Abstract: An aqueous or water-borne precursor for forming an anti-fouling heterophasic thermoset polymeric coating is provided. The precursor includes a fluorine-containing polyol precursor having a functionality greater than about 2 that forms a branched fluorine-containing polymer component defining a continuous phase in the anti-fouling heterophasic thermoset polymeric coating. The precursor also includes a fluorine-free precursor that forms a fluorine-free component present as a plurality of domains each having an average size of greater than or equal about 100 nm to less than or equal about 5,000 nm defining a discrete phase within the continuous phase in the anti-fouling heterophasic thermoset polymeric coating. A crosslinking agent and water are also present. An emulsifier may also be included. Methods of making anti-fouling heterophasic thermoset polymeric coatings with such precursors are also provided.

Abstract: An aqueous or water-borne precursor for forming an anti-fouling heterophasic thermoset polymeric coating is provided. The precursor includes a fluorine-containing polyol precursor having a functionality >about 2 that forms a branched fluorine-containing polymer component defining a continuous phase in the anti-fouling heterophasic thermoset polymeric coating. The precursor also includes a fluorine-free precursor that forms a fluorine-free component present as a plurality of domains each having an average size of ≥about 100 nm to ≤about 5,000 nm defining a discrete phase within the continuous phase in the anti-fouling heterophasic thermoset polymeric coating. A crosslinking agent and water are also present. An emulsifier may also be included. Methods of making anti-fouling heterophasic thermoset polymeric coatings with such precursors are also provided.

Abstract: An aqueous precursor liquid for forming an anti-fouling heterophasic thermoset polymeric coating is provided. The precursor liquid includes a first fluorine-containing polyol precursor having a functionality >about 2 that forms a fluorine-containing polymer component defining a first phase in the coating. The precursor liquid also includes a second precursor that forms a second component present as a second phase. The first phase can be a continuous phase and the second phase can be a discrete phase, or the second phase can be the continuous phase and the first phase can be the discrete phase. The discrete phase includes a plurality of domains each having an average size of ≥to about 500 nm to ≤to about 25,000 nm. A crosslinking agent, water, and optional acid or base are also present. Methods of making anti-fouling heterophasic thermoset polymeric coatings with such precursors are also provided.
