Sustainable Testing of Paint and Coatings by Vis-NIR Spectroscopy

Sustainable Testing of Paint and Coatings by Vis-NIR Spectroscopy

This white paper describes how Vis-NIR spectroscopy improves testing procedures for various analyses during the formulation and production of paint and coatings in an economic and ecological way.

More strict regulations paired with more complex products have increased testing complexity in the paint and coating industry. Therefore, producers ask for more powerful, safe and sustainable analytical methods. Testing by Vis-NIR spectroscopy is a sustainable and cost efficient alternative to many wet chemical methods. This white paper describes how Vis-NIR spectroscopy improves testing procedures for various analyses during the formulation and production of paint and coatings in an economic and ecological way.

Economical and ecological

Vis-NIR spectroscopy achieves a high throughput by detecting multiple parameters in a single measurement. In addition, it fulfi lls economical as well as ecological criteria. As sample preparation is required for neither liquid nor solid samples and analyses are nondestructive, the need for expensive auxiliary chemicals is eliminated while, at the same time, safety is improved and costs are reduced. Especially for the emerging fi eld of powder coatings that are in better compliance with volatile organic compounds (VOC) regulations, Vis-NIR spectroscopy as a nondestructive, ready-to-use technique shows great promise.
