Leveling test paper

Leveling test paper is used to detect the leveling property of coatings by observing the spreading and contraction of the liquid after it is applied. The principle is based on the wetting balance of the liquid on a specific paper surface, and its function is to evaluate the uniformity of the coating. It is applied in quality control before the construction of inks and coatings.
Selection
When selecting, consider the paper's weight and its compatibility with the liquid absorption for testing fluids, match the surface texture with the required coating thickness, ensure the size fits the experimental apparatus, and maintain chemical stability to avoid reactions with samples. Refer to industry standards to determine the appropriate range of technical parameters.
