Armis is a graphene solution for paint and coating systems — adding reduced graphene oxide (rGO) to create a physical nanoscale barrier against oxygen, moisture, and corrosive species. It integrates into water-based and solvent-based systems without reformulation, and is characterised to a defined specification in every batch.
Conventional anti-corrosion coatings rely on active inhibitors — zinc oxide, zinc phosphate — that work by releasing ions to suppress corrosion. It works, but incompletely. As the inhibitor depletes, protection degrades. Barrier properties depend entirely on the binder, and most binders are inherently permeable to oxygen and moisture at the molecular level.
Armis addresses the barrier problem at the nanoscale — without reformulating the binder system.
Armis introduces reduced graphene oxide (rGO) into the coating matrix as a ready-to-use graphene solution — available in aqueous dispersion for water-based systems and solvent (xylene) dispersion for solvent-based systems. No reformulation of the binder is required.
rGO platelets orient parallel to the substrate surface, creating a tortuous path for oxygen, water, and chloride ions. Corrosive species must navigate around multiple overlapping nanosheets to reach the substrate — dramatically increasing effective diffusion distance.
rGO’s exceptional tensile strength and interfacial adhesion properties reduce micro-cracking in the binder under thermal cycling and UV stress — preserving barrier integrity over time.
Oxygen-containing functional groups on the rGO surface (carbon: 86%, oxygen: 14%) create chemical anchoring points within the polymeric matrix — improving dispersion stability and long-term adhesion of the graphene network.
ZnO and zinc phosphate are active corrosion inhibitors — they work by releasing Zn²⁺ ions that react with corrosion products. This depletes over time and introduces zinc into the environment. rGO is a passive barrier — it does not leach, does not deplete, and does not depend on ion release. The protection mechanism is physical, not chemical.

Even contrast. Good uniformity confirmed by FESEM
What the zeta potential tells a formulator:−44 mV in aqueous dispersion indicates excellent long-term colloidal stability — the rGO platelets repel each other strongly enough to resist aggregation during storage and after addition to the coating. This is a critical parameter for ensuring uniform distribution in the paint film.
Adding rGO to coating formulations creates a physical barrier at the nanoscale — blocking oxygen and moisture ingress at the molecular level, measurably extending protection without reformulating your entire system.
