Problems solved by technology

[0003] In addition, new coatings such as glass energy-saving coatings, radiation cooling coatings, sun-proof and heat-insulating coatings, high-temperature-resistant sealing coatings, and high-efficiency anti-fouling solar heat-absorbing coatings developed in recent years have also brought new energy to the coatings industry on the "low-carbon" road. There are new opportunities for development, but there are still deficiencies in the weather resistance, especially corrosion resistance, of high temperature resistant coatings for higher temperatures such as coatings above 600 degrees
