Abstract: An alkyd surfactant which is effective in emulsifying alkyd resins is formed by copolymerization of at least one monomer having a hydrophilic group, at least one ethylenically unsaturated fatty acid or ester, and optionally, at least one polyol, and has a low degree of branching. Stable alkyd emulsions are formed by emulsification of alkyd resins with the alkyd surfactant. Since the alkyd surfactant has ethylenically unsaturated hydrophobe groups which can react with the alkyd resin during curing, the alkyd surfactant is not subject to migration, blooming or leaching from cured coatings.

Abstract translation: 通过至少一种具有亲水基团的单体，至少一种烯键式不饱和脂肪酸或酯和任选的至少一种多元醇的共聚合，并且具有低支化度，形成了对乳化醇酸树脂有效的醇酸表面活性剂。 醇酸树脂与醇酸树脂表面活性剂乳化形成稳定的醇酸乳液。 由于醇酸树脂表面活性剂具有可在固化过程中与醇酸树脂反应的烯属不饱和疏水基团，所以醇酸表面活性剂不会被固化涂料迁移，起霜或浸出。

Abstract: The present invention provides a multicomponent composition that is substantially isocyanate-free and comprises a polycarbamate as a first component having a filler, pigment, extender or matting agent and a second component containing an acidic catalyst an alkanol having one OH group, a polyaldehyde and an acetal or hemiacetal of the polyaldehyde. The compositions are shelf stable and useful as two components and avoid problems caused by combining the catalyst with any filler, pigment, extender or matting agent.

Abstract: The present invention provides substantially isocyanate-free multicomponent compositions useful in making rapid dry automotive primer compositions and coatings, the compositions having a % PVC of from 20 to 60, or preferably, from 25 to 50, and comprising one or more pigment, extender or filler, one or more a) polycarbamates from alkyd polyol or acrylic polyol and one or more b) a polyaldehydes or the acetal or hemiacetal thereof as a second component. The multicomponent compositions cure quickly at a temperature of from 0° C. to less than 80° C. to form a crosslinked polyurethane which dries to enable sanding after only 15 to 45 minutes.
