Orange Peel measurement on high to semi gloss surfaces

BYK-Gardner - worldwide partner of the automotive, paint and plastic industries for quality control of color, appearance and physical properties - is introducing a new instrument to objectively measure the surface quality after each paint process step: the wave-scan dual.

Currently, appearance is measured after clear coat application. But it is known that substrate quality can telegraph through the clear coat and cause a “fuzzy” appearance.The substrate can be rough steel, e-coat, primer surfacer or basecoat. As e-coat and primer coatings are often semi gloss finishes, so far the only way to measure was by applying a clear tape – highly user dependent and meaningful only for long wave values.

Now, with the wave-scan dual, it is for the first time possible to control the surface quality after each paint process step and establish specifications for each coating layer. The new instrument measures long wave and short wave as well as distinctness-of-image (DOI). DOI is an objective measure for brilliance and gloss, independent of the paint system and the curvature of the surface. Additionally, the structure spectrum offers detailed information and assists in optimizing and troubleshooting.

The wave-scan dual has a good correlation to wave-scan DOI on high gloss surfaces and to the tape method or profilometer results on medium gloss surfaces. It is small and of light weight. Operation is easy due to the scroll wheel and a large display shows complete statistics with saving in selectable memories. The instrument comes with a docking station for recharging the battery pack and for transferring the saved data to the PC via USB. The auto-chart software offers flexible analysis and a professional documentation in Excel®.
