Invention Summary

Thermosetting polymers and composites are widely used in industry due to their low density, good mechanical properties, low cost, and dimensional stability. However, most resins are synthesized primarily using petroleum-based chemicals. Due to current environmental concerns and the limit of fossil feedstocks, the industry is suffering from increasing costs and environmental regulations. Webster et al. have developed novel epoxy resins synthesized from the reaction between vanillin and diamines to form a Schiff base. Vanillin can also be glycidated to form another bio-based resin. Vanillin is derived from the depolymerization of lignin, an abundant aromatic bio-polymer currently treated as a waste product in pulp and paper industries, and therefore expands the use of traditionally wasted materials.


  • Low-cost bio-based resin
  • Do not contain bisphenol-A
  • Provides another use for a waste product
  • Applications in coatings, composites, and adhesives


The technology includes a vanillin Schiff base compound, which may or may not be glycidated, a method of preparing a bio-based epoxy resin from these compounds, and a curable coating composition of these compounds.


This technology is patent pending with fully preserved PCT patent rights and is available for licensing/partnering opportunities.
