摘要:
Proposed are metal-pigment dispersions consisting of flake-form metal pigments produced by grinding plus a binder or binder solution, the pigments containing no reaction or decomposition products of fatty acids produced by reaction with the pigment in the presence of atmospheric oxygen, or less than 0.01 % by wt. of such reaction or decomposition products. Also described are a method for the production of such dispersions, the pigment being ground with the binder in a ball mill, and the use of such dispersions in the manufacture of paints, dyes and inks, in particular printing inks.
摘要:
A chromium-free, stable, water dispersion of zinc powder is produced by incorporation, into a zinc powder, of a silane coupling agent having a mercapto group in its molecules. The coupling agent is present in an amount ranging from 0,1 to 10 parts by weight for every 100 parts by weight of the zinc powder. The composition may be used in a water base paint.
摘要:
A composite metallic powder composition usable as an excellent pigment for water-base coating material, wherein the composite metallic powder is produced by chemically bonding an isocyanate compound to the surface of a surface-treated metallic particle and further chemically combining a phosphorus compound with the isocyanate compound via a urethane linkage.
摘要:
The present invention provides a chromate-free coating composition having excellent corrosion resistance. The coating composition includes a binder system comprising a resin and a pigment system including a metal alloy pigment component and optionally, a carbonaceous component. Coated articles with the coating composition applied to at least a portion of a surface thereof are also provided.
摘要:
Metal effect pigment with additive, which: is at least partially applied to the metallic effect pigment; and includes at least one carboxylic acid with at least 4C, as structure units and at least one polyglycolether, where the carboxylic acid and polyglycol are covalently linked together, is claimed. An independent claim is included for the metal effect pigment comprising (a) pulverizing metal particle of metal effect pigment in the presence of additive, and grinding media and optionally a fluid phase; (b) separating the product obtained in step (a); and (c) optionally compacting separated product in step (b).
