A gasket and a process for preparing it are disclosed characterized in that the gasket is especially adapted for high temperature application, for example, in the range of about 1200 DEG F. to about 1600 DEG F. The gasket comprises a metallic base sheet having a sealant coating comprising a flexible, heat-cured, phenyl-substituted, hydrocarbyl-substituted polysiloxane resin containing metallic powder, such as aluminum powder, dispersed therein. Preferably, the polysiloxane resin contains at least 10 mole percent of the phenyl radical and may include in admixture an alkyd resin to assist in imparting flexibility.
