Heat Exchange Paint

This is a revolutionary heat reflection and insulation concept!

When sun rays strike the paint's surface, part of the infrared light changes into heat energy, breaks up, and moves in the paint's surface. Within the paint is a special material which triggers almost all this heat energy to be converted into electric energy and released from the surface.


  1. It's possible to have deep coloured paint.
  2. If the paint surface gets damage, for example dirt, wear or a flaw, the effectiveness of the paint is not reduced.
  3. The paint is not glossy so it is cheap and it's possible to use it with a wide range of resins.
