Vikram Sarabhai Space Centre has developed a good number of specialty coatings to meet the specific requirements in Launch Vehicles and Satellites.These coatings may also find various industrial applications. HESC/CSNM-29 is one such special coating system developed as a high temperature resistant enamel coating. This coating finds application as a high emissive topcoat on ablative surfaces. It is also used as a high emissive and thermal insulative coating on the PCB sensor cards for GPS Radiosonde studies. This room temperature curable silicone based coating system contains special inorganic fillers, which imparts high emissivity to the system. Other applications could include anticorrosion and weather/ rain proof coating on metallic substrates. The coating is weather and high temperature resistant and lasts for long.
