ETERNABRITE® E-651
ETERNABRITE® E-651 Aluminium Paste
-Leafing aluminium flake pigment
-Very fine particle size
-Exceptional reflectivity
EternaBrite E651 is a very fine particle size, leafing type aluminium flake pigment paste. It has greater covering power than EternaBrite E301 and more polish than EternaBrite E601. This grade is recommended for solvent based surface coatings in which a highly reflective, lustrous metallic effect is required.

The paste should be soaked in about its own weight of solvent, ideally for one to eight hours. Strong solvents, i.e. those that are highly polar, are best avoided as they can reduce the leafing effect. 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 and leafing effect.
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.
