QUALITY CONTROL TESTING of Titanium Dioxide Industrial Coating Bases

[...]it's essential. Whiteness meters generally adopt RGB 0/45 optical filter structure, which is limited in the information it provides (Figure 1). Because of this, whiteness meters provide only whiteness data calculated with tristimulus values and cannot provide reflectance data, which limits options for other testing calculations that may be desired and could have otherwise been calculated using reflectance curves. With a D/8 geometric angle and dual-beam-type benchtop spectrophotometer, coatings plants also enjoy many benefits beyond inter-instrument agreement, including ease of sharing data between stations, highly accurate and repeatable measurements, increased data reliability thanks to regular onsite calibration and maintenance services, and the ability to run multiple tests on the same equipment (Figure 2). Because of the increased accuracy of data, measurements from spectrophotometers can be compared against standards, without the need to conduct parallel tests, effectively saving time and money in the process.
