Description
GEO-SGK98 Series is a surface modified graphite developed for high-performance anticorrosive and marine coating applications. The surface treatment improves wetting, dispersion, and coupling with resin systems, while the natural flake graphite structure creates a tortuous path that slows the penetration of corrosive media through the coating film.
This unique barrier mechanism helps improve long-term corrosion resistance in aggressive marine, offshore, industrial, and infrastructure environments. GEO-SGK98 is compatible with epoxy, polyurethane, and vinyl coating systems where durability and protection are critical.
Key Properties
• High-aspect-ratio flake structure extends the diffusion path for corrosive media
• Improves barrier protection against water, oxygen, and chloride ions
• Surface treatment enhances wetting and resin compatibility
• Excellent performance in epoxy, polyurethane, and vinyl resin systems
• Chemically stable under saline and alkaline conditions
• Consistent quality verified through FTIR, XRD, particle size, and BET surface area analysis
