Treating tin-plated steel sheet with a composition containing titanium or zirconium compounds

Treating tin-plated steel sheet with a composition containing titanium or zirconium compounds. Oda, Nobuyuki; Terada, Haruyoshi (Oxy Metal Industries Corp., USA). Can. CA 1162504 A1 21 Feb 1984, 15 pp. (English). (Canada). CODEN: CAXXA4. CLASS: IC: C25D009-02; C25D013-08. APPLICATION: CA 80-365474 25 Nov 1980. DOCUMENT TYPE: Patent CA Section: 55 (Ferrous Metals and Alloys) Tin plate for cans is coated for corrosion resistance and paintability with a soln. contg. a sol. Ti or Zr compd., a pyrazole deriv., a myoinositol phosphate ester, and a Si compd. The tin plate is degreased and immersed or sprayed for 5-10 s at 10-90° in the soln. adjusted to pH 1-10 and dried without or with a water rinse. Alternatively, the tin plate may be immersed in the soln. and electrolyzed, with the surface as anode, at 0.1-50 A/dm2 for 0.1 s-2 min. Thus, a tin plate was degreased and rinsed, and sprayed with a soln. of 3-methyl-5-hydroxypyrazole [4344-87-0] 10, phytic acid [83-86-3] 5, H2ZrF6 [12021-95-3] 25, g-aminopropyltriethoxysilane [919-30-2] 5, HF 2, and H2O2 2 g in 100 mL H2O at 45°, rinsed with tap water and deionized water, and dried at 200°. The corrosion resistance and paint adhesion were good.

Anticorrosion wrapping for metals

Anticorrosion wrapping for metals. Tanaka, Tadashi; Obi, Tatsuro; Tanikawa, Keiichi (Nippon Steel Corp., Japan). Japan. Kokai JP 51103043 11 Sep 1976 Showa, 4 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: C23F011-02. APPLICATION: JP 75-27536 6 Mar 1975. DOCUMENT TYPE: Patent CA Section: 56 (Nonferrous Metals and Alloys) Section cross-reference(s): 43 The wrapping contains at least one pyrazole (I; R1 H, CH2OH, CONH2, CH2CO2H; R, R2 = C1-10 alkyl, OH, CH2OH; R3 = H, NH2). Thus, kraft paper having a polyethylene film on 1 side was sprayed with 5 g 3-methyl-5-hydroxypyrazole [4344-87-0]/m2. When galvanized steel sheet was wrapped in the paper, no surface changes were obsd. at 49.degree. and 98% humidity after 10 days. With paper treated with benzotriazole, corrosion occurred.
