Abstract: A lacquer binder contains (a) a non-aq. dispersion of a copolymer contng. COOH and/or OH gps., (b) aminoplast soluble in (cyclo)aliphatic hydrocarbons and (c) opt. an acid hardening catalyst. The compsn. is easily prepd. it gives thick, hard, glossy coatings, resistant to solvents and chemicals, after baking. The aminoplast may be present during prepn. of the copolymer dispersion. The coating is used on the usual substrates for baking lacquers, e.g. glass, ceramics and metals, esp. on iron or steel sheet in the automobile industry.

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.

Abstract: The invention relates to a process for the preparation of optionally foamed polyurethanes by reacting organic polyisocyanates with relatively high-molecular-weight organic polyhydroxyl compounds in the presence of guanidines and/or thioureas of the formula in which X is sulphur or an =NH group, and n is a number from 2 to 6, as catalyst and optionally blowing agents, chain extenders, assistants and additives.

Abstract: The process involves the reaction of organic polyisocyanates, polyols, optionally substituted aliphatic and/or cycloaliphatic monoamines in an amount of from 0.1 to 10 parts by weight per 100 parts by weight of polyol, and/or optionally substituted aromatic monoamines in an amount of from 0.1 to 4 parts by weight per 100 parts by weight of polyol, and, if desired, chain extenders or crosslinking agents, in the presence of blowing agents, catalysts, assistants and, if desired, additives.
