The present invention pertains to a fluoropolymer hybrid organic/inorganic composite, to a process for manufacturing said fluoropolymer hybrid organic/inorganic composite and films and membranes thereof and to uses of said fluoropolymer hybrid organic/inorganic composite and films and membranes thereof in various applications.

The invention relates to an aqueous fluoropolymer coating composition for direct application to glass without the need for pre-treatment of the glass surface. The coating composition can also be used with other non-porous and porous substrates. The fluoropolymer coating contains a hydroxyl-functional fluoropolymer, and polyisocyanates. Preferably the coating composition also contains a water-dispersible hydroxyl functional polyurethane. The coating composition may exist as a 1-pack or a multi-pack coating system. The coating has excellent wet adhesion to glass, good weathering, chalking resistance, chemical resistance, and dirt pickup resistance.

The invention relates to an intertwined multilayer primer/fluoropolymer coating on the glass substrate. The final coating has excellent wet adhesion to glass, good weathering, durability, chalking resistance, chemical resistance, and dirt pickup resistance. The coating is an environmentally friendly aqueous, fluoropolymer coating composition. The coating process involves applying a polyurethane primer to the glass substrate, and partially, but not completely crosslinking this primer coating. An aqueous hydroxyl-functional fluoropolymer coating is then applied to the partially cross-linked primer coating, and the coating allowed to fully cure. The invention also relates to the intertwined multilayer primer/fluoropolymer coating on the glass substrate. The final coating has excellent wet adhesion to glass, good weathering, durability, chalking resistance, chemical resistance, and dirt pickup resistance.

A curable composition includes a blocked isocyanate in which an NCO group of an isocyanate compound having a H.sub.6XDI skeleton is blocked by a blocking agent having an OCCHCO skeleton, a curable functional group-containing fluorine polymer, and an alkoxysilane having a functional group including at least one element of a group 15 element to a group 16 element of the periodic table (excluding oxygen). In the curable composition allowing a titanium oxide to be contained, the molar ratio of the curable functional group to the NCO group is 0.5 to 10; the content ratio of the alkoxysilane with respect to 100 pans by mass of the total amount of the blocked isocyanate and the fluorine polymer is 0.2 to 8 parts by mass; and the content ratio of the titanium oxide with respect to 100 parts by mass of the fluorine polymer is 0 to 200 parts by mass.

Methods of protecting a propeller include applying an inner polymer layer onto a propeller. The inner polymer layer is impregnated with a biologically active chemical substance that inhibits biofouling-induced chemical, biological, and bio-proliferative damage and that does not chemically or galvanically interact with a material of the propeller. An outer polymer layer is applied onto the inner polymer layer, the outer polymer layer being impregnated with a biologically active chemical substance that inhibits biofouling-induced chemical, biological, and bio-proliferative damage and that repels biofouling organisms to prevent invasion of the inner polymer layer.

A coating material composition comprising a fluorinated copolymer (A) and a pigment (B), characterized in that the fluorinated copolymer (A) has units represented by the following formula (1) [X and Y are each independently H, F, CF.sub.3 or Cl] and units represented by the following formula (2), the number average molecular weight of the fluorinated copolymer (A) is from 10,000 to 100,000, and the content of the pigment (B) is from 20 to 200 parts by mass, per 100 parts by mass of the fluorinated copolymer (A): ##STR00001##

Methods of protecting a submerged surface include applying an adhesion-promoting layer onto a surface. An inner polymer layer is applied onto the adhesion-promoting layer. The inner polymer layer is impregnated with a biologically active chemical substance that inhibits biofouling-induced chemical, biological, and bio-proliferative damage. An outer polymer layer is applied onto the inner polymer layer. The outer polymer layer is impregnated with a biologically active chemical substance that inhibits biofouling-induced chemical, biological, and bio-proliferative damage and that repels biofouling organisms to prevent invasion of the inner polymer layer.

A fluorochemical composition that includes one or more fluorochemical urethane compounds, a method of treating a substrate (e.g., a method for imparting water and oil repellency and antisoiling characteristics to a substrate), and an article having a fluorochemical composition coating thereon

The invention provides a highly durable surface coating intended to inhibit the formation of ice at sub-0 C. temperatures as well as reduce the accumulation of dirt and insect debris to a vehicle surface upon impact. A continuous, durable matrix surrounds both low-surface-energy (low-adhesion) material inclusions as well as hygroscopic material inclusions. Some variations provide a low-friction, low-adhesion material comprising: a durable continuous matrix; a plurality of first inclusions, dispersed within the matrix, each comprising a low-surface-energy polymer; and a plurality of second inclusions, dispersed within the matrix, each comprising a hygroscopic material. The matrix and the first and second inclusions form a lubricating surface layer in the presence of humidity. Other variations employ a durable continuous matrix and a plurality of inclusions, dispersed within the matrix, each comprising a low-surface-energy polymer surrounding a hygroscopic material. Coating precursors and methods of forming final coatings are also described.
