Throughout the 1990's, the color trend was toward finer and brighter metallic effects. Though "fineness" and "brightness" typically trend in opposite directions when developing aluminum pigments, Silberline engineered the flakes in SPARKLE SILVER Premier pigments to have more uniform surfaces, smoother rounded edges and controlled particle size distribution. This unique "silver dollar" technology gave designers finer and brighter aluminum pigments exhibiting cleaner polychromatic effects. Silberline's SPARKLE SILVER Premier pigments are available with median particle size ranges between 12 to 34 microns.
