What is hiding power? How to test Coating hiding power

Definition of hiding power

Brush the paint evenly on the surface of the object, so that the base color is no longer present the minimum amount of paint is the paint hiding power. The smaller the value, the better the hiding power!


Factors of hiding power

In the paint industry, pigments can cover the surface of all coated objects so that they can no longer be exposed through the coating film. The strength of the hiding power of pigments is mainly determined by the following properties:


1. Refractive index, the larger the refractive index, the stronger the hiding power;


2. The ability to absorb light, the greater the ability to absorb light, the stronger the hiding power;


3. Crystallinity, the hiding power of crystal shape is strong, and the hiding power of amorphous shape is weak;


4. The degree of dispersion, the greater the degree of dispersion, the stronger the hiding power.
