Polymer-base painted resin cured unsaturated elastomeric substrates

阅读：209发布：2024-01-17

专利汇可以提供Polymer-base painted resin cured unsaturated elastomeric substrates专利检索，专利查询，专利分析的服务。并且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.，下面是Polymer-base painted resin cured unsaturated elastomeric substrates专利的具体信息内容。
