Title:
FINISHING AGENT FOR TRIVALENT CHROMIUM CHEMICAL CONVERSION COATING FILM, AND METHOD FOR FINISHING BLACK TRIVALENT CHROMIUM CHEMICAL CONVERSION COATING FILM
Document Type and Number:
WIPO Patent Application WO/2012/137680
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a water-soluble finishing agent for a trivalent chromium chemical conversion coating film, which has low insulation, no problems with tightening properties, outstanding gloss and high corrosion resistance, and can obtain a trivalent chromium chemical conversion coating film, especially a black trivalent chromium chemical conversion coating film, having few scratches and flaws. The finishing agent for a trivalent chromium chemical conversion coating film is characterized by containing a trivalent chromium source, a phosphate ion source, a zinc ion source, a chelating agent which can form a complex with trivalent chromium, and a non-ionic water-soluble polymer compound selected from a group comprising poly(vinyl alcohol) and derivatives thereof, poly(vinyl pyrrolidone) and derivatives thereof, poly(alkylene glycol)s and derivatives thereof, and cellulose ethers and derivatives thereof.
