UV Curable Low Surface Energy Coatings for Fouling Release and Anti-Graffiti Applications
Coatings are solvent, water, and acrylate free, eliminating health hazardsassociated with acrylates. Low cost of manufacturing due to low levels of siloxane used. Does not suffer from oxygen inhibition
This invention relates to the synthesis of siloxane-modified unsaturatedpolyester oligomers, blending the oligomers with vinyl ethers and aphotoinitiator, and curing the formulation to form a coating that has lowsurface energy. A monohydroxy, a telechelic, and a dihydroxy terminatedPDMS is used for unsaturated polyester synthesis, which is then UV-cured withtriethyleneglycol divinylether as the reactive diluent. These coatings aresolvent-free and can be crosslinked within a few minutes.
