The exceptional brightness of this grade makes it particularly suited to the simulation of medium-fine automotive paint finishes. For this application, a concentration of 2-4% on polymer is suggested.
For most applications it will be sufficient to tumble blend ET2025 with polymer granules prior to extrusion or moulding. Only for very low concentrations or a particularly high degree of dispersion is it sometimes necessary to prepare an intermediate masterbatch. High shear at any stage of incorporation should be avoided as it bends and breaks the aluminum flakes, causing darkening and loss of metallic whiteness.
