None chromate and None Chrome Conversion Coating
Sanchem on Zinc, Aluminum and Magnesium
Paramount Metal Finishing applies Sanchem conversion coatings on zinc, magnesium and aluminum. Sanchem is a RoHS compliant chromate-free conversion coating that leaves an electrically conductive clear to gold protective surface treatment. Sanchem is an excellent preparation of aluminum, magnesium or zinc substrates for paint, powder coating and e-coat as well as adhesives. Sanchem can produce far better coating adhesion comparable to hexavalent chromate conversion coatings.
Sanchem is a high-performance conversion coating that offers:
Paramount Metal Finishing applies Sanchem conversion coatings to Zinc, Aluminum, and Magnesium cast or wrought substrates. Paramount Metal Finishing can coat Sanchem treated substrates with various paints, powder coatings and dry-film lubricants.

The annual global cost of corrosion is $2.5 trillion, equivalent to 3.4% of the worldwide GDP. In the US, the annual cost of corrosion surged past $1 trillion, affecting our national GDP by 6.2%. Corrosion affects infrastructure, transportation, production & manufacturing, utilities, and the federal government.
Chemical based methods to control the detriments of corrosion include:
Per the values given, the traditional methods to control corrosion fall short, In fact, far short.
In a major development to minimize corrosion, thereby improving field service life of parts in challenging conditions, Zinc – Nickel alloy (ZN-Ni) plated finishes provide significant benefits. These include not only corrosion protection, but improved hardness, service life, and wear resistance.
Straight zinc plated deposits provide sacrificial corrosion protection over steel substrates. It is accomplished by the zinc deposit’s anodic potential to corrode first, protecting the steel base. This has been an industry accepted application for decades.
Paramount Metal Finishing offers a unique, significant improvement to corrosion protection. It is the Zinc – Nickel alloy deposit (Zn-Ni), composed of 85% Zinc & 15% Nickel. The focus of corrosion protection is immediately obvious by results of the ASTM B-117 Salt Spray Testing, on equivalent deposit thicknesses.
Salt Spray Results for Electroplated Deposits
|Deposit||Hours to White Corrosion||Hours to red Corrosion|
|Zinc – Nickel (Zn-Ni)||350-400||1,000-1,200|
The corrosion protection afforded by a deposit of Zn-Ni significantly outperforms straight Zinc by 2.7:1 (white corrosion) and significantly by 4.9:1 to red corrosion.
The Zn-Ni alloy deposit consists of 85% Zinc and 15% Nickel. Deposits normally range in thickness of 8-14 um, followed by a trivalent chromate of 0.06-0.1 um thickness.
Zn-Ni deposits approach 450 Vickers hardness. By comparison, Zinc deposits fall below 150 Vickers.
Zn-Ni deposits resist thermal stresses approaching 200 degC (392 degF) compared to Zinc deposits at only 120 degC (248 degF.
Other outstanding features of the Zn-Ni deposit include:
Paramount Metal Finishing applies Zn-Ni to a variety of commercial and military parts, including: automotive, power generation, fasteners, construction, agricultural equipment, firearms, aerospace, lawn & garden, transportation, and heavy equipment.
Finishing capabilities range from standard parts to larger sizes and dimensions,

Paramount Metal Finishing continues to stay on the leading edge of finishing by introducing a new form of coating for military customers, a Chemical Agent Resistant Coating (CARC) powder coat. With the government’s approval of spec MIL-PRF 32348 Type III, Paramount is proud to become one of the few finishers to offer CARC powder coat as an option for their customers.
CARCs are optimal for military applications because of the unique set of properties they contain. Key properties of CARCs include the ability to withstand harsh chemicals of decontamination, ability to withstand extreme weather, keep a low gloss unit, and also emit the proper infrared signal.
The push for the development of a CARC powder is the result from an extensive list of advantages that powder coating has over its wet spray predecessor. With advantages in categories like cost, application, consistency, worker safety, and environmental safety, powder coating makes a great alternative when the situation allows for it.
Paramount Metal Finishing currently offers CARC powder coating in two colors; Desert Tan (FED STD #33446) and Black (FED STD #37070). We also look forward to adding Green (FED STD #34088) when made available from suppliers.
Lead by a desire for new applications and technology in finishing, PMF remains committed to stay on the leading edge of finishing.
