Product Info-
COLLOY A-Z-N 300
Latest generation acid zinc-nickel plating process that offers enhanced ductility and throwing power. Provides a level, mirror bright, ductile electro-deposited zinc-nickel alloy containing from 12% to 15% nickel that is evenly distributed at low, mid and high current densities. Process operates at lower, more economical temperatures, is free from boric acid and ammonium salts and ideal for use on castings or heat treated steel components.
-
COLLOY NI-Z-POSIT II
Next generation alkaline cyanide free zinc-nickel plating process. Provides a bright, ductile zinc-nickel deposit containing 12% – 15% Ni. Readily accepts clear, blue, black and high corrosion trivalent passivations.

-
COLLOY NI-Z-POSIT III
The latest process for zinc/nickel alloy plating from an alkaline cyanide-free bath.
-
COLTIN-ZN
COLTIN-Zn provides an excellent finish for all grounding applications. It has excellent lubricity (torque-tension), delivers outstanding salt spray results, and mitigates galvanic corrosion rate in contact with aluminum and magnesium. COLTIN-Zn is a uniform, level, and ductile tin-zinc alloy with excellent adhesion properties.
-
COLDIP® TZ 10
COLDIP® TZ-10 is specifically designed and formulated for tin-zinc alloy. It operates over a wide range of alloy content, formulated to tolerate temperatures used in baking for hydrogen relief, and formulated to precipitate zinc and iron from the bath, preventing a decrease in performance. COLDIP® TZ-10 is an easy-to-use one-part system that provides over 1,000 hours to white corrosion and up to 1,500 hours to red corrosion when properly applied.
-
COLDIP® NI-Z CLEAR 100TP CFT
COLDIP® NI-Z CLEAR 100TP CFT is a trivalent passivation for zinc-nickel alloy that yields a silver (clear) color with Cobalt Free Technology (CFT). It is operated under mild conditions that result in very low thickness loss during passivation and is a cost-effective alternative to high corrosion finishes.
-
COLDIP® NI-Z BLACK 505 CFT
COLDIP® NI-Z BLACK 505 CFT is a unique trivalent chromium, cobalt-free black conversion coating for electroplated zinc-nickel alloy. It is a two-component system for simple operation that produces a uniform, gloss-black, scratch-resistant finish which achieves over 400 hours to white corrosion and over 1,000 hours to red rust when sealed with a Columbia Chemical sealer. COLDIP® NI-Z BLACK 505 CFT works over a very wide nickel alloy content range of 11 – 17% and has been developed to reduce thickness loss during passivation and to reduce increases in nickel weight percent following passivation. COLDIP® NI-Z BLACK 505 CFT is ideal for both rack and barrel installations using alkaline and acid zinc-nickel deposits.

COLDIP® NI-Z BLACK 510
COLDIP NI-Z BLACK 510 is a unique trivalent chromium black conversion coating for electroplated zinc-nickel alloy that produces a uniform, gloss-black, scratch-resistant finish. COLDIP® NI-Z BLACK 510 achieves over 240 hours to white corrosion and over 1,000 hours to red rust when sealed with a Columbia Chemical sealer. It works over a very wide nickel alloy content range of 11 – 17% and was developed to reduce thickness loss during passivation and to reduce increases in nickel weight percent following passivation. COLDIP® NI-Z BLACK 510 is ideal for both rack and barrel installations using alkaline and acid zinc-nickel deposits.

COLDIP® NI-Z SAPPHIRE 400
High-corrosion resistant bright blue trivalent passivate for use in the rapidly growing Zinc Nickel (ZnNi) electroplating Industry. Imparts an aesthetically pleasing blue-bright conversion coating which, when applied properly, will produce a finish that exceeds 400 hours of neutral salt spray to white corrosion products.
-
COLDIP® NI-Z TRI BLUE 100
COLDIP® NI-Z TRI BLUE 100 is a unique trivalent passivating conversion coating for electroplated zinc-nickel alloys. COLDIP® NI-Z TRI BLUE 100 will impart an aesthetically pleasing clear, colorless conversion coating which when applied properly will produce a finish that exceeds 250 hours of neutral salt spray to white corrosion products. COLDIP® NI-Z TRI BLUE 100 is operated under mild conditions that results in very low thickness loss during passivation and is a cost-effective alternative to high corrosion finishes. COLDIP® NI-Z TRI BLUE 100 when top coated with Zinc-Chro-SHIELD® will provide 500 hours to white corrosion products.
-
COLDIP® Ni-Z Clear 250
Unique Trivalent passivating conversion coating for electroplated zinc-nickel alloys. Imparts an aesthetically pleasing clear, colorless conversion coating which when applied properly will produce a finish that exceeds 250 hours of neutral salt spray to white corrosion products.
-
COLDIP® NI-Z Black Diamond 500
Unique trivalent black conversion coating for electroplated zinc-nickel alloy. Ideal for both rack and barrel installations using alkaline and acid-nickel deposits. Produces a uniform, gloss-black, scratch-resistant finish and works over a very wide nickel alloy content range of 11% – 17%. Achieves over 400 hours to white corrosion and over 1,000 hours to red rust when sealed with Columbia Chemical sealer.
