Provided is an aqueous dispersion capable of providing a coating film excellent in solvent resistance, stain resistance, and adhesion to a base material. The invention relates to an aqueous dispersion including a particulate polymer composite; a polyisocyanate compound; and water. The particulate polymer composite includes a fluoropolymer (A) and an acrylic polymer (B). Either or both of the fluoropolymer (A) and the acrylic polymer (B) contain a hydroxyl group and a hydrolyzable silyl group.

Aqueous dispersion, coating film, and coated article

The present invention provides a low-staining room temperature curable coating composition having an excellent low-staining property and recoatability, and comprising (A) a hydroxyl-containing resin, (B) an isocyanate based curing agent, (C) an organosilicate based hydrophilizing agent, (D) a recoatability modifier and (E) an organic solvent, in which the recoatability modifier (D) comprises at least (D1) an amide-containing polymer and (D2) a silane coupling agent.

A vinylidene fluoride copolymer comprising 50 to 90% by mole of units having the formula (I):

Vinylidene fluoride copolymer and composition containing the same

A fluorine-containing copolymer comprising 20 to 60% by mole of the fluoroolefin unit (1), 5 to 45% by mole of the .beta.-methyl substituted .alpha.-olefin unit (2), 1 to 45% by mole of the unit (3) derived from a monomer having a chemically curable functional group, 1 to 45% by mole of the unit (4) derived from a monomer having ester moieties in the side chains and 0 to 45% by mole of the unit (5) derived from a copolymerizable monomer other than the above monomers, if necessary, 0.1 to 15% by mole of the unit (6) derived from a monomer having carboxyl groups. The copolymer can provide a curable composition alone or with an acrylic polymer. The fluorine-containing copolymer is excellent in solvent-solubility, compatibility with curing agents, additives and other polymers, pigment dispersibility, curing reactivity, dispersibility to water, pot life, film forming ability, coating properties, and the like. The coating film prepared from the copolymer has a high weatherability and is excellent in film properties such as stain resistance, heat-yellowing resistance, dechlorination resistance, optical properties, adhesion to a substrate, mechanical properties, heat resistance, chemical resistance, solvent (gasoline) resistance, water resistance and good appearance of finished products.

Fluorine-containing copolymer and curable composition containing the same

A vinylidene fluoride resin composition which comprises (A) 10 to 95 parts by weight of a vinylidene fluoride resin, (B) 1 to 80 parts by weight of a resin having a poor compatibility with said vinylidene fluoride resin (A), and (C) 1 to 30 parts by weight of a resin having an excellent compatibility with both said vinylidene fluoride resin (A) and said resin (B), total amount of said resins (A), (B) and (C) being 100 parts by weight. The film obtained by baking the composition of the present invention has the structure that the surface side is rich in the VdF resin, and the excellent adhesion to the substrate. Consequently, the film has the excellent chemical resistance, adhesion to a substrate, and the like.

Vinylidene fluoride resin composition

A water- and oil-repellent of a copolymer which comprises repeating units derived from (a) a monomeric compound having at least a perfluoroalkyl or perfluoroalkenyl group and an acrylate or methacrylate group and (b) a methacrylate, a homopolymer of which has a glass transition temperature of not lower than 115.degree. C., which has good resistance to dry cleaning and resistance to slippage.
