His innovative work has led to the creation of a patented process that enhances the quality and performance of latex paints.

Latest Patents

Gunning holds a patent for "Polyester granules and process." This invention involves the preparation of aqueous slurries of vesiculated cross-linked polyester resin granules. These granules exhibit a shrinkage of less than 5% upon drying, achieved through a double-emulsion process. The process utilizes polyamine with a pKa value of 8.5-10.5, at a concentration of 0.3 to 1.4 amine groups per carboxyl group of the polyester. The acid value is limited to 10-45 mg KOH per gram. These granules serve as opacifying matting agents in latex paints, effectively preventing cracking at high film builds.
