    • A water-curable hot melt adhesive system is disclosed. The system uses silane hydrolyzable functionality grafted onto an ethylene polymer component, and a tackifier compatible therewith. The ethylene polymer component is a copolymer of ethylene and a hydrocarbyl ester of an .alpha.,.beta.-ethylenically unsaturated carboxylic acid, and the tackifier component provides the adhesive with sufficient silanol condensation catalytic activity to accelerate water curing. The formulation is applied to a substrate surface as a hot melt at a moderate temperature, and subsequently cured by moisture or in a warm water bath. The invention also embodies structural compositions having glass, metallic or leather surfaces adhered with the adhesive and a method for making structural composites.
    • 公开了一种水可固化热熔粘合剂体系。 该系统使用接枝到乙烯聚合物组分上的硅烷可水解官能团和与其相容的增粘剂。 乙烯聚合物组分是乙烯和α,β-烯键式不饱和羧酸的烃基酯的共聚物,并且增粘剂组分为粘合剂提供足够的硅烷醇缩合催化活性以加速水固化。 该配方在中等温度下作为热熔体施用于基材表面,随后通过水分或在温水浴中固化。 本发明还体现了具有粘合剂的玻璃,金属或皮革表面的结构组合物以及制备结构复合材料的方法。
