摘要： PURPOSE:To reconcile edge corrosion resistance and excellent appearance by setting the lowest melt viscosity of a film at the time of curing calculated from the measurement of the logarithmic attenuation factor in a pendulum type viscoelasticity measuring device to a specific value or more. CONSTITUTION:In order to enhance the edge corrosion resistance of a steel plate, it is necessary that the lowest melt viscosity of electrodeposition paint is 0.2 or more and, when said melt viscosity is below 0.2, edge corrosion resistance is inferior. As a composition of an electrodeposition resin achieving 0.2 or more, there is a composition consisting of a component 1 and a component 2 and the solid ratio 2/1 of the components 1, 2 is 0.03-0.15. When the solid ratio is larger than 0.15, edge corrosion resistance is enhanced but the smoothness of a coating surface is markedly inferior and both properties are not satisfied. The component 1 is a cationic thermosetting resin and the already crosslinked fine resin particles in the cation electrodeposition paint being the component 2 are obtained by the addition polymerization of a compound A containing two or more primary amino groups in one molecule thereof and a compound B containing two or more alpha,beta-ethylenic unsaturated groups in one molecule thereof and contain a cationic group and the mean particle size thereof is 0.01-1mum.

摘要： PURPOSE: To provide an anticorrosive water-based coating composition which, even when applied directly to an iron surface, does not cuase the so-called flash rust, that is, spot rust scattered on the coated surface or iron surface rust. CONSTITUTION: This composition comprises 100 pts.wt. water-based coating material, 0.5-5 pts.wt. rust-preventive pigment and 0.05-1.0 pt.wt. at least one corrosion inhibitor selected from among sodium nitrite, ammonium nitrite, calcium nitrite, sodium sulfite, sodium benzoate and ammonium benzoate.

摘要： PURPOSE:To obtain the title composition improved in low-temperature curability and shelf stability by neutralizing a mixture of a resin containing both a cationic group and an active hydrogen atom with a specified reaction product with an organic acid and dissolving or dispersing the resulting product in water. CONSTITUTION:An epoxy resin (e.g., bisphenol A epoxy resin) is reacted with a cationizing agent (e.g., diethanolamine) to obtain a resin (a) containing both a cationic group and an active hydrogen atom which becomes water-soluble when partially neutralized with an acid. Separately, an isocyanate or a polyisocyanate having allophanate and/or biuret structures is reacted with a blocking agent selected from among an oxime, acetylacetone, malonic diester and an acetoacetate to obtain a reaction product (b). Component (a) is mixed with 0.1-2.0 pts.wt., per pt.wt. solid matter of component (a), component (b) to obtain a mixture. This mixture is neutralized with an organic acid and dissolved or dispersed in water.

摘要： PURPOSE:To improve corrosion resistance and to prevent deterioration in strength by applying prescribed coating material to a high tensile steel in which compressive residual stress-applying working is exerted on the surface to improve fatigue strength and then subjecting the above applied coating to baking hardening. CONSTITUTION:The high tensile steel product is formed by applying coating material to a steel stock of >=40kg/mm tensile strength in which residual stress is established at the surface and then applying baking hardening to the above applied coating at >=130 deg.C. The above paint is formed of a cationic electrodeposition coating composition being hardened at

摘要： PURPOSE:To considerably improve the rust preventiveness of parts of an automobile body, household electrical appliances or the like coated by electrodeposition, by post-treating the coated parts with an aq. soln. contg. specified metal ions before the formed paint films cure. CONSTITUTION:Parts of an automobile body, automotive parts, household electrical appliances or the like requiring rust preventiveness are coated with a cationic or anionic electrodeposition paint. Before the formed paint films cure, the coated parts are immersed in an aq. soln. contg. an inorg. or org. acid salt of one or more among Zn, Ni, Sn, Pb, Cr, Sr, Co, Mn, Mo and Zr at 0.1-20wt.% concn. of metal ions for about 3-300sec. The soln. may be sprayed on the coated parts under 30-200V voltage impressed. The corrosion preventiveness of the coated parts is remarkably improved.

摘要： PURPOSE:To form the coat of a heavy metal and that of a polymer in one bath, by dipping a steel sheet to be treated in an electrodeposition paint contg. a heavy metal ion and an ionized polymer, and impressing specified different voltages between the sheet and the counter electrode. CONSTITUTION:The electrodeposition paint contains >=0.1wt.% heavy metal ion such as the org. acid salt and the inorg. acid salt of the heavy metal such as Pb, Sn, Zn, Cr, Sr, and Ni and the cationic polymer ion obtained by neutralizing the epoxy resin, polybutadiene resin, acrylic resin, etc., contg. the basic group such as an amino group, an ammonium group, a sulfonium group, etc., with the org. and inorg. salts such as formate, acetate, sulftate, hydrochloride, and phosphate. The electrically conductive substrate such as a steel sheet is dipped in the paint, a voltage at 10-30V is firstly impressed between the sheet and the counter electrode to form a heavy metal coat on the steel sheet surface, and a voltage at 40-80V is then impressed to form a polymer coat. The coat of the composite electrodeposition paint having excellent corrosion resistance resulting from the heavy metal and the polymer is thus formed.
