20110046257 | UV-CURABLE LOW SURFACE ENERGY COATINGS - The invention provides an improved unsaturated polyester prepared from the polycondensation of unsaturated diacid monomers or unsaturated acid anhydride mononers and polyol monomers and. optionally, one or more saturated aliphatic or aromatic diacid monomers or anhydride monomers thereof. The improvement comprises 0.5 to 50 weight percent, based on the total monomer weight, of an hydroxyalkyl-functional siloxane of formula (1) below. The invention also relates to a UV curable coating formulation containing a siloxane-functional unsaturated polyester resin, a vinyl ether functional diluents and a photoinitiator. The invention further provides a method of preparing an article with a low-surface energy coating. According to the method, at least one surface of an article with a coating formulation of the invention; and the coating is then cured as described above with UV light to form a low-surface energy coating on the surface. The invention also relates to articles having a low-surface energy coating according to the invention. | 02-24-2011 |
