A water-based adhesive film-forming cover composition including: (i) at least one film forming polymer; (ii) at least one lower crystallinity first polynitroso compound; (iii) at least one higher crystallinity second polynitroso compound; (iv) at least one crosslinking agent; and (v) water as a carrier liquid; a bonding system including a combination of: (a) a water-based primer component; and (b) the above water-based cover component; a process for manufacturing the above bonding system; and a process of manufacturing a bonded article with the above bonding system. A bonded article, having a bonding line made from the above bonding system disposed between metal and rubber substrates, exhibits excellent stability against an aqueous urea-solution at temperatures of up to about 95° C.
摘要:
Use, as adhesion promoter intended for application to the surface of a substrate S1 made of thermoplastic elastomer polymer TPE which comprises a chain formed of an alteration of hard segments and of soft segments, for the purpose of the adhesive assembly of the said substrate S1 with another substrate S2, of at least one solvent of the hard segments and/or of the soft segments of the said thermoplastic elastomer polymer TPE.
摘要:
A bond between fluoroelastomer and polyamide resin is established by applying a silane-based primer composition to a surface of polyamide resin, heat treating at 100-200° C., applying a liquid fluoroelastomer composition to the primer coat at room temperature to 100° C., and heat curing at 100-200° C. for bonding the fluoroelastomer to the polyamide resin. The bond between fluoroelastomer and polyamide resin is maintained over a long period of time even in transmission oils.
摘要:
The present invention discloses a method of and composition for bonding a tubular first object to an inwardly located second object by using an adhesive coating. The coating includes water, a glue and a polymer. The coating is preferably applied to the inner surface of the first object and is dried so that the object may be stored for years prior to use. When ready for use, the coating is activated by wetting it with water so that the first tubular object can easily slide along the outer surface of the inwardly located second object to a desired position. The present invention further teaches a handgrip bonded to a golf club using the method described above.
摘要:
The bond strength between an elastomeric material and a secondary material is improved by applying a coating of isocyanate onto the surface of the elastomeric material prior to bonding the secondary material to the surface of the elastomeric material. The isocyanate is applied to the surface of the elastomeric material by exposing the elastomeric material to an atmosphere containing isocyanate vapor which is substantially uniformly distributed throughout the atmosphere and causing the isocyanate to deposit onto the surface of the elastomeric material. Then casting a second material onto the isocyanate coated surface.
摘要:
The present disclosure relates to self-sealing tires, a process for making said self-sealing tires and the use of a silicone composition cured via a condensation cure chemistry to form a self-sealing layer designed to function as both (i) a self-sealing tire puncture material, i.e., to seal puncture holes in the tread region of tires if/when punctured by a foreign body and (ii) as an adhesive for sound-absorbing foams adapted to reduce the noise generated by tires during travel.
摘要:
Provided is a vulcanized rubber surface treatment agent that enables firm adhesion between vulcanized rubbers without heating and has little effect on rubber deterioration. The vulcanized rubber surface treatment agent is used for adhering vulcanized rubbers to each other, which is an aqueous solution of hypochlorous acid having a pH value of 2 or more and 7 or less and an effective chlorine concentration of 100 ppm or more and 13000 ppm or less.
摘要:
Methods for forming a TPE-skinned composite include forming a skin layer having at least one surface and having a thermoplastic elastomer and an adhesive promoting agent; providing a foam layer; and forming the foam layer onto the said surface of the skin layer to form the TPE-skinned composite. Optional additives such as an organo-silane compound may be added to further improve the adhesion between the skin layer and the foam. The present disclosure also provides a TPE-skinned composite including a skin layer having a thermoplastic elastomer present in an amount of greater than 90 wt. %; and an adhesive promoting agent present in an amount of from 0.5 wt. % to 10 wt. % based upon the total weight of the skin layer.
