Abstract: To prepare light-stable polyurethane integral skin foams, especially soft integral foams, aliphatic and/or cycloaliphatic polyisocyanates, both categories preferably containing urethane groups and/or biuret groups, are reacted with polyols in the presence of blowing agents and of a synergistic catalyst combination comprising an alkali metal hydroxide, alkali metal alcoholate, alkali metal phenolate, alkali metal salt of a weak acid and/or hexahydrotriazine derivative and an organic tin, zinc and/or iron(II) compound, in the presence or absence of assistants and adjuvants. The preferred catalyst combination is tri-(dimethylaminopropyl)-s-hexahydrotriazine and dibutyl-tin dilaurate.

Abstract: The subject of the invention is constituted by moisture-curing, storage-stable single-component polyurethane systems which contain A) a polyurethane prepolymer having an NCO content of 1 to 5 wt.%, B) a dialdimine of the formula in which R is an alkylene radical having 2 to 10 C atoms, an alkylene radical, having 4 to 10 C atoms, containing oxygen and/or an N-alkyl group as bridge member, a cycloalkylene radical having 6 to 15 C atoms or an arylene radical having 6 to 21 C atoms, and C) an aromatic and/or aliphatic carboxylic acid or toluene-sulphonic acid. The polyurethane systems are used as coating, covering, sealing, grouting, puttying and bonding compositions.

Abstract: A process for bonding lignocellulose raw materials using an isocyanate group-containing urethane-modified diphenylmethane diisocyanate mixture having a viscosity of 120 to 1000 mPas at 25 DEG C. and an isocyanate content of 15 to 33.6 percent by weight which is obtained by reacting a diphenylmethane diisocyanate mixture containing 10 to 75 percent by weight of 2,4'-diphenylmethane diisocyanate with 0.05 to 0.5 hydroxyl equivalents of a polyol per equivalent isocyanate group.

Abstract: The invention relates to polyurea-polyol dispersions with a long shelf life which contain a) from 2 to 35 % by weight, based on the entire dispersion, of a polyurea prepared from modified aliphatic and/or cycloaliphatic polyisocyanates and aliphatic amines and/or optionally substituted monoaminobenzenes or modified aromatic polyisocyanates and aliphatic amines and, b) from 98 to 65 % by weight, based on the entire dispersion, of a bifunctional to hexafunctional polyol having a hydroxyl number of from 20 to 600. The dispersions are prepared by in-situ reaction of the modified polyisocyanates with aliphatic amines and/or monoaminobenzenes in polyols, have, at a polyurea content of 10 % by weight, a viscosity at 25 DEG C of from 1000 to 2500 mPa.s and a clear point of from 100 to 300 DEG C and are particularly suitable for the production of polyurethane foams.
