Painters must know the drying speed of the paint before painting. Experienced masters often pour a little drier into the paint during construction in winter, so that it can dry and form a film within a few hours. The dry operation time is shortened, and the paint film is smooth, dry and not sticky, which is not only convenient for construction, but also greatly shortens the construction period, and can prevent the undried coating surface from being polluted by dust, smoke, fog, and human body collision. affect the surface quality of the paint film. This kind of substance that can speed up the drying and film formation of paint coating is called drier.
When adding driers to the paint, the appropriate amount of driers and driers should be selected according to the specific requirements of the paint project, the dryness and humidity of the climate, and the variety of the paint. Driers are generally used in oil-based paints and alkyd paints to promote the oxidative polymerization process of drying oils and accelerate the drying of paint films.
When adding drier, special attention should be paid not to damage the thickness and gloss of the surface paint film. Therefore, the last paint, especially light-colored paint, should not be added with drier.
