Latest Patents
Katchko holds a patent for 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 consists of an aqueous emulsion containing water with suspended copolymer particles made from monoethylenically unsaturated monomers. These monomers include a hydroxy-functional monomer with a hydroxy number of at least about 20. The remaining monomers contribute to a water-insoluble polymer with a glass transition temperature ranging from about -20°C to about 50°C. The emulsion maintains a pH greater than about 2.5, ideally between 4.0 and 7.0, and utilizes a stoichiometric deficiency of an aminoplast cross-linking agent for curing. An acid curing catalyst is uniformly distributed within the size to expedite the curing process.
