Abstract
A rubber-metal laminated gasket material comprising a metal plate, a surface treating agent layer, an adhesive layer, and a rubber layer, the layers being sequentially laminated on the metal plate; wherein the surface treating agent layer is formed by applying a surface treating agent so that the coating amount on one surface is 30 to 1,000 mg/m, and the surface treating agent is free from chromium, has a mixing ratio of 20 to 90 wt. % of a fluorine-free titanium compound and 10 to 80 wt. % of alumina, and has a metal titanium content of 1 to 20 wt. %. The rubber-metal laminated gasket material has excellent LLC resistance under high temperature conditions.
