This is the degree to which a coating will obscure the surface to which it has been applied. Opacity is
measured in a similar way to shade, however opacity, or hiding power, as defined by ISO 2814 involves
measuring whiteness of a known film of test material on both a black (less than 5%) and a white (greater
than 75%, less than 85%) substrate. A full range of opacity test charts are available.
