摘要:
A nitrile rubber-metal laminated gasket material comprising a surface-treating agent layer containing a zirconium-containing compound, a phosphorus-containing compound, and silica; a vulcanizing adhesive layer; and a nitrile rubber layer, which are sequentially laminated on a metal plate. The nitrile rubber-metal laminated gasket material that has excellent heat resistance and exhibits sufficient adhesion even after being dipped in or exposed to long life coolant (LLC) in an actual use environment as a gasket, even when it is a laminate of a metal plate, such as SPCC or SPFC, and nitrile rubber.

Disclosed is a rubber-metal adhesive in the form of dispersed solids in a volatile liquid carrier, with a specified pigment grind and is sprayable at uniform film coatings on metal surfaces at 25 ± 2 solids content wt.% and a viscosity of from 50 to about 500 cps (Brookfield LVT 2 @ 30 rpm). The adhesive comprises a dispersion of solid particles comprising nitroso compound, halogenated polyolefin, acid acceptor and from 5% to 35 wt.% of inert, incompressible, spheroidal particles having a BET surface area of from 0.1 to 10 m2/g and a 50th percentile particle diameter (D50) of 5 to 25 µm.
摘要:
A method for bonding a material to a first substrate surface that includes providing a catalyst at the first substrate surface and then contacting that surface with a material that undergoes a metathesis reaction to bond the material to the first substrate surface. There are two embodiments of this method - a coating process and an adhesive process. ln the coating embodiment, the metathesizable material is contacted with the catalyst on the substrate surface so that it undergoes metathesis polymerization to form the coating. The adhesive process includes (a) providing a catalyst at the first substrate surface, (b) providing a metathesizable material between the first substrate surface and the second substrate surface, and (c) contacting the catalyst on the first substrate surface with the metathesizable material so that the metathesizable material undergoes a metathesis reaction and bonds the first substrate surface to the second substrate surface.
摘要:
To reduce the quantity of p-dinotroso benzole (DNB) needed by a third to a half without substantially adversely affecting the mechanical properties of metal/rubber bonds, it is proposed that DNB be deposited on a substrate and used in this form as a cross-linking auxiliary for the polymerisation or cross-linking of elastomers, especially in adhesively securing rubber to metal in the usual manner.
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.
摘要:
Compositions having a compound comprising at least one alkoxy silane moiety, and at least one moiety selected from a nitrosoaromatic or a nitrosoaromatic precursor and combinations thereof; and an aqueous or water containing carrier medium are provided for use in polymer bonding. The water may allow for substantial hydrolysis of the compound. Suitable polymers may have diene or allylic functionality within the polymer chain, for example an elastomer such as a natural or synthetic rubber. The polymers may be bonded to metals or substrates with hydroxylated surfaces such as glass. The nitrosobenzene precursor may be at least one of a quinone dioxime or a quinone oxime.
