    • An epoxy resin composition comprising (a) a cyclopentadiene-type hydrocarbon resin having a hydroxyl value of 100 to 300 obtained by copolymerizing a cyclopentadiene-type monomer and a hydroxyl-containing monolefinic monomer at elevated temperatures, (b) a polyol selected from the group consisting of epoxy resins containing at least two hydroxyl groups in the molecule and epoxy resin derivatives containing at least two hydroxyl groups in the molecule and obtained by the reaction of epoxy resins with alkanolamines, and (c) an isocyanate-type curing agent. The compositions have improved low temperature curability, acid resistance and water resistance while retaining the various desirable properties of epoxy resins such as chemical resistance and oil resistance, and which when used as paints, exhibit improved adhesion to an adherend and improved re-coating adhesion to the film formed thereon.
    • 一种环氧树脂组合物,其包含(a)通过在升高的温度下使环戊二烯型单体和含羟基的单烯属单体共聚获得的羟值为100〜300的环戊二烯型烃树脂,(b)选自 由分子中含有至少两个羟基的环氧树脂和分子中含有至少两个羟基并通过环氧树脂与链烷醇胺的反应获得的环氧树脂衍生物和(c)异氰酸酯型固化剂组成。 该组合物具有改善的低温固化性,耐酸性和耐水性,同时保持环氧树脂的各种所需性能如耐化学性和耐油性,并且当用作涂料时,显示出对被粘物的改善的粘附性和改善的涂覆粘附性 在其上形成膜。
