Invention Summary

sucrose soyate

Scientists working at NDSU have discovered a way to make vinyl-block bio-based carboxylic acid crosslinkers for epoxy resins that are particularly useful for vegetable oil based epoxy resins. The resulting coatings have an excellent combination of hardness, flexibility, adhesion, and solvent resistance.

Benefits

  • Final thermoset is a 100% Bio-based system
  • Easy solvent-free synthesis
  • Clear, colorless resin
  • Low viscosity
  • Commercially available inputs
  • Thermosets have high crosslink density, good hardness, excellent adhesion

Applications

  • Coatings
  • Adhesives
  • Composites
  • Thermoset materials
