TimescoatingTM CNTs thermal radiation water-based coating
Product description
     Carbon nanomaterials(CNT,graphene,etc),with high thermal conductivity and high radiation coefficient, is the ideal functional filler in thermal radiation coating.

    In order to improve heat dissipation performance of metal surface and show high thermal conductivity,strong radiation ability and excellent mechanical properties of carbon nanotubes, we develop a kind of  environmental coating-CNTs thermal radiation water-based coating.

      Electronic components produce too much heat. In order to dissipate heat quickly, we usually use metal heat sink. But because of the low thermal radiation coefficient of metal surface, the heat gathered on the surface of the metal is difficult to send out in the absence of convection heat transfer. Recently, improving the heat radiation performance of metallic materials by coating technology is an important way to increase heat dissipation efficiency. With the rapid development of the electronic industry today , heat radiation coating is widely concerned.
     CNTs and graphene are known as the blackest material in the world, having a large specific surface area and being one of the best heat conducting materials known in the world. Its radiation coefficient is close to 1.
     Nano-carbon thermal radiation water-based coating has remarkable characteristics, including strong radiation capability, thin coating and low thermal resistance. It can stimulate resonance effect of the surface of the metal radiator, improve the efficiency of the far infrared emission significantly and accelerate the rapid dissemination of the heat from the heat sink surface. It is also suitable for heat dissipation of film, metal substrate, LED lamp base and electrical enclosure.
