Developments in Thin Milled Aluminum Flake Technology for Water-Based Coating Systems
Recent popularity of thin milled aluminum flakes has stimulated development activities to push the limits of color and performance of these pigments in water-based systems. This presentation will explore the multiple options for surface treatments of thin milled aluminum flakes and the effect these treatments have on final color, sparkle, opacity, gassing, dispersion, shear, and chemical resistance in both interior and exterior coatings. Visual assessment and instrumental analysis of coatings containing these pigments will be discussed. Also addressed will be the options available for pigment carrier and delivery form, such as paste, powder and solvent-free granules, designed to perform in the most demanding low-VOC coating systems. Proper dispersion and formulating practices will also be explored.
