Leveling agent species added in oily paint and different effects of various coating levelling agent

Coating construction, there is a flow and drying film-forming process, and gradually form a coating of a flat, smooth, uniform. The coating can achieve the smooth property, called leveling. Shrinkage is one of the characteristics of coating defects in leveling and produced film process. In the actual construction process, because the leveling is not good, brush marks the emergence of the brush, appear orange peel roll marks, spraying is generated when the roller coating, in the process of drying shrinkage, accompanied by the emergence of the pinhole, sagging and other phenomena, are called leveling is bad, these phenomenon reduces the decoration and the protection of functional coating. Many factors influence the coating leveling, the volatilization of solvent gradient and solubility properties, coating the surface tension, the wet film thickness and surface tension gradient, coating rheology, construction technology and environment, one of the most important factors is uniform surface tension surface tension gradient of surface tension, surface coating of the wet film films produced in the process and the wet film. Improve the coating leveling need to consider adjusting the formula and adding appropriate additives, paint with suitable surface tension and reduce the surface tension gradient ability.
