-Non-leafing Corn Flake aluminum flake pigment granule

-Coarse particle size

-Inhibited and surface treated for waterbased systems

-Supplied as a solvent-free soft granule


SILBERCOTE AQ-G 3130 is a coarse particle size corn flake pigment, encapsulated for use in waterborne paint systems. It is supplied in the form of a soft granule, carried in a combination of surfactants and dispersants. It has excellent compatibility with solvents typically used in waterborne paint systems, including glycols, alcohols, acetates and water, and provides greater hiding power then the equivalent paste grade. Gassing performance is equivalent or better compared to paste form.

Dispersion is easily achieved by direct incorporation of the granule into the resin system, using low energy stirring with a slow speed blade capable of moving the whole mass. This premix is then slowly added to the agitated bulk of the binder. If it is necessary to use high shear to dissolve or disperse any component of the binder, this should be done before introducing the premix. The final pH should be as close to neutral as possible. High shear should be avoided as it bends and breaks the flakes, reducing both brightness and gassing resistance. As the water stability of this grade may be system dependent, trials are recommended to verify the required level of performance.


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.
