These pearlescent powders based on natural mica, can be used in all resins, solvent-based and water-based systems. Suitable for interior and exterior applications. They give a coloured metallic appearance although some are somewhat translucent. Selection of these pigments is based on heat & chemical resistance and the tolerance to a wide pH range. They are also lightfast so the colours do not fade. Pigment ratio should never exceed 10% of your resin mix as not to disturb the chemical balance which may affect the curing of the final project.
