AQUEOUS ALKYD DISPERSIONS WITH IMPROVED APPLICATION PERFORMANCES IN TERMS OF RESISTANCE TO BLOCKING AND YELLOWING, HARDNESS DEVELOPMENT AND SHINE
The present invention relates to aqueous alkyd resin dispersions comprising a) a short oil alkyd resin comprising, in its fatty acid component a1), at least one polyunsaturated fatty monoacid a11) having at least two unsaturations per molecule and comprising at least 35% by weight of a monoacid a111) having conjugated unsaturations, the content by weight of said fatty monoacid a111), with respect to said alkyd resin, being at least 5%, preferably from 5% to 40% and more preferably from 5% to 35%, and b) at least one anionic phosphate surfactant. The invention also covers a preparation process and its use in decorative coatings. The coatings based on these aqueous dispersions exhibit improved performance qualities in resistance to blocking and yellowing, in development of hardness and in gloss.

Tung oil-based non-lapping water-compatible wood stain
Water-based stains are based on an oil-in-water emulsion having a binder that includes, consists of, or consists essentially of drying oil combined with a non-aqueous polymer dispersion. The compositions can be tinted using traditional water-based pigment dispersions, yet the overall hydrophobicity results in minimal interaction with the polar cellulosic structure of wood.

CYCLIC ETHER- AND HYDROXYL-CONTAINING COMPOSITIONS USEFUL FOR PRODUCING FAST DRY ALKYD POLYMERS AND METHODS FOR MAKING SUCH CYCLIC ETHER- AND HYDROXYL-CONTAINING COMPOSITIONS
An alkyd polymer composition for fast-drying, low VOC applications is provided. The alkyd polymer incorporates a minimum required level of a cyclic ether- and hydroxyl-containing composition formed from a sugar alcohol during the alcoholysis step while synthesizing the alkyd polymer. The disclosure also relates to the cyclic ether- and hydroxyl-containing composition which must have a minimum required level of cyclic ether structure incorporated therein in order to produce a sufficiently fast-drying alkyd polymer. Methods of making the cyclic ether- and hydroxyl-containing composition and the alkyd polymer comprising, as polymerized units, the cyclic ether- and hydroxyl-containing composition and a poly acid and/or an anhydride compound, as well as an optional polyol, other than the sugar alcohol, are also provided. Also provided is a 13 C NMR method of characterizing the necessary minimum required level of cyclic ether ring structure in the cyclic ether- and hydroxyl-containing composition and the alkyd polymer formed therefrom.
