Title: Frank J Hahn: Innovator in Coating Technologies
Introduction
Frank J Hahn is a notable inventor based in Wilbraham, MA (US). He has made significant contributions to the field of coating technologies, holding a total of 4 patents. His work focuses on innovative resin compositions that enhance the performance and application of coatings.
Latest Patents
Hahn's latest patents include advancements in articles coated with an aminoplast polyfunctional resin composition. This invention involves a thermoset reaction product of a liquid resin composition that comprises a reactive polymer and an N,N'-bis(alkoxymethyl)uron. The reactive polymer contains functional groups such as hydroxyl and carboxyl, with a molecular weight ranging from 300 to 5000. The uron ether serves as a cosolvent, allowing the solution to be applied as a coating without significant amounts of conventional solvents. The interaction between the polymer and the uron ether, when promoted by heat in the presence of an acid catalyst, enables the uron ether to act as a crosslinking agent for the polymer.
Another significant patent involves trimellitic acid monoesters of styrene allyl alcohol copolymers. In this invention, carboxylated styrene allyl alcohol copolymers are prepared through the reaction of trimellitic anhydride and a hydroxy copolymer under controlled conditions. This process minimizes polyester formation and results in copolymers that can be utilized in adhesive and surface coating applications.
