Objective mottling measurement of effect coatings
Mottling is an undesirable paint defect of lightness variations which is most obvious on light effect finishes. Typical causes can be a disorientation of the metallic flakes or film thickness variations of the basecoat. The BYK-Gardner mottling meter, cloud-runner objectively evaluates mottling as we see it and characterizes the mottles by their size and visibility. As a result, differences can be easily distinguished and target values can be specified for batch approval and process control. The small and ergonomic design of the mottle meter allows measurement in the lab for paint approval as well as in the line to evaluate process variations.
