摘要:
A two part adhesive system is provided with the first part being a substrate-adhesive containing at least one of a urethane, an acrylic, or an epoxy based adhesive and the second part being an elastomer-primer comprising a halogenated polyolefin and, optionally a nitroso compound. Further provided is a method of post-vulcanization bonding of an elastomer to a substrate employing the adhesive outlined above.
摘要:
An aqueous adhesive composition containing a chlorosulfonated polyethylene latex, a polymaleimide compound, a nitroso compound and a metal oxide. The adhesive composition can be effectively utilized without a primer component and exhibits an unusually high resistance to pre-bake conditions and adverse environments. The adhesive also possesses the ability to effectively bond a variety of substrates.
摘要:
Compositions comprising at least one halogen-containing polymer, at least one aromatic nitroso compound, at least one salt of certain inorganic and organic acids, and, optionally, at least one maleimide compound, have been found to be unexpectedly effective as storage-stable, single-package, one-coat adhesive systems for bonding a variety of elastomeric materials, including vulcanizable and vulcanized natural and synthetic elastomer compositions, to themselves and other structural substrates.
摘要:
Resin compositions of high adhesivity which comprise (A) ethylene-vinylacetate copolymer or mixture of said copolymer with polyethylene, (B) chlorinated or chlorosulfonated polyethylene, (C) unsaturated carboxylic acids maintaining solid at room temperature and (D) organic peroxides or these components blended with phenolic compounds and/or acid-acceptors.
摘要:
Solutions of chlorosulfonated polyethylene or mixtures of sulfonyl chlorides and chlorinated polymers in polymerizable vinyl monomers having a Brookfield viscosity of up to about 1 million form excellent adhesive compositions which cure to high bond strengths. Acrylic monomers are preferred.
摘要:
PROCESS FOR BONDING ELASTOMERIC SATURATED ETHYLENE/ ALPHA-OLEFIN COPOLYMER OR ETHYLENE/ALPHA-OLEFIN-POLYENE TERPOLYMER OF LOW DEGREE OF UNSATURATION TO NATURAL OR SYNTHETIC FIBERS OR FABRIC. INVOLVES TREATING THE FIBERS OR FABRIC WITH AQUEOUS DISPERSION CONTAINING HALOGENATED OR CHLOROSULFONATED ETHYLENE/PROPYLENE/POLYENE TERPOLYMER AND PHENOL-FORMALDEHYDE RESIN; DRYING THE TREATED FABRIC; PLACING THE FABRIC IN CONTACT WITH A COMPOSITION OF THE ELASTOMER CONTAINING A VULCANIZING AGENT; AND HEATING THE ASSEMBLED PRODUCT TO VULCANIZE THE ELASTOMER.
摘要:
Disclosed is an aqueous adhesive composition which comprises an admixture of: (a) a first aqueous composition comprising, (i) one or more film forming polymers, (ii) one or more lower crystallinity polynitroso compounds, (iii) one or more higher crystallinity polynitroso compounds, and (iv) one or more bismaleimide-containing monomers; and (b) a second aqueous composition comprising (i) an aqueous dispersion of at least one phenolic resin which is a condensation product of a phenol and formaldehyde, wherein the aqueous dispersion is stabilized by at least one polyacrylate; (b) one or more latices formed from one or more halogenated polyolefins; and (c) one or more metal oxides.

摘要:
A chlorosulfonated polyethylene latex, which is safe for living bodies and the environment and can be used as a latex component in a resorcin-formalin-latex adhesive, contains an aqueous dispersion medium, chlorosulfonated polyethylene, and an emulsifying agent of a polyoxyalkylene alkyl ether sulfate of formula (I) below and a fatty acid salt. The latex is excellent in standing stability and mechanical stability. In formula (I), R1, R2, n, and M represent an alkyl group of 6 to 20 carbon atoms, hydrogen or a methyl group, an integer of 2 to 40, and an alkali metal, respectively. R1—O—(CH2CHR2—O)n—SO3M (I)
