[0229] Coating solutions having the compositions reported in Table 2 were prepared by mixing 3% of I2 photoacid generator (prepared as a 10% solids solution in S2) with polymer solutions P1-P7. The coating solution was applied to polyester (PET) film (E.I. du Pont de Nemours and Co.) using a wire wound rod (RD Specialties, Webster, New York). MELINEX 618) on the primer surface. Wire rods used were #3 (nominal wet film thickness = 6.9 microns), #6 (nominal wet film thickness = 13.7 microns), #12 (nominal wet film thickness = 27.4 microns). The coated film was dried in an oven set at 90° C. for 1 minute, and then dried using a UV light processor (Fusion UV Systems, Inc., Gaithersburg, MD) equipped with an H-bulb at 100% bulb power. (LIGHT-HAMMER 6UV from Fusion UV Systems Inc., Gaithersburg, Maryland)) was allowed to cure under a nitrogen atmosphere. The film was cured using a UV processor with 2 passes at a line speed of 30 ft / min (9.1 m / min).

Abstract

Curable antifouling compositions include fluorinated polymers that contain a perfluoropolyether group, a poly(alkyleneoxide) group, a hydrolyzable silane group and a cationic curative. The curable antifouling compositions can be applied on a surface of a substrate, and at least partially cured to provide an article with antifouling properties.

Description

technical field [0001] The present disclosure relates broadly to compositions useful for inhibiting biofouling. Background technique [0002] The term "biofouling" refers to the attachment of living organisms to surfaces. Biofouling typically occurs when water-based liquids come into contact with other materials. Biofouling is ubiquitous, but most economically significant for the shipping industry, as high levels of biofouling on ship hulls significantly increases drag and increases fuel consumption. Industrially important implications of biofouling include: maintenance of mariculture, membrane systems (eg, membrane bioreactors and reverse osmosis spiral membranes), and cooling water circulation in large industrial plants and power stations. Biofouling can occur in oil pipelines carrying oils with entrained water, especially those carrying used oils, cutting oils, oils rendered water-soluble by emulsification, and / or hydraulic oils. Other things affected by biofouling inc...
