Latest Patents

One of Lin's latest patents is titled "Curable system of self-emulsified aqueous epoxy resin and its polymeric hybrids." This invention discloses an anionic, self-emulsified aqueous epoxy resin dispersion that is prepared through a semi-esterification reaction. The process involves the reaction between a dicarboxylic acid anhydride and the secondary hydroxy group of an epoxy resin. The resulting stable aqueous epoxy resin contains both carboxyl and epoxy groups, which are reactive functional groups. Additionally, Lin has developed a "single-pack" curable aqueous epoxy resin system that can be cross-linked at normal temperatures. This system utilizes a compound containing polyaziridine as a cross-linking agent, leading to a novel double cross-linking process.

Another significant patent by Lin is related to a "Uretedione derivative, curable resin composition comprising the same." This invention introduces a novel uretedione derivative that serves as a curing agent for aqueous-based polyurethane. The uretedione derivative contains functional groups that are active toward the amino and carboxyl groups of hydrolyzed polyurethane in an aqueous phase.
