Abstract

Proprietary polyurea-based thermosets were produced from polyisocyanate and water glass (WG) using a phosphate-type phase transfer catalyst. WG was dispersed in the polyisocyanate resulting in water-in-oil (W/O) type emulsion. The polyurea matrix, formed after crosslinking, contained the WG derived silicate in coarse particles showing a broad particle size distribution. The mean particle size of the silicate was markedly reduced and its distribution narrowed when the polyisocyanate was hybridized with a peroxide crosslinkable vinylester resin (VE) when the amount of the latter was
