Application: Aerogel coating is a light, hydrophobic, heat-insulating silica aerogel powder as the main raw material, using a special process to evenly disperse in the thick water In the coating medium, the prepared slurry. On the basis of retaining the original performance of the thick coating, the coating improves the index of high-efficiency heat insulation and effectively solves the dust problem of the aerogel during transportation and use.
