Dedicated to strengthening the corrosion resistance of aluminum passivating agent

Dedicated to strengthening the corrosion resistance of aluminum passivating agent (green aluminum passivating agent, trivalent chromium coating agent, aluminum special formation agent) 1. Process characteristics: product complies with the EU "ROHS", "WEEE" Directive stipulates that meet environmental protection Claim. Trivalent chromium for the production of aluminum, the aluminum include aluminum, aluminum alloy and aluminum die casting; corrosion ability, performance is better than hexavalent chromium passivation process, the neutral salt spray can reach more than 360 hours ; passivation after forming a transparent, light color coating, the specific color is determined by the purity of aluminum; coating temperature is good, it can be 100 ℃ high temperature corrosion resistance without reducing their capacity; high coating agent concentration, consumption low volume; can be used for aluminum painting, powder coating and gluing pre-treatment process; immersion, spray and wipe processes are easy to operate. 2. The aluminum coating agent consumption: consumption in most of out of loss of one square meter per treatment products (including drag-out), add 15-20 ml of concentrate. 3. Common process: degreasing - weak corrosion Alkaline - Acidic ash - passivation - drying aging Miss Liu: 15989966842 QQ: 3057891720 Website: http: //www.fsrchg.com/?
