Nanostructured Zinc Nickel
Coating System for Oil and Gas Industries

Designed to replace cadmium, PTFE & ceramic-metallic coatings

June 21, 2022, Houston, Texas ZNnGard™ \`zen·gärd\ is considered part of an overall strategy to replace cadmium, PTFE, ceramic metallic, and fluoropolymer processes, eliminate environmental and worker safety issues while significantly improving performance and reducing life-cycle costs.

Integran Technologies, Inc., Dipsol of America, Inc, and Sigma Fasteners, Inc. are excited to announce their agreements to expand access to Nanostructured Zinc-Nickel fastener and bolting products for the oil and gas industries worldwide.

Steve Cabral, Sigma Fasteners, VP of Business Development
“We are excited to bring this technology to our customers, solving long-standing issues and meeting demands.”

ZNnGard™ replaces toxic plating in addition to other organic coatings that easily chip and flake under torque and require oversized nuts with a sustainable alloy coating that gives a superior performance during installation and long-term corrosion protection. Integran originally developed the pulse-electrodeposition process in 2011 with support from the Department of Defense Strategic Environmental Research and Development Program (SERDP) as an environmentally friendly cadmium-replacement coating for high-strength steel.   

Sigma Fasteners, Dipsol, and Integran have worked together to bring the Nanostructured Zinc Nickel coating system to the Oil and Gas Industries. ZNnGard™ meets the requirements of the ASTM B841 Class 2 as an electrodeposited zinc-nickel alloy coating on fasteners. Integran Technologies is the master licensor for its Nanovate™ Zn-Ni Technology and intellectual property owner in waveform pulse plating technologies. Dipsol America is the master distributor for the expressly branded ZNnGard™ and ZNnCoat™ chemistry and components for plating and chromate finish. Sigma Fasteners, a leader in Energy bolting, will utilize this expertise in converting our current Zn-Ni line to meet Integran standards and Dipsol chemistries to ramp up advanced field testing and production in Houston.

Using technology pioneered in the automotive, electronics, and aerospace industries, the ZNnGard™ system provides the following:

ZNnGard™ – Corrosion control for Energy Transition Bolting requirements and a sustainable future – Corrosion Protection You Can Count On.
