At Stand 7-205, BYK Gardner is showcasing its new cloud runner, which objectively measures “cloudiness”. Cloudiness (mottling) is lightness variations that are most obvious on light metallic finishes. They are considered a paint defect and can be caused by formulation incompatibilities as well as variations in application parameters. For example, film thickness variations of the basecoat or flake disorientation can lead to various cloud sizes resulting in a non-uniform appearance.

Also featured is the new BYK-mac, which objectively measures total color impression. Today’s effect finishes can no longer be described only with multi-angle color measurement. The total color impression changes with viewing angle and lighting conditions. Depending on the type of effect pigments used, more or less intensive sparkling effects can be seen under direct sunlight, while under cloudy sky, the finish looks very fine or coarse. The goal is to have a uniform look under all conditions and obtain measurement data that help to optimize the harmony.

The new micro-gloss gloss meters are also on display. These have improved continuous and difference modes and transfer data with a USB cable interface or wirelessly via Bluetooth®.
