An aqueous adhesive composition, as for bonding nitrile rubbers to a metal substrate, has very good pre-bake resistance. The adhesive composition comprises a phenolic novolac or resole resin, chlorinated natural rubber, a reactive fillers, and precipitated silica. Utilization of the adhesive composition results in essentially failure of the nitrile rubber.
La présente invention concerne une composition adhésive aqueuse telle que pour fixer des gommes nitriliques sur un substrat de métal et présentant une très bonne résistance à la précuisson. Cette composition adhésive comprend une novolaque phénolique ou une résine résolique, une gomme naturelle chlorée, une garniture réactive, et un précipitat silicique. L'utilisation de la composition adhésive provoque essentiellement la défaillance de la gomme nitrilique.
