Abstract
A glass coating composition for a fuel cell gasket is described. The coating comprises: a glass component effective to form an alkaline solution in the presence of an equivalent amount of water by weight, a binder component, a liquid carrier which is greater than 50% by volume: water, and a retarder effective to inhibit hardening of the composition. The glass coating composition is particularly useful in fuel cell gaskets and provides improved resistance to solidification in an aqueous dispersion.
