摘要： PURPOSE:To obtain a matte coating film excellent in coating appearance and film performances by using a polymer obtained by radical-polymerizing a vinyl monomer having a specified group in the presence of a fluoropolymer as a vehicle component. CONSTITUTION:An anionic matte electrodeposition coating composition is obtained by using as a vehicle component a polymer obtained by radical- polymerizing an alkoxysilane-containing vinyl monomer (e.g. divinyldimethoxysilane) in the presence of a fluoropolymer (e.g. a hydroxylated fluoropolymer comprising hydroxyethyl vinyl ether and tetrafluoroethylene). Because said polymer contains an alkoxysilane group in the side chain, it forms a silanol by hydrolysis when dispersed in water and further forms a siloxane bond by the condensation of the silanol groups to form a fine roughened surface. Even when it is cured by baking, the coating film gives a roughened surface without causing perfect meltflow. In this way, a matte coating film can be obtained.

摘要： PURPOSE:To form a coating film having excellent resistance to heat and corrosion, etc., by applying an inorg. paint contg. an organosilicon high condensate contg. no silanol group at its terminals as a film-forming component to an anodized Al (alloy) and drying it. CONSTITUTION:An organosilicon compd. of formula I (wherein R is a 1-8C hydrocarbon group) such as tetramethoxysilane (or low condensate of the compd. of formula I ) is mixed with an organosilicon compd. of formula II (wherein R is a 1-12C hydrocarbon group) such as methyltrimethoxysilane (or low condensate of the compd. of formula II). The mixture is hydrolyzed in the presence of an acid catalyst such as hydrochloric acid, the pH is adjusted to 7 or above by adding an alkaline substance and the hydrolyzate is condensed. The resulting organosilicon high condensate contg. no silanol group at its terminals is used as a film-forming component to prepare an inorg. paint. The paint is applied to an anodized or bonderized Al (alloy) and dried at room temp. or by heating.

摘要： PURPOSE:To adjust the gloss of the electrodeposition coating film with one kind of paint by conducting the current application of electrodeposition coating in two stages including a stopping stage in the delustering electrodeposition coating method in which a material to be coated is baked and cured using an anionic electrodeposition paint consisting of a specified resin. CONSTITUTION:A material is coated in the anionic electrodeposition paint bath consisting of an acrylic copolymer having an alkoxy-silane group in the side chain and an amino resin and then baked and cured to obtain a delustered coating film. In this electro-deposition coating method, the current application of coating is conducted in two primary and secondary stages, and a current stopping stage is provided between the two stages. The time, voltage and current density in each stage are appropriately set to adjust the gloss of the coating film. Although the current applying and stopping times are controlled to >=6sec without any special limit, the primary current applying time is appropriately controlled to 10-180sec and the secondary current applying time to 10-280sec.

摘要： PURPOSE:To form an anion electrodepositing film excellent in durability at low cost by electrodepositing the surface of an Al-based metallic member with acrylic resin electrodeposition coating and thereafter successively electrodepositing the surface with fluororesin electrodeposition coating having specified electrodeposition film polarization value. CONSTITUTION:The surface of a member made of Al or Al alloy is electrodeposited with anion type acrylic resin electrodeposition coating described hereunder at 0.01-0.7mA/cm minimum electrodeposition current density.

Then an anion electrodepositing film excellent in durability is formed at low cost by electrodepositing anion type fluororesin electrodeposition film wherein the heretofore known electrodeposition film polarization value (kOMEGA.cm ) is the same polarization value as the above-mentioned anion type acrylic resin electrodeposition coating or its difference is small value of about 1500 in the maximum at 0.01-0.7mA/cm minimum electrodeposition current density or at 0.6mA/cm smaller than it in the maximum.
