Varnish functionalised with graphene that dissipates heat from surfaces. One of the main features of graphene is that it is a good thermal conductor, resulting in fast and uniform diffusion of heat across the surface, which dramatically reduces the temperature. Huge potential as a substitute for thermal pastes and a transparent element to dissipate heat in LED bulbs and household appliances (increasing their lifespan). Besides being an excellent dissipater of heat, this coating has good adhesion and an anti-corrosive function.
