Abstract: LACQUERS SUITABLE FOR MOTOR VEHICLES AND THE LIKE ARE PREPARED FROM MIXTURES OF POLYACRYLATE RESINS CONTAINING HYDROXYL GROUPS AND N-ALKOXYMETHYLURETHANES. THE ALKOXYMETHYTLURETHANES BRING ABOUT THE CROSS-LINKING OF THE POLYACRYLATE RESIN. IN ADDITION TO THE ABOVE MENTIONED INGREDIENTS, MELAMINE FORMALDEHYDE OR UREA FORMALDEHYDE RESINS MAY BE USED JOINTLY WITH THE N-ALKOXYMETHYLURETHANES.

Abstract: This invention relates to bonding coats and top coats made of aliphatic, segmented polycarbonate-polyurea elastomers for coating textile substrates. The coats are applied to the substrates from their solutions by the reverse roll coating process. The coating used has the advantage of providing resistance to hydrolysis, light fastness, unlimited pot life and can be prepared with inexpensive and physiologically harmless solvents. The synthetic leather has a high abrasion resistance, high folding strength, high flexibility in the cold and resistance to alcohol.

Abstract: A lacquer polyisocyanate (I) based on modified 1-isocyanato-3, 3-5-trimethyl-5-isocyanato-methylcyclohexane (II) contains (a) 5.7-17 wt.% of trimerised isocyanate gps. in the form of isocyanurate gps., (b) 10.4-29 wt.% of blocked NCO gps., and (c) 2.1-16 wt.% of free NCO gps., all without including the wt. of the blocking agent. The use of (I) in heat-crosslinkable, 2-component polyurethane powder lacquers is claimed. (I) is a stable solid with a low content of by-prods. The optimum melting range can be obtd. by choice of the degree of trimerisation and blocking. The baking temp. of the lacquers is lower than with completely blocked binders. -

Abstract: Polyurethane urea elastomers with novel dissolution behavior and which are synthesized from polycarbonate macrodiols, diisocyantes and diamines and which can be prepared and dissolved in aqueous solvents. These elastomers have the advantage of being less of a physiological hazard, more resistant to common solvents and require less emulsifiers and dispersion aid.
