Basic parameters

• Color Gray
• Proportioning main agent: Curing agent =25:3
• Construction brush coating, spraying, rolling coating can be
• It is composed of epoxy resin, zinc powder and graphene as the main raw materials, thickener, filler, auxiliary agent, solvent and curing agent.
• 
• Product features
• Excellent anti-corrosion properties. Epoxy graphene zinc powder primer using graphene sheet layer structure, can form a dense physical insulation layer, significantly improve the corrosion resistance of the product. Graphene's high specific surface area, excellent electrical conductivity, strength, toughness and shielding properties make it excellent in the field of anti-corrosion coatings.
• Improve the utilization of zinc powder. The traditional epoxy zinc-rich primer has some problems, such as low zinc powder utilization rate, high addition amount and easy cracking of thick coating. By adding graphene to epoxy zinc powder primer, the conductive properties of graphene can be used to connect zinc powder particles to form a conductive network at a lower zinc powder content, thereby improving the utilization rate of zinc powder and enhancing the overall anticorrosion ability of the coating.
• The salt spray resistance is improved. In the epoxy graphene zinc powder primer, the shielding effect of graphene can delay the penetration of corrosive media and reduce the electrolyte concentration in the coating, thus delaying the electrochemical corrosion consumption of metal zinc. This allows the metal zinc in the coating to play a cathodic protection role for a long time, and significantly improves the salt spray resistance of the coating.
• Environmental performance. Because the amount of zinc powder in the epoxy graphene zinc powder primer is reduced, the zinc oxide mist generated during the welding process is also reduced, reducing the impact on the environment and making it more environmentally friendly.
• Excellent comprehensive performance. Epoxy graphene zinc powder primer not only has the cathodic protection effect of epoxy zinc-rich coating and the shielding effect of glass flake coating, but also has good toughness, adhesion, water resistance and hardness. These comprehensive properties make the graphene zinc powder primer have wider applicability and higher cost performance while ensuring the anti-corrosion effect.
• Thermal stability and chemical stability. Graphene has excellent thermal and chemical stability and is able to remain stable under high temperature conditions as well as in corrosive or oxidizing environments, further enhancing the durability and reliability of the coating.

  Construction notes:

  • This product is like most zinc-rich paints, long-term exposure to the paint film will appear zinc salt, must be thoroughly cleaned before applying the next paint, otherwise it will affect the adhesion between layers.
  • The temperature of the substrate must be above 3 ° C above the dew point, and when the temperature of the substrate is below 5 ° C, the paint film is not cured and should not be constructed.
  • In the high temperature season construction, easy to occur dry spray, in order to avoid dry spray can be adjusted to dry spray until the diluent.
  • This product should be used by professional painting operators according to the product packaging or the instructions in this manual.

  Steel surface:

  • Must thoroughly remove oil, rust, etc., to achieve the rust removal standard Sa2.5, the roughness of 30um-75um; Adopt manual rust removal method, need to reach the rust removal standard St3 level.

  Concrete surface:

  • Concrete surface should be flat, dry, no seepage floating and water. The base that has been polluted by grease and chemicals can be washed with detergent, lye or solvent, and can also be treated by fire baking, steam blowing, etc., but it must not damage the base.

  Precautions

  • Products should be stored in a cool and ventilated place to prevent rain, direct sunlight, avoid collision, need to isolate the fire source.
  • The construction site is strictly prohibited fireworks, painters should wear glasses, gloves, masks, etc., to avoid skin contact and inhalation of paint mist.
  • All work of coating and use of this product must be carried out in accordance with various relevant national health, safety and environmental protection regulations and standards.
  • If you have any questions about the use of this product, please contact our technical service department.
