Effect of surface gloss acrylic polyurethane paint reasons

Effect of acrylic polyurethane lacquer paint surface gloss reason
1, in paint pigment to binder ratio impact on the film gloss. Since the pigment particles in the film weakening causing specular reflection gloss reduction, but also with a pigment volume concentration (P.V.C) increases the gloss decreased.
2, the extent of absorption and reflection of different colored pigments to light, since the black light is completely absorbed, and totally reflected light white paint, black paint so than the white paint shows a high gloss.
3, the level of the film surface gloss, smoothness and roughness depends not only on the film surface, the angle of incidence of the light will also affect the gloss, the incident angle, the higher the intensity of reflected light.
4, in the gloss region, visual luster and instrument measuring the gloss approximate linear relationship; and in the high-gloss region, due to the sharpness of the reflected image determines the visual gloss is often lower than the instrument measuring the gloss; in a low gloss region, due to the pigment (a matting agent ) different amounts and the roughness of the film surface, the instrument will make the visual luster higher than the measured results.
