Abstract
A sealing material is presented which can be applied to surfaces and/or surfaces having seams, cracks, crevices and the like to hinder growth and colonization of bacteria while maintaining adhesion over a wide range of service, or use, conditions. The sealing material includes a fluoropolymer layer and a rubber based adhesive layer which is capable of adhering the sealing material to the surface or surfaces to be sealed. The invention combines the inherent anti-stick and hydrophobic properties of fluoropolymers with excellent adhesive characteristics of the rubber based adhesive.
