Silica reinforced solventless elastomeric adhesive compositions

摘要

A silica reinforced solventless adhesive composition or cushion comprises a blend of rubber, silica, a silica coupling agent, an optional tackifier, and low or nil amounts of carbon black. The elastomeric adhesive composition can be utilized with various other rubber layers to adhere a cured or uncured tire tread to a cured tire casing. The elastomeric adhesive composition has good blowout resistance and a very low, final blowout test temperature.
