INCORPORATION GUIDELINES

STARBRITE products should be mixed thoroughly before incorporation to assure a homogenous mix of the pigment flakes throughout the dispersion. As with all aluminum pigments, excessive shear should not be used.


SAFETY AND HANDLING

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.
