UV Curable Low Surface Coatings
RFT-254
A new type of UV-curable PDMS coating was formulated and characterized in this invention. Preliminary investigations have shown that the surface is hydrophobic and films are softer than that obtained from unmodified polyester. The basis of this invention is in the synthesis of novel unsaturated polyester compositions containing poly-dimethyl-siloxane (PDMS) by mixing these polyesters with co-reactants and photoinitiators, and curing the compounds using either visible or UV light to form coatings having low surface energy. Applications include marine, packaging materials, protective wood coatings, anti-graffiti coatings, easy clean coatings and release coatings. The uniqueness and importance of this invention pertains to its novel siloxane-modied unsaturated polyesters, UV curable technology (so no oxygen inhibition), low siloxane (cost effective), and solvent free nature.
