Latest Patents

Ryer holds a patent for a "Self-crosslinking alkyd dispersion." This invention involves producing a coating composition by forming an aqueous dispersion of a crosslinking agent and a resin. The resin comprises the reaction product of an alkyd polymer, an optional surfalkyd, diacetone acrylamide, another acrylate monomer, and optionally aromatic monomers. The reaction product is neutralized with either ammonia or an amine. The resulting coating exhibits several desired properties, including rapid dry time, good tannin blocking, resistance to dirt, hot box stability, and exterior durability. Additionally, these coatings provide improved crosslinking compared to those not neutralized with an amine or ammonia and/or not containing a surfalkyd.
