| description | FIELD: metal surface chemical treatment. ^ SUBSTANCE: invention relates to compositions for chemical treatment of metal surfaces preventing corrosion of metal and designed to prepare metal surface for deposition of lacquer coating without preliminary removal of corrosion products. Water-based composition contains 45-60% orthophosphoric acid, 2.0-3.5% zinc nitrate, 2.5-4.0% potassium ferrocyanide, and 0.1-0.3% nonionic fluorocarbon surfactant of general formula RFCONH(C2H4O)nH, wherein RF represents C6F13-, C8F17-, or C2F5OC3F6OC2F4-, and n = 10-15. ^ EFFECT: prolonged service time of metal articles, prevented further corrosion of metal, and increased storage time of composition. ^ 3 ex |
