Reflectance haze

WebThe haze-gloss is an objective tool to measure matte to high-gloss surfaces by offering three gloss geometries (20°, 60°, 85°) as well as reflectance haze measurement in one unit. However, to measure gloss and haze the TiO 2 has to be incorporated in the coatings system and a drawdown has to be made. WebHaze (HU) Haze causes a drop in reflected contrast and causes ‘halos’ to appear around the reflected light sources, dramatically reducing the visual quality. In accordance with ASTM D4039 haze is defined as the numeric difference between the specular reflectance at 60degree and 20degree. This is expressed in Haze Units (HU).
