With a total of 8 patents to his name, Plaisance continues to push the boundaries of technology in his industry.
Latest Patents
Among his latest patents is a thermosetting size press composition. This invention involves a thermosetting size that can be applied to paper in a size press and cured at a temperature not exceeding about 280°F for 10 seconds. The composition includes an aqueous emulsion with suspended copolymer particles of monoethylenically unsaturated monomers, which contain a hydroxy-functional monomer. The emulsion is designed to have a pH greater than about 2.5, with a preferred range from 4.0 to 7.0, and utilizes an acid curing catalyst to expedite the curing process.
Another significant patent is for silicone release coating emulsions that stratify when baked. This heat curable aqueous emulsion is designed to deposit a release coating that stratifies, allowing for a more efficient silicone application on surfaces. The emulsion consists of water, a fatty acid or fatty alcohol-containing hydroxy-functional polyester, a cross-linking agent, and at least one silicone that reacts with the hydroxy-functional resin. This innovative approach enhances the effectiveness of silicone coatings.
