TRIVALENT PASSIVATION ON ZINC
Trivalent chromium base chromate passivation process for zinc and zinc alloy deposits is specially for environment friendly alternative to existing hexavalent chromium based passivations, which are known carcinogenic and major health and environment hazard. In response to new EU guidelines use of Cr+6 based Passivates are to be replaced with Cr+3 based ones. Passivates give improved Corrosion resistance and are now well established alternative in auto and other industries. CMP has long proven products range in this category. Brief information is given below:
TRIPASS IR 100 Silvery yellowish white finish with slight iridescent finish.
TRIPASS BLUE 100 Distinct blue colour with very attractive pleasing finish.
TRIPASS SUPER BLUE 150 Deep blue finish with higher corrosion resistance.
TRIPASS BLUE 20 Good blue colour with very attractive pleasing finish. Cost effective version for general purpose passivation.
TRIPASS SUPER NP 2212 Yellowish iridescent coloured finish with higher corrosion resistance.
TRIPASS BK Deep black finish with very high aesthetic appeal, having good corrosion performance.
BLACK FINISHES
ZINC BLACKENING PROCESS – EBONY BLACK Two stage process producing a rich black colour on zinc deposits and zinc alloy diecastings
BLACK OXIDISING PROCESS FOR STEEL – BOSS A high temperature process for producing a good black finish on steel. Ideal for hand tools and small machine parts. They should be oiled as a final treatment.
BLACK NICKEL PROCESS – NISAL NG Produces a beautiful jet black finish. Ideal for decorative uses on articles as varied as giftware and tools. Can be plated onto brass or nickel plating, subsequently scratch burshed to produce attractive and modern effects. Used on optical equipment, nameplates and photomasks. Used as selective absorber on solar energy collector. Must be lacquered after plating to preserve finish.
