Paint Opacity Test Paper

The paint opacity test paper determines the hiding power of paint by comparing the coverage effect of the coating on a black-and-white grid background. During testing, the paint is evenly applied to the test paper, and the degree to which the black-and-white grid is covered is observed. It is used in paint production and application processes to control the hiding performance of coatings.
Selection
When selecting, consider the flatness of the test paper substrate, the clarity of black-and-white grid printing, and the ink absorption of the paper. Match the paper thickness according to the type of paint being tested: choose low-absorbency paper for water-based paints and solvent-resistant paper for oil-based paints. Pay attention to the color difference and batch stability of the test paper to ensure reliable comparison results.
