    • A solventless adhesive is disclosed, the adhesive comprising an isocyanate component comprising at least one isocyanate prepolymer that is the reaction product of reactants comprising at least one isocyanate, at least one polyol, and a branched alkane diol, and a polyol component comprising at least one polyol and a branched alkane diol. The branched alkane diol can comprise a single side alkyl chain, such as 3-methyl-1, 5-pentanediol, 2-methyl-1, 3-propanediol, and combinations thereof. Further, a method for forming a laminate is disclosed, the method comprising forming a solventless adhesive composition comprising a branched alkane diol, applying a layer of the adhesive composition to a surface of a film, bringing the layer into contact with a surface of another film to form a laminate, and curing the adhesive composition. Still further, a laminate formed by the method is disclosed.
    • 公开了一种无溶剂粘合剂,所述粘合剂包含异氰酸酯组分,所述异氰酸酯组分包含至少一种异氰酸酯预聚物,所述异氰酸酯预聚物是包含至少一种异氰酸酯,至少一种多元醇和支化链烷二醇的反应物的反应产物, 和包含至少一种多元醇和支链烷二醇的多元醇组分。 支化烷烃二醇可以包含单一侧烷基链,例如3-甲基-1,5-戊二醇,2-甲基-1,3-丙二醇及其组合。 此外,公开了一种用于形成层压体的方法,该方法包括形成包含支链烷二醇的无溶剂粘合剂组合物,将粘合剂组合物层施加到膜的表面,使该层与另一膜的表面接触 以形成层压体,并且使粘合剂组合物固化。 更进一步地,公开了通过该方法形成的层压体。
