High gloss, deep finishing, smooth and homogenous are what consumers look for in a high quality product. To ensure these attributes in finishes, manufacturers ensures that the coating they use are free from orange peel and haze.
Beside gloss evaluation, visual attributes like Peak Specular Reflectance (RSPEC), Haze, Reflected Image Quality (RIQ), Distinctness of Image (DOI) and Goniophotometeric Curves (GS) provide insight into a finish quality.
Potential causes of poor visual quality can be identified by these attributes helping manufacturers to troubleshoot coating recipe or formulation, substrate quality, application techniques and environmental problems during curing or drying.
