    摘要: Aqueous dispersion of a vinylidene fluoride (VdF) polymer which comprises a VdF polymer having a particle size of not more than 200 nm and contains 30 to 50% by weight of solids and not more than 1% by weight of a fluorine-containing surfactant on the basis of water. This aqueous dispersion is prepared by emulsion-polymerizing VdF monomer or a monomer mixture containing VdF under coexistence of not more than 1% by weight of the fluorine-containing surfactant and 0.001 to 0.1% by weight of a nonionic non-fluorine-containing surfactant on the basis of water, and is suitably used for paints.

    摘要: A powder coating composition which comprises (A) a fluorine-containing copolymer having a crosslinkable reactive group and (B) a curing agent being capable of forming crosslinkage by reacting with the crosslinkable reactive group of the fluorine-containing copolymer in a weight ratio (A)/(B) of 40/60 to 98/2, and contains rutile titanium oxide and other pigment. The powder coating composition can form a coating film which can exhibit excellent weather resistance even under very strict environment specified in AAMA 2605 standard, etc., and is suitable particularly for an exterior member for building, for example, an aluminum sash.
