fine particle pigment

KT-309 is a fine satin gold pigment built on natural mica coated with rutile titanium dioxide, iron oxide, and tin oxide — delivering a warm, silky gold luster with genuine depth and transparency. The sub-15μm particle distribution makes it well-suited for fine printing applications and cosmetic formulations where smooth finish and consistent color response matter. For formulators sourcing an iriodin 309 equivalent, KT-309 is a direct performance match produced under ISO 9001-certified manufacturing conditions.
