Outdoor Weather-Resistant Powder Coatings

Outdoor pure polyester weather-resistant powder coating is a high-performance coating specifically designed for outdoor environments, with pure polyester resin as the main film-forming substance, prepared through a special formula and production process. The coating has good weather resistance, corrosion resistance, mechanical properties and decorative properties, and is widely used in outdoor fields such as construction, transportation, municipal facilities, etc.

Key features

  • Excellent weather resistance: can resist the erosion of natural factors such as ultraviolet rays, rain, wind and sand for a long time without fading, powdering or cracking, and maintain good appearance and performance;
  • Excellent mechanical properties: The coating is tough and has strong adhesion, with good impact resistance, wear resistance and flexibility, capable of withstanding stress such as collision, friction and bending during daily use, and is not prone to damage;
  • Rich decorative effect: A wide range of colors available, including glossy / matte / sand-textured / drape textured finishes and effects. Pearlescent and metallic colors can be customized according to customer requirements;

Application

Application areas
Building profiles, construction machinery, agricultural machinery, automotive parts, garden furniture, garden facilities, sports equipment, etc.

Application Instructions
  1. Curing conditions: 200 °C / 10-15 minutes; To ensure uniform curing of the coating, it is best to have a uniform temperature distribution in the baking oven; And control the curing temperature and time reasonably according to the condition of the workpiece.
  2. Pretreatment: Workpieces must undergo pretreatment before spraying. Aluminium alloys should comply with the requirements of Chapter 4 surface pretreatment in GB/T 8013.3, and steel and its alloys should comply with the requirements of Standard ISO 12944-4.
  3. Workpiece hanging: When hanging workpieces, hang them reasonably according to the shape and thickness of the workpieces to increase the powder coating rate and yield; Also pay attention to keeping the spraying system and the surrounding environment clean to prevent different brands of powder coatings from mixing in and affecting the surface effect of the coating film.
  4. Powder coating: Select reasonable process parameters. The environment for powder coating should preferably have a temperature and humidity control system. The optimal temperature for powder coating is 15-25 °C, and the relative air humidity in the powder coating chamber should preferably be 45% to 55%.
  5. Coating thickness: The coating thickness should be 50μm or more. If anti-corrosion effect is required, the film thickness should be appropriately increased and uniformity should be controlled, otherwise it will affect the performance and appearance of the coating film.
  6. Color variation: During the formation of the coating, the color is slightly affected by process conditions such as temperature and thickness. It is recommended that users conduct tests before application to achieve satisfactory results.
