A shellac-substitute is described herein in the form of an acid-functional polymer or an acid-functional polyester polymer. The acid-functional polyester polymer, among other uses, is suitable for stain-blocking with coating compositions, such as primers, sealants, stain-blocking coating compositions, odor-blocking compositions, and/or varnishes.

Rosin-based polymer for stain-blocking coating compositions

A waterborne coating composition including a novel polymer latex and methods of preparing the polymer latex for the waterborne coating composition. The disclosed polymer latex, when incorporated into the waterborne coating composition, reduces gloss, and achieves a matte appearance without the need for and/or with reduced amounts of traditional inorganic matting additives. In one approach, the polymer latex disclosed herein includes latex particles having a core/shell arrangement configured to not only participate in film formation but also impact surface morphology of dried films to produce the low gloss coatings.

Polymer latex for matte films

A self-crosslinking compound and coating compositions including the same as well as compositions capable of forming a ketone or carbonyl-hydrazide crosslink at ambient temperatures that utilizes a modified latent cross linker capable of forming a polymer networked in an applied coating.
