Application Guidelines

• Surface Preparation:
  • HT300 is designed for steel surfaces pretreated by sandblasting to meet Swedish standard SIS 055900 Sa2.5 or prepared with power tools.
  • All surfaces must be free of grease, moisture, and impurities before sandblasting.
  • For application over inorganic zinc coatings, ensure the surface is dry and free of zinc salts; for sprayed aluminum or zinc steel, ensure the surface is dry and free of contaminants.
• Application Notes:
  • Film thickness: Avoid excessively thick films, as subsequent heat exposure may cause blistering. Diluent TH003 must be added during application to ensure a lower dry film thickness.
  • Full curing of HT300 requires curing at temperatures above 200°C for more than 5 days; otherwise, the paint will exhibit thermoplastic properties.
  • For high-temperature applications, the total dry film thickness of the coating system should preferably not exceed 75 microns.
  • Do not expose the film to heat before it is completely dry (at least 24 hours at 20°C).

Safety Measures

• Pay attention to the warning labels on the packaging containers.
• Use in a well-ventilated environment.
• Avoid swallowing or inhaling paint mist.
• Avoid skin contact. If paint accidentally comes into contact with skin, immediately clean with a suitable cleanser and soap. If paint gets into eyes, rinse thoroughly with water and seek medical attention immediately.
