Abstract:
A silicone rubber-fluororesin laminate comprising a substrate, and a vulcanized silicone rubber layer and a fluororesin layer that are sequentially formed on the substrate; wherein the fluororesin layer is formed after an epoxy resin-containing silane based primer layer and a fluororesin based primer layer are sequentially formed on the vulcanized silicone rubber layer, and the epoxy resin-containing silane based primer layer contains 30 to 80 wt % of an epoxy resin and 70 to 20 wt % of a silane coupling agent. The silicone rubber-fluororesin laminate does not cause a reduction not only in the initial adhesion, but also in the adhesion between the vulcanized silicone rubber and the fluororesin even in a heated environment, such as a hot state or long-term heating.
