A composition for the promotion of adhesion between a rubber formulation and a textile substrate is provided. The inventive composition comprises either a mixture of specific amine functional silanes and organo-functional silanes having reactive groups or groups with an affinity for rubber. The inventive method entails the use of the inventive composition or a silane compound having both an amine moiety and a reactive group having an affinity for rubber formulations, particularly an unsaturated carbon-carbon bond. The composition may be utilized to adhere any standard reinforcement-type textile, such as polyester or polyamide, to a standard rubber composition, such as SBR, NBR, or EPDM. A method for adhering textiles to rubber formulations is also provided involving a pre-dip, -spray, -coat, and the like, of the inventive composition on a reinforcement-type textile surface followed by the contacting of the rubber formulation. Optionally, and preferably, the process involves the extra utilization of resorcinol-formaldehyde latex as an effective bonding agent to improve the adhesion between the two layers. The resulting textile-reinforced rubber product may be utilized as an automobile fan or timing belt, an automobile tire component, and any other rubber article which requires long-lasting, durable textile reinforcement.
An adhesive composition for the promotion of the adhesion of a rubber substrate to a textile substrate, said composition comprising at least two layers, wherein a first layer comprises at least one RFL and a second layer, bonded directly to said RFL layer, comprises at least one component selected from the group consisting of i) at least one functional silane containing both an amine-functional group and a moiety containing a radical selected from the group consisting of a mercapto moiety, a sulfide moiety, an isocyanate moiety, an epoxy moiety, a pyridine moiety, a hydrophobic saturated alkyl moiety, and a moiety having at least one unsaturated carbon-carbon, and ii) a combination of at least one aminosilane selected from the group consisting of
An adhesive composition for the promotion of the adhesion of a rubber to a textile substrate, said composition comprising at least one RFL and at least two different silane constituents;
