UV-Curable Low Surface Energy Coatings for Fouling Release and Anti-Graffiti Applications (RFT-254)

Invention Summary

In the current market, there are several applications for low surface energy and UV curable coatings. Scientists at NDSU have developed a novel polyester composition that combines the two properties. The composition contains a modified siloxane backbone blended with co-reactants, diluents and photo-initiators. The mixing process is solvent-free and the composition can be crosslinked within a few minutes. The mixture can be cured using either visible or ultraviolet (UV) light. The modified backbone can be blended with different co-reactants, the most successful combination in the lab testing was - a monohydroxy, a telechelic, and a dihydroxy terminated PDMS UV-cured with triethyleneglycol divinylether. These coatings are beneficial in a variety of applications such as marine ship hulls, anti-graffiti surfaces, release coatings, and protective wood coatings with easily cleanable surfaces.



  • Coatings are solvent, water, and acrylate free
  • Low surface energy
  • Low manufacturing costs
  • Resistant to Oxygen inhibition
  • Eliminates health hazards associated with acrylates
  • Low levels of siloxane
  • Customizable with different diluents
