Phytic acid coating - Phytic acid binding agent

Ref.-No. 6422

Keywords: Sustainable chemistry, corrosion protection, binders, phytic acid paints, environmental technology

A new invention from the Hochschule Niederrhein encompasses an environmentally friendly binding agent consisting of alkyl phytic acid oligomers, which can be thermally combined with such substances as epoxy resins (as amine substitutes) and OH-functional binding agents (as crosslinkers).

Competitive Advantages

  • Simple synthesis
  • Sustainable chemistry
  • Environmentally friendly products
  • “adjustable” properties

Commercial Opportunities

Sustainable binding agents from renewable raw materials are important for sustainable coating applications. Phosphorus is not a sustainable raw material, but exhibits excellent corrosion protection effects in the form of phosphates in organic compounds. Synthesizing a phytic acid-based binding agent produces the first sustainable phosphorus source for integrating phosphate groups into organic binding agents. These binding agents were combined with OH acrylates and epoxies to create stable coatings based on sustainable raw materials. The binding agents also have outstanding dispersion properties, so that they can be used to grind pigments without any dispersion additives.

Current Status

A patent application has been submitted to the German Patent and Trade Mark Office. Within the priority year, a PCT application was also submitted. We are offering interested companies the opportunity to license and refine the technology in collaboration with the inventors and the Hochschule Niederrhein.
