    摘要: The present invention relates to novel waterborne adhesives which are polymerizable by UV light and are capable of being activated by heat, and which particularly display good adhesion to difficult substrates, such as ethylene vinyl acetate copolymers (EVA) with a low vinyl acetate content, or rubber. The invention further provides a novel method in which, after the application of the waterborne adhesive to an article and drying, irradiation with UV light and at the same time or thereafter activation by heat are performed. The adhesive film which is irradiated and activated in this way is then bonded to a further article. The invention also provides the use of the adhesives to make items such as shoes.

    摘要: Hot-sealable coating systems and method for joining surfaces The present invention relates to a hot-sealable coating system, comprising a polyurethane and/or polyurethane-polyurea polymer (I) and an olefin vinyl acetate copolymer (II). The polyurethane and/or polyurethane-polyurea polymer (I) is obtainable by the reaction of (A) at least one diol and/or polyol component, (B) at least one di-and/or polyisocyanate component, (C) at least one component having sulphonate and/or carboxylate groups, (D) mono-, di-and/or tri-amino-functional and/or hydroxyamino-functional compounds (as appropriate), (E) other isocyanate—reactive compounds (as appropriate). The polyurethane and/or polyurethane-polyurea polymer (I) has a glass transition temperature of ≦10 ° C. and the olefin vinyl acetate copolymer (II) has a minimum film forming temperature (white point temperature) of >+40° C. The invention also relates to the use of the coating system and a method for joining surfaces in which the coating system according to the invention is used.
