摘要： Polymer-base paints, such as acrylic or urethane paints, are used as coatings on substrates of elastomeric compositions which are heat cured compositions in which the elastomer has at least 0.5 mole percent unsaturation. These elastomeric substrates are formulated with a heat reactive phenol-formaldehyde type resin, a metal oxide or halide, the metals of which are selected from Groups IIB, IIIB, IVB or VIII of the Periodic Table and an additional halogen donor in the event that the other components bear no halogen groups. The elastomeric substrate may also contain fillers, such as carbon blacks, finely divided silica, talcs, or clays and plasticizers such as a naphthenic type oil. The halogen employed is chlorine or bromine. Optionally, the heat reactive resins are chlorine- or bromine-substituted alkylated phenolformaldehyde resins. These are preferably employed. The painted elastomeric compounds are used as sight shields, door gaskets, bumper guards, rub strips, grill housings, tire sidewalls and so forth, in the automotive manufacturing industry.

摘要： Rubber matls. contg. >=25 wt.% ethylene-propylene rubber and/or butyl rubber can be painted after first priming with an org. solvent soln. of a halogenated polyalkene with or without polychloroprene. Pref. primers contain chlorinated polyethylene or chlorinated polypropylene, polychloroprene and additives such as amines, amides, urea, dibutyltinidilaurate, etc., to improve the adhesion. The primer soln. is applied to the rubber, dried and pref. stoved e.g. for 5-40 mins. at 50-150 degrees C. Pref. coating for the primed rubber is a polyurethane paint giving a tough flexible wear resistant finish.

摘要： Rubber articles, such as surgeon's gloves, are provided with a synthetic resin slip coating by contacting the rubber surface with a synthetic resin latex composition. The slip coating is adherent to the rubber substrate and is very extensible without adverse effect. The synthetic resin slip coating includes from 5 to 90 percent by weight of a first resin copolymer component selected from the group consisting of vinyl chloride-alkyl acrylate copolymer, vinylidene chloride-alkyl acrylate copolymer, and vinyl acetate-alkyl acrylate copolymer, and correspondingly, from 95 to 10 percent by weight of a second resin copolymer component selected from the group consisting of vinyl chloride-vinyl ester copolymer, and vinylidene chloride-vinyl ester copolymer.

The elastomer may be a copolymer of vinyl acetate (45-95% by wt.) and ethylene, polybutadiene, a copolymer of butadiene with methyl methacrylate, styrene and/or acrylonitrile, polyisoprene and/or polychlorobutadiene. The hard polymer may be polyvinyl chloride, polymethyl methacrylate or polystyrene.

摘要： 1443774 Coated rubber surface EXXON RESEARCH & ENG CO 14 Jan 1974 [9 Feb 1973] 6445/73 Heading B2E [Also in Division C3] A polyurethane paint or an acrylic paint is applied to a rubber surface which is either (1) rubber derived from a composition comprising 30-100 parts by weight per hundred parts of rubber of halogenated butyl rubber which has been cured using a metal oxide or halide (especially an oxide, chloride or bromide of zinc or tin) in the presence of an alkyl phenol polysulphide and/or a non-reactive phenolaldehyde resin (a number of which are specified), or (2) a blend comprising an. ethylenepropylene-diene terpolymer (EPDM rubber) and a halogenated rubber cured with sulphur or a sulphur-containing vulcanising agent using a metal oxide or halide in the presence of a non-reactive phenol-aldehyde resin. Composition (1) may be of chlorinated or brominated butyl rubber (as defined below) or blends thereof with natural rubber, styrene-'butadiene rubber (SBR), EPDM rubber, polybutadiene, acrylonitrile-butadiene rubber, polychloroprene, polyisoprene or chlorosulphonated polyethylene and particular compositions comprise (by weight) 80 parts of chlorobutyl rubber and 20 parts of natural rubber; 35 parts of chlorobutyl rubber, 25 parts of natural rubber, 25 parts of SBR and 15 parts of EPDM; and 50 parts each of chlorobutyl rubber and EPDM. The diene monomer of the EPDM may be 1, 5- hexadiene, 1, 5-octadiene, or methylidine or ethylidene norbornene. Composition (2) may comprise 70% by weight EPDM and 30% chlorobutyl rubber or a blend of EPDM with polychloroprene or chlorosulphonated polyethylene. The rubber, which may be a radial tyre sidewall formulation, may be cleaned with a hexane solvent before painting. The "butyl rubber" to be halogenated for use in composition (1) comprises 85-99.9 wt. % of a C 4-8 iso-olefin such as isobutene and 0.1-15 wt. % of a C 4-14 multi-olefin such as butadine, dimethylbutadiene, piperylene or isoprene. The rubber compositions may also include various carbon blacks, clays, silicas, carbonates, oils, resins, waxes and conventional curing agents.
