Abstract: A molded polyurethane body is obtainable by reacting: a) one or more aliphatic polyols having a molecular weight of 450 to 6000 g/mol and a hydroxyl value of 10 to 235; b) with aliphatic and/or cycloaliphatic diisocyanates in an equivalent ratio of diisocyanate to polyol of 1.2:1.0 to 16.0:1.0; c) with diols as chain lengthening agents having a molecular weight of 60 to 450 g/mol, the NCO index formed from the quotient, which is multiplied by 100, of the equivalent ratio of isocyanate groups to the sum of the hydroxyl groups of polyol and chain lengthening agents lying within a range of 90 to 105; and d) with an at least bifunctional reaction component, which is suitable for subsequent cross-linking.

Abstract: The invention relates to a contact adhesive based on a polyurethane of at least one diisocyanate and at least one low molecular weight polyethylene glycol, the polyethylene glycol having a molecular weight of up to 2,000 and the polyurethane having a degrees of crystallization of less than 20%. The contact adhesive can be applied from the melt or from an aqueous solution or dispersion. Surprisingly, it is suitable not only for polar plastic surface, but above all for PE and PP surfaces and of course for paper. Accordingly, the contact adhesive is preferably useful for applying paper labels to PE bottles.

Abstract translation: 本发明涉及一种基于至少一种二异氰酸酯和至少一种低分子量聚乙二醇的聚氨酯的接触粘合剂，聚乙二醇具有高达2,000的分子量，聚氨酯具有小于20％的结晶度， 。 接触粘合剂可以从熔体或水溶液或分散体施加。 令人惊讶的是，它不仅适用于极性塑料表面，还适用于PE和PP表面，当然也适用于纸张。 因此，接触粘合剂优选用于将纸标签应用于PE瓶。

Abstract: A description is given of polyisocyanates of the formula I in which R and R′ are identical or different and are alkyl groups having 1-4 carbon atoms and n is on average from 1.5 to 5 and also of a process for preparing these polyisocyanates in which a polyamine of the formula II in which R, R′, and n are as defined above, is reacted with phosgene. The new polyisocyanates are suitable for producing crosslinked polyurethanes from reaction mixtures with low solvent content and for producing coating compositions or adhesives. Also described are the coating compositions and adhesives, and their use.
