R·G-165 Trivalent Iridescent Passivation
Performance & Features
Identical technical characteristics as DS-160:
Made of fully imported German raw materials, hexavalent-chromium-free eco trivalent chromium passivation for manual & automatic lines, perfect for EU & US export goods.
- Clear light rainbow film; optional 180B additive delivers dark iridescent tone close to hexavalent chromate; dye-free formula.
- NSS resistance >120h under ASTM B-117 standard, widely used for automotive components.
- Compact film layer, no color fading after passivation; thermal baking does not weaken corrosion resistance.
- Easy maintenance, long bath life and economical cost.
