摘要:
Water-dispersible (including water-soluble) salts of water-soluble amines with the anionic products formed by reacting at 200.degree. C. to 250.degree. C. a substantially neutral ester of a C.sub.14-20 saturated fatty alcohol with an ethylene-dicarboxylic acid which has been reacted with about 1/7 to 1/35 of its weight of a ethylenedicarboxylic compound of acidic character (for example maleic acid) are efficient agents for inhibiting the deposition of pigment in pigmented aqueous lacquers. Organic solutions of the salts are storage-stable. The salts can be incorporated into the lacquer during formulation of the lacquer or at a later point.

Mortars and plasters containing additives which are alcohols having from 8 to 72 carbon atoms adsorbed on solid supports, and processes for the preparation of the additives.
摘要:
The process of controlling foam in a foam-generating system by adding to the system a foam-inhibiting effective amount of a block copolymer containing alkylene oxide units obtained by reacting a homopolymer or copolymer of alkylene oxides with a diisocyanate or a dicarboxylic acid derivative containing 2 to 44 carbon atoms.
摘要:
Provided are thickeners based on an aqueous preparation of nonionic, water-dispersible or water-soluble polyurethanes, to their production and to their use. The nonionic, water-dispersible or water-soluble polyurethanes are obtainable by reaction of polyfunctional isocyanates with polyether polyols, monohydric alcohols and, if desired, polyhydric alcohols, wherein the monohydric alcohols contain at least one other polar group. Also provided is a process for the production of such thickeners. The thickeners are particularly suitable for thickening emulsion paints.
摘要:
Air-drying lacquer binder of a ring-opening product of (I) an epoxidized polyoctenylene or cylco-octene-cycloene copolymer having an average molecular weight of from 600 to 3000 and (II) one or more of (a) an unsaturated carboxylic acid containing from 6 to 22 carbon atoms, (b) an alcohol containing from 2 to 6 hydroxy groups (c) a hydroxyalkylamine containing at least one hydroxyalkyl group, the hydroxy groups of the alcohols (b) and the hydroxyalkylamines (c) being esterified with an unsaturated carboxylic acid containing from 6 to 22 carbon atoms to an OH number of less than 25, and wherein the ring opening product has an average molecular weight of from 1500 to 10,000 and an acid number of from 0.1 to 20. The invention also relates to a process for producing this lacquer binder and to its use in high-solids lacquer systems.
