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.

Abstract: A crosslinkable composition, a coating made therefrom, a process for producing a coating with reduced odor, and a method of reducing the odor of a coating.

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 a coating composition, a process for producing the same, one or more coating layers derived therefrom, and articles comprising one or more such coating layers. The coating composition according to the present invention comprises: (a) from 10 to 90 percent by weight of an aqueous, high-solid, solvent-free alkyd dispersion comprising: (i) from 40 to 70 percent by weight of one or more alkyds based on the total weight of the dispersion, wherein each said one or more alkyds has an acid value of less than 20 and a molecular weight (Mn) in the range of greater than 1000 Dalton; (ii) from less than 10 percent by weight of one or more surfactants, based on the total weight of the dispersion; and (iii) from 30 to 55 percent by weight of water, based on the total weight of the dispersion; wherein said aqueous, high-solid, solvent-free alkyd dispersion has an average particle size diameter in the range of from 0.

Abstract: The present invention generally relates to a foaminess characterization method for characterizing liquid foams and defoamers and a foam generation method for generating the liquid foams.

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.
