Abstract

Oppfinnelsen angår en polyuretansammensetning med adhesjonsklebrige egenskaper, en fremgangsmåte for deres fremstilling samt deres anvendelse som adhesjonsklebestoff. For optimering av klebestoffet med hensyn til adhesjon etter flere gangers åpning og lukking av klebeforbindelsen samt med hensyn til migrasjon av skadelige komponenter, foreslås en polyuretansammensetning som kan oppnås ved omsetning av to komponenter A og B, hvorved a) anvendes som komponent A minst en polyuretanprepolymer Al som kan oppnås ved omsetning av minst en polyolkomponent med minst to minst difunksjonelle forskjellige isocyanater og b) som komponent B anvendes et minst difunksjonelt herdemiddel som oppviser pr. molekyl minst to overfor isocyanatgrupper funksjonelle grupper med reaksjonsevne, hvorved forholdet mellom isocyanatgrupper og overfor isocyanatgrupper funksjonelle grupper med reaksjonsevne, er større enn 0,75 og mindre enn 1,15.The invention relates to a polyurethane composition having adhesion-sticking properties, a process for their preparation and their use as adhesion adhesives. In order to optimize the adhesive with respect to adhesion after several times opening and closing of the adhesive compound and with regard to migration of harmful components, a polyurethane composition obtainable by the reaction of two components A and B is proposed, where a) is used as component A at least one polyurethane prepolymer Al which can be obtained by reacting at least one polyol component with at least two at least difunctionally different isocyanates and b) as component B is used a least difunctional curing agent exhibiting per unit weight. molecule at least two to isocyanate groups functional reactivity groups, whereby the ratio of isocyanate groups to isocyanate functional reactivity groups is greater than 0.75 and less than 1.15.
