Enova thermal additive from Cabot has been developed mainly for coating metal surfaces that need insulation. The limited shape, size and access of the traditional insulation techniques make it difficult for applications in complex and expansive regions of exposed metals.
Cabot’s scientists have discovered that the application of the Enova-based 1 mm coating over a metal surface heated to 200°C prevents heat burns within 5 sec. Thus, it meets the European and US testing standards for safe-touch temperature. Similarly, the coating added with the thermal additive can be used for cold surface insulation. It helps prevent freezer burns and decreases the power required to maintain the contents in cold conditions.
The Enova additive can be included during formulation or while applying the coating. It does not produce impact on the viscosity of the surface coating.
Cabot’s Enova comprises aerogel, which is a solid particle containing over 90% air trapped inside an amorphous silica network. When the additive is added in water-borne formulations, a 7 to 10 times higher thermal conductivity can be achieved compared to conventional paint.
