ET2461 provides less opacity and a brighter, more sparkling appearance than the related ST790-30-E1. It is recommended for use at 1.5-2.0% w/w on polymer to provide a subtle sparkle effect in coloured metallic formulations. When used alone for silver metallic effects, a loading of up to 3.5% is required for colour saturation and opacity. ET2461 is suitable for moulding articles coming into indirect contact with food. Like all flake pigments, optimum colour and brightness will be obtained by incorporating this grade under conditions of good mixing, but low shear. The granular delivery form allows tumble blending or easy metering into polymer, prior to processing.
