Abstract

The present invention relates to an oil-bleed self-bonding liquid silicone rubber composition having both self-bonding and self-lubricating capabilities. The oil-bleed self-bonding liquid silicone rubber composition exhibits self-bonding capability in particular to substrates that contain residual hydroxyl groups or other residual hydrosilyl-reacting groups on their surface, including polycarbonate, polyester, polyamide, polysulfone, polyurethane, phenolic resin, epoxy resin, cellulose, glass and the mixture thereof.
