a temperature between the melting point of the polycarboxylic acid and the boiling temperature of the polyol while agitating until the reaction is complete. The products may be used in laminates and as coating agents.
