  • Patent number: 5888602
    Abstract: Flat rubber sheets are joined together at their primed surfaces utilizing an adhesive tape composition which features at least one EPDM rubber and will provide a long-term, water-tight barrier. The adhesive tape composition is a solventless, preformed, tacky composition comprising a) at least one crosslinkable EPDM rubber, b) a filler, either of the reinforcing or semi-reinforcing variety, c) one or more compatible tackifiers, d) a softener, and lastly, e) a cure system for the rubbery polymer. The tape composition itself has excellent ozone, moisture, weathering and heat aging resistance as well as superior low temperature properties.
    Type: Grant

  • Patent number: 5612141
    Abstract: An adhesive tape composition includes a polymer blend comprising at least one EPDM rubber, and preferably three EPDM rubbers in substantially equal amounts, and an adhesive-enhancing polymer selected from the group consisting of polyisoprene, polybutadiene, and ethylene-propylene copolymer and mixtures thereof. The tape adhesive composition further includes at least one tackifying additive compatible with said polymer blend and a sulfur and organic accelerator cure package for said polymer blend, the adhesive composition being devoid of butyl rubber which is found in most other adhesive tape compositions. This composition is seen as providing excellent long-term heat aging, weathering resistance, and low temperature properties as compared to adhesive tape compositions containing butyl rubber. Moreover, the adhesive tape composition provides more surface tack, better "quick-grab", and higher green strength as compared to adhesive tape compositions containing 100 percent EPDM rubber.

  • Patent number: 5409987
    Abstract: A flowable adhesive composition specifically adapted for use in securing rubber sheet material to a substrate surface includes at least one polychloroprene rubber polymer, at least one polymer or copolymer which is comprised primarily of one .or more monoolefins, and a suitable solvent for simultaneously dissolving the polychloroprene and monoolefin based rubbers to form a homogeneous composition which can be applied to the substrate surface and rubber sheet as by pouring, brushing, spraying, rolling, or similar operations.The composition comprises a blend containing at least one polychloroprene rubber and at least one monoolefin based polymeric elastomer. The rubber adhesive composition of the invention exhibits good initial bond strength and excellent resistance to creep, while simultaneously demonstrating the ability to retain good adhesive properties upon repeated exposure to moisture.

  • Patent number: 4851462
    Abstract: A solvent based contact adhesive suitable for bonding cured EPDM membranes is disclosed. The adhesive includes a crosslinked halogenated butyl rubber, a low molecular weight, high softening point, thermoplastic aliphatic-type-based hydrocarbon resin and at least one organic solvent employed as a dispersion medium for the crosslinked halogenated butyl rubber and the resin. The disclosed adhesive exhibits superior heat aging and hot water immersion properties which are significant characteristics in roof applications.
