Film hiding power black and white cardboard

The hiding power of a paint film is determined by comparing the color difference of the coating on black and white paper cards, which assesses the paint's ability to conceal the underlying surface. The principle is based on the difference in light reflection between black and white backgrounds. Its function is to quantify the opacity of the coating, and it is applied in paint formulation and the verification of construction effects.
