Unsaturated polyester lacquer is also a recently developed type of coating, which is divided into air-drying unsaturated polyester and radiation-curing (light-curing) unsaturated polyester. The main advantage is that it can be made into a solvent-free paint. A thick paint film can be obtained by one brushing. The coating temperature is not high, and the paint film has a good decorative effect. The paint film is tough and wearable and easy to maintain. The disadvantage is that the shrinkage rate of the paint film is large when curing, and the adhesion to the substrate is prone to problems. The air-drying unsaturated polyester generally needs to be polished, the procedure is more cumbersome, and the radiation-curable unsaturated polyester has higher requirements on the coating equipment. High, not suitable for small production. Unsaturated polyester paint is mainly used in furniture, wooden flooring, metal anti-corrosion, etc.
