Key Features and Technologies

• Excellent temperature resistance: Withstands high temperatures up to 160°C and low temperatures down to –50°C.
  
• Flame retardancy: UV89 possesses vertical flame-retardant properties and is UL-certified (E516495).
  
• Electrical performance: Passed the UL high-temperature aging test at 140°C for 1000 hours (UL E516495).
  
• Electrical insulation: Provides high surface and volume resistivity, offering reliable insulation protection for circuit boards even under humid conditions.
  
• Coating thickness: The dry film thickness of UV89 can be controlled between 50–300 µm, and different viscosities can be customized according to customer requirements.
  
• Environmental resistance: Once cured, the UV89 coating offers excellent resistance to mechanical impact, sediment, humidity, dust, corrosive gases, and harsh environmental conditions.
  
• Chemical resistance: Outstanding resistance to moisture, weak acids, weak alkalis, and solvents. It performs well in sulfurization tests and is suitable for applications requiring long-term durability, such as automotive and marine environments.
