Prevention of Oil Weepage in Silicone Automotive Gaskets 950196

This paper describes the development of elastomeric barrier coatings which can be applied to the surface of molded silicone rubber gaskets to reduce oil permeation and weepage while retaining the advantages of silicone rubber in automotive sealing applications. The paper will also include discussion of test methodology for measuring weepage as well as gasket design and compounding considerations to minimize oil permeability of silicone gaskets.
