Opacity Grid Paper

Covering power grid paper is a standard test paper printed with black and white grids, used to measure the covering ability of coatings. The principle involves evenly applying the coating onto the grid paper and assessing the covering performance by observing the extent to which the black and white grids are concealed. Its function is to provide a reference for the covering effect in the production and use of coatings, and it is applied in the adjustment of coating formulations and quality control.
Selection
When selecting a hiding power grid paper, it is essential to confirm that the size of the black and white grids complies with the testing standards, the paper thickness is uniform and resistant to deformation, and the printed grid lines are clear and free of burrs. Consider the compatibility of the coating type with the paper’s liquid absorption and the stability of the paper under the test environment's humidity. Verify the metrological certification documents provided by the manufacturer to ensure the validity of the test results.
