A polyaddition compound and/or a salt thereof is obtainable by the reaction of epoxy resin based on at least one diglycidyl ether of Formula (I) wherein R=a divalent aliphatic or monocyclic aromatic or bicyclic aromatic radical or mixtures thereof; with at least one polyether alcohol of Formula (II)R-[OEt]-[OPr]-[OBu]-[OSO]-OH&#x2003;&#x2003;Formula (II)wherein R=independently identical or different, linear or branched, optionally aromatic hydrocarbyl radicals having 1 to 18 carbon atoms, [OEt]=ethylene oxide radical, [OPr]=propylene oxide radical, [OBu]=butylene oxide radical, [OSO]=styrene oxide radical, n=0 to 100, m=0 to 50, s=0 to 20, and r=0 to 3, with the proviso that n+m+s+r=3-103, and with at least one compound containing at least one functional group selected from sulfate groups, sulfonate groups, carboxylate groups and phosphate groups.

Wetting agents and dispersants having rheological character

Solventborne alkyd paint composition containing a universal colorant of organic pigment or inorganic pigment, a solventborne alkyd base paint and a fatty acid amidoamine, where the fatty acid amidoamine is the condensation product of a fatty acid or their corresponding ester or fatty oil and a polyamine, the polyamine is an aliphatic polyamine having an amine functionality of at least 2, and the polyamine contains at least one primary amine group and at least one tertiary amine group.

Compatibilizer for universal colorant in solventborne alkyd paints

A dispersing resin for conventional solventborne pigment preparations having a low to very low proportion of volatile organic substances is provided. Further provided are solventborne coating materials containing the dispersing resin. Uses include paints, varnishes, adhesives, inks or printing inks, and compositions for coloring of plastics. The pigment preparations produced with these resins are free of yellowing, stable to weathering, of low viscosity and intensely colored.
