Metal components exposed to high temperatures require reliable surface protection. Choosing the right high temperature powder coating helps improve coating durability while maintaining surface performance in demanding environments.

LEKA high temperature powder coating combines heat resistance, weathering performance and surface protection. It is suitable for selected metal applications such as engine components, exhaust systems, BBQ grills and radiators.

Key Benefits of High Temperature Powder Coating

High Temperature Resistance：

Designed for elevated-temperature applications, this powder coating achieves a laboratory high-temperature resistance test result of up to 450°C, making it suitable for evaluating selected high-temperature metal components.

Excellent UV and Weather Resistance：

With UV stability and weathering performance, the coating achieves over 75% gloss retention after 168 hours of UVB exposure, according to ASTM G154-2016.

Durable Surface Protection：

Laboratory testing demonstrates

  • Salt spray resistance: 500 hours, maximum 1 mm blister.
  • Humidity resistance: 500 hours, maximum 1 mm blister.
  • Adhesion: Class 0.
  • Impact resistance: No cracking at 20 In·lbs.

These properties provide reference data for evaluating coating performance in industrial environments.

Applications of Heat Resistant Powder Coating

High temperature powder coating can be evaluated for various metal products, including:

  • Engine Components: For selected metal parts exposed to elevated temperatures.
  • Exhaust Systems: For metal components requiring heat-resistant surface protection.
  • BBQ Grills: For metal grill components exposed to heat and outdoor conditions.
  • Radiators: For metal components requiring thermal and surface protection.

Actual suitability depends on operating temperature, substrate, pretreatment and application conditions.
