Abstract: The present invention relates to a corrosion-protective composition containing a wax, an unsubstituted or substituted polyaniline in a doped form and a liquid paraffin, and articles comprising the composition applied on a substrate. It also relates to a process for manufacturing the composition, wherein i) a first dispersion of a polyaniline in a doped form is prepared; and ii) the first dispersion of the polyaniline is combined with a wax component to sufficiently disperse the polyaniline therein, and to the use of the composition as a single layer coating for the protection against corrosion of a substrate in need thereof.

Abstract: A pretreatment apparatus for performing pretreatment before a painting process includes a treatment tank to be filled with a treatment liquid for degreasing and chemical conversion. A circuit section forms a circulation path for circulating the treatment liquid from the treatment tank to the treatment tank. A purifying section removes dust, chemical sludge and oil from the treatment liquid circulated to the treatment tank through the circulation path.

Abstract: Equipment of pretreatment before painting for a composite vehicle body comprises a treatment tank, an aluminum chemical conversion unit, and a rinse unit. The treatment tank is filled with a degreasing and chemical conversion solution containing a mixed solution of a polar organic solvent and water, any of sodium ion and lithium ion, phosphate ion, zinc ion, nickel ion, manganese ion, and any of nitrate ion and nitrite ion. The mixed solution has a weight ratio of the polar organic solution to the water in a range of 2.8:7.2 to 3.8:6.2. The aluminum chemical conversion unit treats the composite vehicle body with a chemical conversion solution for aluminum. The rinse unit washes the composite vehicle body with a washing solution.
