Abstract
A high surface energy (HSE) rubber compound contains EPDM. The compound may include a hygroscopic inorganic filler and/or calcium oxide. An article contains an HSE rubber composition adhered to a substrate with an adhesive. The substrate may include metal or glass. The adhesive may be an epoxy adhesive or a polyurethane adhesive.
