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.
