MSE PRO 50g Graphene Powder for Anti-Corrosion Coating

Anti-corrosion coating type graphene powder Product SKU#: PO0715 Package Size: 50g per bottle (for bulk orders, please contact us for a quote) This anti-corrosion type graphene is prepared by thermal exfoliation reduction. It has high specific surface area and ultra-thin planar structure which benefits the formation of dense physical isolation layer. Its relatively high electrical conductivity helps the activation of zinc powder coating resulting a synergistic effect. It can improve the adhesion and wear resistance of coating, reduce the dosage of zinc powder in the paint. Specifications: Appearance Black powder Package size 50g per bottle Graphene layers multi-layer graphene pH 6.0~8.0 Tap density <0.1 g/cm2 Specific surface area (SSA) 260~350 m2/g Water content <1.0 wt% Particle size D50 <10.0 um C content ≥93 wt% O content <3.0 wt% S content <0.2 wt% Suggestion Dry the graphene powder at 120℃ before use to ensure the best performance Applications: Suitable for all types of (heavy duty) anti-corrosive coatings, such as epoxy zinc-rich primer, (chromium-free) dacromet coating. 2400 h of exposure to salt spray. The samples were coated with a water based two-component epoxy Zinc primer (48% Zinc, 1% graphene by dry-film weight), and demonstrated excellent corrosion resistance. The intended scratch area without coating shows severe corrosion. References: 1. A cautionary note on graphene anti-corrosion coatings, Nature Nanotech 12, 834–835 (2017) 2.
