ZENTEK PROVIDES UPDATE ON ZENARMOR(TM) CORROSION PROTECTION TECHNOLOGY

Zentek Ltd. has been awarded a research and development contract through Innovative Solutions Canada (ISC) to test ZenArmor nanopigment in military-grade, chromate-free, corrosion protection aerospace paint systems. The company previously announced in its Feb. 8, 2023, news release that it had been conditionally qualified for the ISC-TS (ISC-Testing Stream) pending a government of Canada organization confirming an interest in the ZenArmor technology.

The testing will be conducted under the supervision of Dr. Qi Yang and Dr. Naiheng Song, research officers at the National Research Council of Canada (NRC) Aerospace Research Centre's Aerospace Manufacturing Technologies Centre (AMTC).

Test objectives include:

• Confirm ZenArmor meets the required aviation standards;
• Optimize the concentration of ZenArmor in aviation paint systems;
• Compare the corrosion protection of ZenArmor to chromate-based paint system.

"We are grateful to have been selected for this ISC-TS by our partners at the National Research Council of Canada, which we believe is an important step in continuing to prove out the efficacy of our ZenArmor technology in corrosion protection paints. This is an area that has taken on heightened importance due to the high cost of corrosion. This award confirms the government of Canada's commitment to working with innovative domestic companies to help address this challenge," commented Greg Fenton, Zentek chief executive officer. "Importantly, we see this as a potential precursor to commercialize our technology not only within the Canadian government, but with other interested parties as well."
