Latest Patents

Munneke holds a patent for a "Process for preparation of stable polycarbodiimide dispersions in water, which are free of organic solvents and may be used as a crosslinking agent." This process involves reacting a polyisocyanate in the presence of a carbodiimide catalyst to form a polycarbodiimide. The method includes terminating or chain extending the polycarbodiimide chain by adding a compound containing a hydrophilic group and one or more amine functions. The resulting dispersion is characterized by a pH adjusted to a value between 9 and 14, with a preferred range of 11 to 13. This invention also relates to a coating mixture that includes the polycarbodiimide dispersions as a crosslinking agent and an aqueous resin containing carboxylic acid functions.
