Epoxy polyamide primer

Epoxy polyamide primer

This paint protects the inner surfaces of tanks, pipelines, ship decks, military equipment, various petrochemical and refinery equipment against corrosive agents and foreign materials, and in painting concrete, steel, cement, etc. surfaces as paint The final is used using a variety of primers and intermediate paints (except alkyd group paints). Due to the lack of resistance of the epoxy group to ultraviolet (UV) sunlight, this product has limited performance in long-term environments.

Description of solvent-free sanitary epoxy primer

Its properties include:
  1. Very good corrosion resistance
  2. High chemical resistance
  3. High abrasion resistance and hardness
  4. Excellent water and moisture resistance
  5. Good adhesion to steel surfaces
  6. Applicable with thicknesses over 200 microns
  7. Surface impermeability
  8. Designed for health systems
  9. Shine and excellent appearance

Uses

This coating is used alone as the final layer of sanitary epoxy systems and drinking water to protect the surfaces against corrosion and microbes. Due to the high solid percentage of paint with a spraying step, thicknesses up to 500 microns can be achieved. Its uses include:
  • Drinking water tanks
  • Water transfer pipes
  • Sanitary equipment
  • Industrial Drug Making Machines
  • Food Equipment
  • Food storage cells
  • Sanitary ware containers
  • Clean hall and operating room flooring

Surface preparation

Painted surfaces – These surfaces must be completely clean and free of any grease and other contaminants. Before painting, the surface should be completely dry and if a long time has passed since the application of the undercoat, a suitable roughness should be created by soft sanding on the surface. Steel surfaces – Wash the steel surface with a suitable solvent to remove grease, salt and any other contaminants. De-rust and create profiles on surfaces by various methods such as sand blasting up to 2.5 degrees Swedish or by mechanical tools up to ISO-ST3 degree. In metal structures and welded points and corners should be smooth and polished and free of any appendages and sharpness. After de-rusting and creating a profile, remove the particles from the preparation and other contaminants from the surface with a pressure of air free of moisture and grease and with the method of vacuum and thoroughly clean. Note that the application of the first layer (primer) should be done no later than two hours after preparation. Concrete surfaces – If the concrete is fresh, it must be 28 days after the concrete has been applied (the concrete surface is completely dry). If the concrete is old, the surface must be washed with fresh water to remove contaminants such as salts, grease, dust and Dust, loose and unstable particles, etc. from its surface

Description of epoxy polyamide primer

Epoxy primer is a two-component epoxy-poly-hope primer. How hard it is is the evaporation of solvent and the reaction between the components, and among its properties are:
  1. High flexibility
  2. High chemical resistance
  3. Abrasion resistance and high hardness
  4. Excellent water and moisture resistance
  5. Excellent adhesion to steel surfaces
  6. Applicable over 100 microns thick

Uses

This coating is used alone or as a primer for epoxy and polyurethane systems to protect surfaces in industrial, chemical and marine environments. Due to the high solid percentage of paint, a high thickness can be obtained with one spraying step. Among its uses are:
  • Drilling rigs and installations
  • Facilities and equipment in direct contact with moisture
  • Exterior parts of storage tanks
  • Refineries, power plants and chemical plants
  • Coastal and offshore metal structures and installations
  • Structural steel structures, pipes, bridges and offshore installations
