The Indian Space Research Organization has developed a special coating system developed as a high temperature resistant enamel coating. Called ‘HESC-29’, this coating finds application as a high solar emissive topcoat on polymer composite surfaces. It is also used as a high emissive and thermal insulative coating on the PCB sensor cards for specific applications. This room temperature curable, silicone based coating system contains special inorganic fillers, which imparts high emissivity to the system. It can withstand temperatures in the range of 80 to 280 degrees C.
ISRO itself has an use for this compound and requires about 30 to 50kg of this per year. However, this coating has several applications, such as anti-corrosion and weather/ rain proof coating on metallic/ composite substrates. The coating is weather and high temperature resistant and lasts long. It is a two-part resin system. When the two parts are mixed together and coated, curing takes place at ambient conditions. It can be easily coated/brushed on any substrates.
