Opacity chart for paint

Hiding power chart paper for colored paint is a standard black-and-white grid test paper used to determine the hiding ability of coatings by observing the disappearance of the black-and-white grid after the paint is evenly applied. Its principle is based on the paint film's ability to conceal the color of the substrate, enabling quick assessment of hiding performance during paint production and application to avoid substrate exposure or excessive coating.
Selection
When selecting, ensure the paperboard thickness is uniform, the surface is smooth without burrs, and the black and white grid boundaries are clear and distinct. The material should be resistant to solvent penetration, and the dimensions must comply with standard specifications. Match the paperboard base material according to the type of coating being tested, and ensure stable lighting conditions in the testing environment. Before use, verify that the paperboard is free from creases, stains, or damage.
