The leveling of Coating refers to the self-leveling ability of Coating during construction. It indicates whether Coating can be evenly and evenly distributed on the coating surface after construction to form a smooth and uniform surface. The better the leveling, the smoother the film surface and the better the Appearance effect.
Coating leveling is affected by many factors, including Coating viscosity, surface tension, drying time, temperature, Humidity, etc. If the viscosity of Coating is too high or the surface tension is too large, it will affect the self-leveling ability of Coating. In addition, too long drying time or too large changes in temperature and Humidity will also affect the leveling of Coating.
In order to improve the leveling of Coatings, leveling agents are usually added. A leveling agent is a surfactant-acting chemical that reduces the surface tension of Coatings and promotes the self-leveling ability of Coatings. However, excessive use of leveling agents can also affect the performance of Coatings, so it is necessary to add an appropriate amount according to the specific situation.
