There are a lot of equipment that needs to operate in high temperature environment. The temperature above 200 degrees basically belongs to high temperature environment. The high temperature paint temperature range on the market, silicone temperature resistance is 400 degrees, epoxy temperature resistance is about 160 degrees, fluorocarbon temperature resistance. The temperature resistance of polyurethane is about 280 degrees and the temperature is about 160 degrees. The temperature resistance value often does not reach the maximum bearing range of the substrate. For some cases that require a temperature resistance of more than 500 degrees, these paints do not consider environmental issues for the time being. Can not pass, and the user's working conditions are often not a single requirement of temperature resistance, so high temperature resistant coatings can be divided into many types, such as: high temperature resistant anticorrosive coatings, high temperature resistant thermal insulation coatings, high temperature resistant insulating coatings, high temperature resistant wear resistant coatings High temperature resistant far-infrared coating, high temperature resistant thermal conductive coating, high temperature non-stick coating, high temperature resistant oxidation coating ... The conditions of each workpiece are different. The substrate itself has a certain high temperature resistant function, but May not have anti-corrosion, insulation and other properties, other functions combined with high-temperature coatings can just make up for and increase product use value.
Therefore, although the high temperature resistant coating cannot increase the temperature resistance limit of the substrate itself, it has a certain protective effect on the substrate in a high temperature environment.
