Earlier in 2018 Applied Graphene Materials (AGM) launched their Genable 3000 dispersion range - graphene based, active non-metallic, anti-corrosion additives. AGM has now reported results from further testing, which not only underlines the potential for significant anti-corrosion performance gains but also the products commercial attractiveness particularly under harsher C4/C5 corrosive environments.
Incorporated into the formulation of an industry standard C3 epoxy primer system, and tested under representative cyclical salt spray testing (ASTM G-85-94 Prohesion), Genable 3000 series materials have been shown to deliver a 5-fold extension in coating lifetime, based on a single 60 micron dry film thickness. These results are supported by a detailed mechanical dataset and studies incorporating combination with a PU topcoat exploring intercoat adhesion and overcoating intervals. All results confirm the products attractiveness for development into commercial anti-corrosion systems.
Further investigating Genable 3000 series potential for applications in harsher C4/C5 environments, AGM has embarked on another extensive test program looking at the performance of a higher build primer system. The thickness of this high build primer is around 110 microns, and is therefore typically thinner than many comparative industry standard systems in the C4/C5 category (ISO12944).
AGM says that the properties of the Genable 3000 series make it an ideal tool-box additive for formulators seeking to significantly enhance coating performance in a range of environments. As an additive capable of offering metal free systems with extended durability it is anticipated that the Genable 3000 should find multiple applications in industrial areas subject to high humidity and aggressive atmosphere, including inshore areas of medium to high salinity.
Genable 3000 series dispersions are available initially in epoxy resins but with a range of solvent and water based dispersions under near-term development. All AGM’s Genable dispersions are formulated for long term stability and engineered to aid easy incorporation into existing manufacturing processes.
