Application Guidelines

Surface Preparation
WH-EZ072 is designed for direct application on steel surfaces pre-treated by sandblasting to Sa2.5 grade in accordance with Swedish standard SIS055900. All surfaces must be free of grease, moisture, or other contaminants before sandblasting. For any questions, contact…
Mixing and Dilution
As a two-component product, WH-EZ072 requires strict proportional mixing. First, stir the base material until smooth and uniform (no more than 2 minutes). After the base material is uniform, slowly and continuously add the curing agent and stir for 3 minutes. Allow a 1-2 minute induction time before application. Dilution is generally not required or recommended, as excessive dilution may negatively affect coating application and appearance. A variable-speed electric stirrer is recommended. Avoid over-stirring, as this may accelerate curing and reduce pot life. Higher temperatures shorten pot life, while lower temperatures extend it.
Application
WH-EZ072 can be applied by conventional spraying or airless spraying. When using airless equipment, a Graco 30:1 pump with a nozzle size of 0.43-0.58 mm is recommended to ensure smooth material flow. To achieve optimal coating results, ensure equipment and fluid lines are clean and free of water and solvents. Maintain a recommended spray angle of 40°-70° for uniform film thickness. For roller application, use new short-fine nap rollers.

Safety Precautions

  • Warning: May cause eye and skin irritation. Vapors may cause respiratory irritation in sensitive individuals. May cause skin allergic reactions.
  • Avoid inhaling vapors. Do not contact eyes or skin. Use appropriate eye, ear, and skin protection, as well as a suitable respirator to prevent potential respiratory irritation.
  • Thoroughly wash skin with water after use. Consult a physician if discomfort occurs. Wash clothing before reuse.
  • In case of respiratory arrest, perform mouth-to-mouth resuscitation and seek medical attention immediately.
  • If contact with eyes occurs, rinse immediately with water for at least 15 minutes and seek medical help promptly.
