Formulated glass flake unsaturated

Formulated glass flake unsaturated polyesters and vinyl esters... 

Formulated glass flake unsaturated polyesters and vinyl esters are in general use as corrosion protection systems, with good chemical resistance, and immersion temperature resistance up to 100 °C. Some reinforced systems are claimed to perform up to 125 °C, although experience has shown severe permeation at elevated temperatures, leading to blistering and rapid failure.
