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.
Inhibispheres® - key advantages compared to traditional anti-corrosion pigments:
Green cost-effective solution: The Inhibispheres® use significantly less active (10-30 times less) for similar performancesdue to their sustained released capability. In contrast to more traditional anti-corrosion pigments, the incorporation of Inhibispheres® inside a paint will not attract additional safety labels on the final product, and you can also produce environmentally friendly coatings based on purely organic inhibitors (metal free), and thus future-proof your formulation.
Simplification of the paint system: The addition of Inhibispheres® does not interfere with optical properties. This means that they can be added to the top coat, providing anti-corrosive properties while maintaining the gloss. This would potentially allow thereplacement of a primer and topcoat system by a single coating (direct-to-metal). This represents a significant cost saving for the end user and the potential to design a premium product for the paint manufacturer.
Additive: The addition of Inhibispheres® to existing anti-corrosion paint formulations can extend the duration of the corrosion protection without significant reformulation.
Compatibilisation: Encapsulation inside the Inhibispheres® enables the use of inhibitors which will normally react with, or result in the destabilisationof the paint chemistry.
Ease of process: The Inhibispheres® can be easily incorporated in a wide range of paints including waterborne, solvent basedand powder coating formulations. The Inhibispheres® are extremely resistant mechanically and can be grinded (pearl mill) or even extruded (powder coating). Finally, the Inhibispheres® do not affect the mechanical or chemical resistance properties of the coating.
