Note: There are two types of objects: transparent and non transparent, Anti condensation coating There are also two categories. （1） Transparent material Anti condensation coating, often called Antifogging coating Or anti blur paint. At high temperature, tiny dewdrops (water drops) condense on the surface of glass or transparent plastic, and the dewdrops are dense, and the surface of transparent material becomes blurred. In order to prevent this phenomenon, anti fog paint is usually used. The antifogging coating is usually composed of three parts, namely hydrophilic polymer, cross-linking agent and surface active agent , wherein the main body is a hydrophilic polymer, which absorbs moisture; In order to enhance the water resistance and friction resistance of the resin, crosslinking agent is introduced; Surfactant is added to improve surface wettability and anti fogging property. (2) Non transparent materials (such as reinforced concrete , cement, wood, plastic, etc.). Composition and types: emulsion type (made of emulsion liquid, dispersant, mildew inhibitor, diatomite, vermiculite, etc.) solvent type (made of synthetic resin as alkyd resin , solvent, mildew inhibitor, diatomite and vermiculite) and two-component polyurethane foam Paint. After the film is formed, it is a porous coating with good air permeability and anti condensation performance. It is suitable for places with high temporary humidity.
