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.

Composition ou coussin adhésif sans solvant renforcé à la silice comportant un mélange de caoutchouc, de la silice, un agent de couplage de la silice, un agent donnant du collant facultatif et peu ou pas de noir de carbone. La composition adhésive élastomérique peut être utilisée avec plusieurs autres couches de caoutchouc pour faire adhérer une bande de roulement vulcanisée ou non à une enveloppe de pneu vulcanisé. La composition adhésive élastomérique possède une bonne résistance à l'éclatement et une température finale très basse à l'essai d'éclatement.
