Paint film hiding power chart

The paint film opacity chart is a test substrate with alternating black and white squares. It is used to evaluate the hiding power of paint by observing the extent to which the paint covers the black and white squares after application, and is employed in paint production and construction to control the hiding effect.
Selection
When selecting, consider the substrate material for flatness and durability, clear and distinct boundaries between black and white grids, dimensions that meet testing standard requirements, and a clean, uncontaminated surface to ensure accurate and reliable test results.
