Passivates Post Treatment

Passivates post-treatment is a finishing process to prevent corrosion on zinc after chromating. The finishing process uses a simple immersion method and provide a protective thin layer onto the chromating layer.

KM 26 SEALER Water-Based sealant for blue and yellow passivates on zinc and zinc alloy coatings

Physical Properties: 
KM 26 SEALER: Odourless Liquid

Description

KM 26 Sealer is a water-based sealant specially formulated for the use with Trivalent Blue and Yellow Passivation on zinc and zinc alloy coatings.

KM 26 Sealer is applied by using a simple immersion after the passivation and will form a thin film on the surface, with good resistance to corrosion.

Best corrosion results are obtained using with Kemia’s Zn 1508 / ZN 1506 and Zn 1575 passivates. The product is non-toxic and can be installed as the final stages on any plating line.

KM 26 Sealer films also have good tolerance to thermal shock baking at 120 degree C for one hour and without significant loss of corrosion resistance.

Equipment

Tank: Steel tanks lined with PVC
Heater: Quartz or stainless steel

KM 36 TOP SEAL SILICATE FREE, WATER BASED TRIVALENT CHROMATE TOP SEAL

Physical Properties: 
KM 36 TOP SEAL: Liquid

Description

KM 36 Top Seal is a silicate-free, water-based Trivalent Chromate Top Seal specially formulated for the use with Trivalent Black Passivation to improve brightness and increase corrosion protection.

KM 36 Top Seal is used as a final rinse. KM 36 Top Seal has low viscosity and produces very thin, uniform coatings making it suitable for both rack and barrel operations.

Equipment

Tank: PP, PVC
Heater: Quartz or Telfon

ZN BLUE DYE 150: Powder

Description

ZN BLUE DYE 150 produces a uniform metric appearance on zinc plated parts when used with chromating solution.

ZN BLUE DYE 150 can be applied on chromated zinc plated parts from alkaline cyanide-free, acid chloride, and cyanide zinc plating baths.

Equipment

Tank: PP or PVC
Heater: Stainless steel

ZN TRI-V YELLOW CONVERTER Yellow Liquid Dye for Trivalent Chromated Zinc Plated Parts TECHNICAL DATA

Description

ZN TRI-V YELLOW CONVERTER is added directly to the ZN TRI-V 120 chromate solution to form an “all” trivalent conversion coating.

ZN TRI-V YELLOW CONVERTER reacts within the ZN TRI-V 120 chromate to produce a uniform, stable conversion coating over the entire surface of the part.

ZN TRI-V YELLOW CONVERTER works equally well on chromated zinc-plated parts from alkaline cyanide-free, acid chloride and cyanide zinc plating baths.

ZN TRI-V YELLOW CONVERTER will exceed 120 hours of neutral salt spray to corrosion products.

ZN TRI-V YELLOW CONVERTER is compatible with Kemia top coats.

ZN TRI-V YELLOW CONVERTER can be used in ZN Tri-V.
