Abstract:
Methods for bonding polymeric substrates to hydroxylated surfaces such as glass are disclosed. The polymeric substrates may be elastomeric substrates such as a natural or synthetic rubber. The method may comprise applying a compound comprising at least one alkoxy silane moiety and at least one moiety selected from a nitrosoaromatic or a nitrosoaromatic precursor to one of the substrates. The nitrosoaromatic moiety may be a nitrosobenzene. The nitrosoaromatic precursor may be a nitrosobenzene precursor, such as at least one of a quinone dioxime or a quinone oxime. Novel primers and compounds suitable for use in the bonding process are also disclosed.
Abstract:
The invention relates to a method for increasing the adhesion between the first surface of a first web-shaped material and a first surface of a second web-shaped material, the first web-shaped material and the second web-shaped material being fed continuously and with the same web direction to a laminating gap, in which the first web-shaped material and the second web-shaped material are laminated together by means of the first surfaces thereof, the two first surfaces of the first web-shaped material and of the second web-shaped material being treated with a single plasma simultaneously and preferably over the entire area, and namely preferably in such a way that the plasma is applied continuously to the two first surfaces, starting from before the laminating gap to the laminating gap, the laminating gap being formed by a pressing element and a counter-pressure device, which builds up a counter pressure, and preferably at least one of the lateral surfaces of the pressing element and of the counter-pressure device or both being equipped with a dielectric, characterized in that none of the two first surfaces/web-shaped materials are guided through the discharge zone of the plasma-generating device.

Abstract:
The invention relates to a method for increasing the adhesion between the self-adhesive surface of a web-shaped material and a surface of a substrate, to which substrate the web-shaped material having the self-adhesive surface should be applied, wherein the web-shaped material is continuously fed to a laminating gap, in which the web-shaped material having the self-adhesive surface is laminated onto the surface of the substrate, the self-adhesive surface of the web-shaped material and the surface of the substrate are treated with a plasma over the entire area, and namely in such a way that the plasma is applied continuously to the two surfaces, starting from before the laminating gap into the laminating gap, the laminating gap being formed by a pressing element and the substrate and the surface of the pressing element being equipped with a dielectric.
Abstract:
The invention relates to a method for treating substrates, comprising applying a composition, which comprises at least one latent alkyl borane and is substantially free of decomplexing agents for the latent alkyl borane, to a substrate (1) that has a material having unsaturated units, applying a radically curable substance to the substrate (1) pretreated with the latent alkyl borane, and allowing the radically curable substance to cure in order to form a composite structure. The method according to the invention is suitable in particular for applying paints, coatings, or sealing materials/filling materials to substrates, such as EPDM, NBR, and SBR, and for adhesively bonding such substrates. Composite materials adhesively bonded accordingly are distinguished by especially firm adhesion of the adhesive to the substrate, wherein conventional adhesives can be used, which have optimized properties with regard to the storage stability, open time, and cure time thereof.

Abstract:
The invention relates to a method for increasing the adhesion between the first surface of a first web-type material and a first surface of a second web-type material, the first web-type material and the second web-type material being supplied to a lamination nip continuously and with the same direction of the web. In said nip, the first surface of the first web-type material and of the second web-type material are laminated together and both first surfaces of the first web-type material and of the second web-type material are treated with a plasma over the whole surface, in particular such that the plasma acts continuously on the two first surfaces starting from a region in front of the lamination nip to right into the lamination nip. The lamination nip is formed by a pressure roller and a counter-pressure roller and at least one of the surfaces of the rollers or both are equipped with a dielectric. The plasma or the corona a produced by a nozzle. The first web-type material comprises an adhesive compound layer which is arranged in the first web-type material such as to form the first surface of the first web-type material.
