Latest Patents

Burkhart holds a patent for "Epoxy-urethanes based on copolyesters." This patent describes a process for producing polyester-urethane-epoxy adhesives. The method involves reacting one or more diols with two or more dicarboxylic acids to create a polyester prepolymer. The prepolymer is then chain-extended with an organic diisocyanate to yield a hydroxy-terminated polyester-urethane. This urethane can be capped partially or completely with a dicarboxylic acid or anhydride of dicarboxylic acid. Finally, it is reacted with an epichlorohydrin/bisphenol A-type epoxy resin, resulting in an epoxy polyester-urethane block copolymer. The final product can be crosslinked for use as an adhesive.
