Improving paint and coating formulations

Paints and coatings are highly complex multi-component systems that pose many challenges for the formulation chemist. Ongoing control of raw materials and final formulations is essential for ensuring product quality and customer satisfaction, while an in-depth understanding of physical properties is necessary to devise new formulations.

This white paper discusses these challenges, and explains how obtaining information on the constituents of paint at the molecular and particle level using the techniques of X-ray fluorescence (XRF), X-ray diffraction (XRD), laser diffraction (LD), electrophoretic light scattering (ELS), gel permeation chromatography (GPC) (more generally known as size exclusion chromatography (SEC)), and particle image analysis can ultimately lead to better product performance, streamlined operations, and greater value to the business.
