FreeBlack 3540 produces a uniform, gloss black all trivalent conversion coating on electroplated zinc

FreeBlack 3540 uses ZINCOGUARD BLACK , a revolutionary, thin-uniform film topcoat. Parts processed in ZINCOGUARD BLACK actually bead-up and repel humidity and salt spray mist to form a water repellent barrier that provides superior corrosion protection.

FreeBlack 3540 has excellent stability and shelf life.

FreeBlack 3540 when top coated with ZINCOGUARD BLACK will provide 96-120 hours to white corrosion for barrel parts and 120-144 hours to white corrosion for rack plated parts.

FreeBlack 3540 is a ‘slow growth’chromate film builder which maximizes salt spray hours and provides optimum color and gloss.
