E-2507 AR Aluminium Paste


-Non-leafing aluminium flake pigment

-High sparkle


E2507AR is a coarse particle size, non-leafing, lenticular or “Silver Dollar” aluminium flake pigment paste. In visual properties, its main characteristic is a finer appearance than its particle size would suggest. A very bright face colour is accompanied by a smooth patina and a subtle sparkle. Opacity is slightly greater than the related SS3622. E2506AR is recommended for solvent- based bicycle and automotive component finishes.

The paste should be soaked in about its own weight of solvent, ideally for one to eight hours. If using solvent alone is not feasible, the liquid coating medium can be substituted, but the dispersion time may be extended. Dispersion is best achieved by low energy stirring, using a slow speed blade capable of moving the whole mass. Further solvent or medium may be added at this stage. When a smooth consistency, free of soft aggregates has been obtained, the balance of the formulation may be slowly added. High shear should be avoided as it bends and breaks the flakes, reducing their brightness.


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.
