Integran Technologies, Inc., Dipsol of America, Inc, and Sigma Fasteners, Inc. have announced agreements to expand access to nanostructured zinc-nickel fastener and bolting products for the oil and gas industries worldwide.
The three companies have worked together to bring the ZNnGard 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 its 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 is said to provide the following:
- Refined grain size – Improved hardness, corrosion resistance, friction coefficient, and appearance.
- Low porosity – An alloy coating with a uniform coating composition, leading to excellent corrosion resistance.
- No hydrogen embrittlement – Consistently passes ASTM F519 hydrogen embrittlement testing and re-embrittlement (a.k.a., in-service embrittlement) testing.
- ASTM B117 – Salt spray resistance exceeding 3000-5000 hours depending on thickness requirements.
Sigma Fasteners, Dipsol, and Integran have stated ZNnGard is considered part of an overall strategy to replace cadmium, PTFE, ceramic metallic, and fluoropolymer processes, eliminate environmental and worker safety issues while improving performance and reducing life-cycle costs.
