Anti-Corrosion Graphene Additive

Anti-Corrosion Graphene Additive – High-Performance Material for Protective Coatings

Product Overview
This graphene-based additive is specifically designed for use in high-performance anti-corrosion coatings. Its unique two-dimensional structure and high specific surface area enable the formation of a dense physical barrier layer that effectively blocks the penetration of corrosive media (water, oxygen, ions) to the metal substrate. In zinc-rich primers, it activates zinc particles and provides a synergistic effect through its excellent electrical conductivity, significantly improving cathodic protection while allowing reduction of zinc dust loading.

Key Performance Features

• Physical barrier: Forms a dense, impermeable layer due to high specific surface area and ultra-thin planar structure, greatly enhancing corrosion resistance.

• Zinc activation: Enhances the electrical connectivity between zinc particles, improving the efficiency of cathodic protection and enabling lower zinc dust content in the coating.

• Adhesion improvement: Increases coating adhesion to the substrate, reducing film thickness while maintaining or improving performance.

• Wear resistance: Makes the film more durable and extends service life.

• Corrosion resistance: Significantly enhances overall anti-corrosion properties, even at reduced zinc levels.

Applications

• Suitable for all types of heavy-duty anti-corrosion coatings, including:

  • High-zinc epoxy primers (chromium-free formulations).

  • Dacromet (zinc-aluminum flake) coatings.

  • Other zinc-rich or barrier-type protective systems.

Handling and Storage

• Wear appropriate protective clothing and gloves to avoid direct skin contact. In case of contact, wash immediately with plenty of water.

• Use proper dust control measures (ventilation, dust collectors) to avoid inhalation.

• Handle with care to prevent damage to packaging.

• Store in tightly sealed containers in a cool, dry, well-ventilated area, away from ignition sources, strong reducing agents, and flammable materials.

• Keep away from moisture – product is moisture-sensitive. If moisture absorption occurs, dry at 80°C for several hours with outer packaging removed (keep inner paper valve intact) before use.

• Use promptly after opening; reseal unused portions tightly.

Transport

• Protect from sunlight, rain, and physical damage.

• Keep away from heat sources and corrosive materials during transport.

• Handle gently to avoid package rupture.

Shelf Life
Long-term storage is possible under recommended conditions. For moisture-sensitive applications, drying before use is advised if strict moisture control is required.

Packaging
Available in standard packaging sizes (e.g., 1 kg, 5 kg, 25 kg containers) and custom packaging upon request.

Quality Assurance
Each batch is tested for particle size, specific surface area, electrical conductivity, and dispersion performance to ensure consistent coating performance.
