Heat dissipation carbon coating paste

Core technology and characteristics

  • Carbon coating composite material is a type of coating paste with excellent heat radiation properties, where carbon is uniformly sprayed onto an organic binder
  • It may be applied onto heat sinks of electronics or high-efficiency lamps to enhance their heat radiation capacity
  • Due to the high heat-radiation carbon materials used, the paste has excellent heat emission and heat transfer properties
  • Excellent corrosion resistance against water, salt, acid, alkali, etc.

TYPE: two-liquid type (mixture of main and curing agents) / color and gloss: glossy black / curing conditions: let dry at room temperature, then cure at 150℃ for 30 minutes
