  • Publication number: 20230056108
    Abstract: The invention relates to a water-in-oil coating composition comprising a water phase emulsified in a non-aqueous liquid phase, wherein the non-aqueous phase comprises an autoxidizable binder and wherein an inorganic first salt and an organic second salt are dissolved in the water phase, wherein the inorganic first salt has a solubility in water of at least 100 grams per liter as determined at 20° C., and a solubility in the non-aqueous phase of less than 1.0 grams per liter as determined at 20° C., and wherein the second salt is an organic salt of an alkali or alkaline earth metal, and wherein the coating composition comprises a primary drier. The invention further relates to a substrate coated with a coating deposited from such water-in-oil coating composition.

  • Patent number: 8053519
    Abstract: Coating composition comprising an alkyd having at least 20% by weight of vinylic building blocks and having an oil length below 65%. The weight ratio non-vinylic:vinylic groups is between 1:1 and 4:1, preferably between 1.5:1 and 3:1. The vinylic groups include styrene and (meth)acrylate groups. The ratio of styrene:(meth)acrylate groups is between 0.5:1 and 4:1, preferably between 1.5:1 and 3:1. The vinylic groups show low polarity. The Mw is below 10,000. The oil length is above 45%. The coating composition can be water borne or solvent borne. The alkyd according to the invention allows formulation of solvent borne coatings a volatile organic content below 300 g/l.

  • Patent number: 6476183
    Abstract: Coating composition and its use in a one-pot system. The coating composition comprises: an oxidatively drying polyunsaturated condensation product, such as an alkyd, having pendant groups in an amount of more than 20% by weight of the condensation product, the pendant groups comprising unsaturated CC bonds; a polythiol having two or more SH-groups; a siccative. The equivalence ratio of thiol functional groups to unsaturated CC bonds being less than 0.3, preferably between 0.01 and 0.25. The coating composition comprises 1-30 wt-%, preferably 3-20 wt-%, of thiol compounds, related to the total weight of solid resin. The coating composition further comprises a drying accelerating complexing agent, preferably 2,2′-bipyridyl or 1,10-phenantroline.

  • Publication number: 20020122947
    Abstract: Coating composition comprising one or more compounds having functional groups which are reactive to olefinically unsaturated bonds, and a citraconimide functional compound, e.g., benzyl citraconimide, octyl citraconimide, or methoxy propyl citraconimide and/or an itaconimide functional compound as a reactive diluent. The reactive diluents are particularly suitable for use in oxidatively drying coating compositions, such as alkyd based coatings, or coating compositions which are curable by radical copolymerization.
