A sealant material that is relatively chemically inert toward plastics and adhesives is comprised of a homogeneous mixture of polymeric polyester, said polyester being derived from adipic acid, and silica, the polyester comprising more than about 50 percent by weight of the mixture and the fumed silica comprising less than about 20 percent by weight of the mixture. In a preferred embodiment, the sealant material further contains an organofunctional silane coupling agent, a polyfunctional bridging agent, a dispersing agent and a fluorosurfactant.
