ET2271 has been formulated to provide colored pearlescent effects when combined with organic and inorganic pigments and dyestuffs. To create such an appearance, light reflection is required from depth within the polymer. This is achieved by concentrations of ET2271 as low as 0.02 – 0.2% by weight. As the whiteness of pearl effects using this grade is limited by the color of the aluminum itself, ET2271 is likely to find most use in simulating the deeper pearlescent shades. Such formulations are extremely cost effective due to the very low concentrations required. This grade provides a coarser appearance than the related ET2018.
Like all flake pigments, optimum color and brightness will be obtained by incorporating ET2271 under conditions of good mixing, but low shear. For applications such as sheet and film, requiring the highest degree of dispersion, it may be necessary to prepare an intermediate masterbatch.
