摘要:
An anti-stick, non-liquid absorbing laminated gasket and a process for its preparation are disclosed in which a metallic base sheet has a bonded fibrous layer adhered to at least one face of the sheet. The fibrous layer contains a liquid-impermeable resinous impregnant and an anti-stick coat disposed along an outer face of the fibrous layer. The resinous impregnant may extend to the outer face of the fibrous layer while leaving fibers thereof exposed to which the anti-stick coat adheres. Or the resinous impregnant may extend beyond the outer face of the fibrous layer to form a skin and the anti-stick coat adheres to the extension of the impregnant after it is tackified by an organic solvent.
