Abstract
Polyester silicate resinous products are produced by mixing an organic epoxide compound, hydrated silica, Lewis acid and a polycarboxylic acid and/or polycarboxylic acid anhydride, then heating the mixture to from 150.degree. C. to 250.degree. C. for 30 minutes to 4 hours. The polyester is silicate resinous products may be used as a coating agent, as a molding powder and as an adhesive.
Claims9
The process for the production of foamed polyester silicate resinous products containing an oxidated silicon compound by mixing and reacting the following components;
- (a) an oxidated silicon compound, 1 to 50 parts by weight;
- (b) an organic epoxide compound, 10 to 50 parts by weight;
- (c) an organic polycarboxyl compound selected from the groups consisting of polycarboxylic acid, polycarboxylic acid anhydride and mixtures thereof, 10 to 50 parts by weight;
- thereby producing polyester silicate resinous product then 1 to 100 parts by weight of the polyester silicate resinous product are mixed with 50 parts by weight of a polyisocyanate, up to 50% by weight of a chemically-inert blowing agent, up to 20% by weight of a foam stabilizer, up to 10% by weight of a polyisocyanate activator, up to 50% by weight of a curing agent and up to 5% by weight of an emulsifier, percentage based on the weight of the reactants, and allowed to react, thereby producing a foamed polyurethane silicate resinous product.
