Paints containing carbon-based nanomaterials for enhanced thermal conductivity confer greater heat dissipation to a surface. Nanomaterials also lead to higher coating-substrate adherence and are more corrosion-resistant.
These paints are ideal for surfaces requiring heat dissipation, heat exchangers, surfaces on radiators, IT equipment, kitchen appliances, laboratory equipment, etc., and surfaces exposed to aggressive environments.
Carbon nanomaterials increase the thermal conductivity of a paint by 100% over untreated paint, increasing heat transmission. Its use on metal surfaces facilitates heat dissipation, increasing cooling by 40%, a characteristic which is extremely useful in applications requiring cooling or where overheating must be prevented.
Not only the type of nanomaterial, but also its morphology and distribution in the paint determines the paint’s thermal conductivity and rate of heat transfer. The greater the nanomaterial dispersion homogeneity, the greater the heat transfer rate.
In addition, when a metal surface painted with additivated paint is immersed in a corrosive medium, such as a solution of NaCl, the nanomaterial’s presence slows down the separation of paint from the surface and rust appearance.
The images below compare the effect of exposing a metal surface painted with non-additivated paint to a corrosive medium, and a metal surface painted with a paint containing carbon nanomaterials.
