Thermal insulation coatings address "preventing heat transfer", which is a different issue from heat-resistant coatings addressing "the coating itself not burning away"—many projects confuse the two and select the wrong direction. There are currently three main technical lines. The first is aerogel and low-thermal-conductivity insulation coatings: the coating contains low-thermal-conductivity fillers such as aerogel or hollow microspheres, used on external walls of pipes, valves, flanges, pressure vessels and storage tanks, replacing the traditional practice of insulation wool plus metal cladding under hot and cold conditions, reducing heat loss and also used for anti-condensation and personnel burn protection. The second is corrosion under insulation (CUI) coatings: metal surfaces under insulation remain in environments of moisture accumulation and hot-cold cycling for long periods, with corrosion rates far higher than exposed areas, making them high-incidence areas of petrochemical plant failure; CUI-specific coatings must withstand a wide temperature range and resist moisture vapor permeation. The third is solar heat-reflective insulation coatings: high solar reflectance (usually required above 0.70) reflects solar radiation, reducing the surface temperature of storage tanks, pipes, granaries, railcars and roofs by 10–20°C, used to reduce oil product evaporation loss, lower cooling load and suppress internal temperature rise. Selection depends on four parameters: thermal conductivity, solar reflectance, applicable temperature range, and whether hot-cold cycling is required. In application, aerogel products usually require multiple thin coats to form a stable low-thermal-conductivity structure; excessive thickness in a single coat affects insulation performance and adhesion.

This page compiles original-factory technical data sheets by tag. The same model may appear under several tags at once (for example, a water-borne epoxy primer belongs to "water-borne", "epoxy" and "primer"), the more entry points a model has, the more easily it is found by search habits.
