Technical Field

Its unique microporous structure and ultra-light properties enable aerogel to exhibit excellent performance in many fields. Aerogel coating applies this unique material to coatings to achieve functions such as heat insulation, sound insulation, and fire prevention. With the continuous advancement of science and technology, traditional coatings are difficult to meet the needs of modern industry and construction in some aspects of performance. Aerogel coatings have gradually become the first choice for some special applications due to their extremely low thermal conductivity and good mechanical properties. For example, in industries such as aerospace, construction, automobiles, and electronic equipment, aerogel coatings provide better protection and insulation for products.
