How the Technology Works
  • Inhibispheres® are porous silica particles containing encapsulated corrosion inhibitors. Their payload is released by diffusion through the porous silica matrix.
  • The spheres can be easily introduced in coating formulations. First you need to mill them into the paint using a bead mill or basket mill. Once you achieved a Hegman grind of 7, you can spray paint them onto a clean substrate.
  • When the coating is damaged, water penetrates inside the coating, triggering the release of the inhibitor from the spheres.
  • The inhibitor diffuses rapidly to the metal surface and stop corrosion.



Inhibispheres® are submicron ceramic particles which can provide specific functionalities to classic coating formulations. Active materials, such as corrosion inhibitors, can be incorporated inside the ‘Smart Particles’, which can then simply be mixed into a paint or coating formulation. The particles are mechanically resistant, can survive paint formulation processes (e.g. mixing, grinding, extrusion) and will not adversely affect the mechanical properties of the coating.
