ET-2018 Aluminium Pigment


– Specially formulated for creating pearlescent effects

-Exceptionally bright aluminium flake pigment

-Low dusting, Dry granular form

-Wide polymer compatibility


ET2018 presents a very bright, but fine particle size grade of aluminum flake, in an easily handled, low dusting, granular form. The carrier resin has been chosen to provide compatibility with a wide range of thermoplastics, including styrenics, polyolefins, polyamides, polyesters and acetal polymers. It may also be suitable for certain grades of EVA, polycarbonate and PVC, but compatibility tests are recommended.

ET2018 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 ET2018 as low as 0.01-0.1%. Good dispersion of such low concentrations is achieved by limiting the metal concentration of ET2018 to 40%. As the whiteness of pearl effects using this grade is limited by the color of the aluminum itself, ET2018 is likely to find most use in simulating the deeper pearlescent shades. Such formulations are extremely cost effective, due to the very low ET2018 concentrations required. This grade is also a good choice for packaging films, where it provides a brighter silver, with better dispersibility, though lower opacity, than Silvet® 210-30-E1. Like all flake pigments, optimum color and brightness will be obtained by incorporating ET2018 under conditions of good mixing, but low shear.


Aluminum pigment should be stored in the original shipping container and kept tightly sealed. Store containers in a cool, dry, well-ventilated, and properly rated area. Avoid any conditions that will suspend or float the particles in the air, creating a dust cloud. Avoid all possible sources of ignition. For additional information, please refer to the Safety Data Sheet (SDS) for this product, available from Silberline upon request. An SDS is supplied with all samples of this grade.
