摘要:
The present invention relates to a process for cold bonding elastomeric rubber substrates to non-elastomeric substrates of a different material, preferably metal, by use of a rubber treatment, preferably a primer composition and a 2k adhesive, preferably a 2k epoxy adhesive as well as the thus obtained bonded substrates.

This invention provides a product comprised of a substrate with a rubber composition attached to the substrate by at least one interlayer of a polysilsesquioxane composition having phosphate cross-linkages. The at least one polysilsesquioxane layer having phosphate cross-linkages is produced from a mixture of a silane coupling agent and a phosphatizing reagent.

A hose joint assembly includes a fitting, a hose receivable onto the fitting, and an adhesive for bonding the hose and the fitting together. For example, the adhesive is a microencapsulated two-part epoxy adhesive that functions as a lubricant when assembling the hose onto the fitting before curing.

A method of bonding an electrically conductive silicone gasket includes activating selected surfaces of the electrically conductive silicone gasket, applying a sealant having a corrosion inhibitor to at least a portion of the activated selected surfaces, and curing the sealant to thereby bond the electrically conductive silicone gasket with a substrate.
摘要:
This invention relates to a method for vulcanization-adhering a rubber composition to an adherent made from a brass or plated with a brass in the vulcanization adhesion between the rubber composition and the adherent made from the brass or plated with the brass by stably adhering a metal having a catalytic action to vulcanization adhesion reaction to the surface of the brass through a silane coupling agent as well as a reinforcing member for rubber article having an adhesion property to a coating rubber by subjecting a steel filament plated with a brass or a steel cord formed by twisting a plurality of such steel filaments to a surface treatment with a metal-containing silane coupling agent solution, and a rubber-reinforcing member composite and a pneumatic tire using such a reinforcing member for rubber article.
摘要:
A primer for vulcanization bonding, which comprises a copolymerization copolymer of amino group-containing alkoxysilane and vinyl group-containing alkoxysilane, and an organometallic compound, can give a metal-rubber composite having a water-resistant adhesiveness equivalent or superior to that of coating type chromate processing agent, without application of harmful coating type chromate processing to a metal, and thus can be effectively used in surface treatment of metals such as stainless steel, etc. for the production of seal products of rubber-bonded metal (e.g. oil seals, packings and gaskets), valves, vibration-controlled or vibration damped products (e.g. vibration-controlled steel sheets and vibration-damped rubber), industrial rubber products, etc.
摘要:
A process for preparing a composite structure of a metal bonded to a cured elastomeric hydrocarbon containing ethylene units and propylene units which consists essentially of coating the copolymer with a polyisocyanate having an -NCO functionality of at least three and wherein the -NCO groups are unhindered and on separate rings, applying an epoxy-based or chlorinated rubber/phenolic resin-based adhesive primer to the surface of the metal to be bonded and interposing between the surfaces an adhesive composition of a thermoplastic segmented copolyester (optionally, containing up to 60 weight percent of a thermoplastic resin which forms compatible mixtures with the segmented copolyester), applying heat and pressure to the metal and elastomer to bond the elements.
摘要:
A bonded composite structure of a cured elastomeric ethylene/propylene copolymer adhered to a metal substrate by a layer of segmented copolyester adhesive, said metal coated with chlorinated rubber/phenolic-based or an epoxy-based adhesive primer, said copolyester adhesive, optionally, containing up to about 60 weight percent of a low molecular weight thermoplastic resin which forms compatible mixtures with the segmented copolymer.
