SBC AQ 20181 G1X is a coarse particle size, “cornflake” type aluminium flake pigment paste, passivated to resist aqueous attack. It is controlled for particle size distribution, ensuring a bright, white face tone with exceptionally dark flop effect and a high degree of sparkle. This grade is intended for water-based industrial paints.

Though satisfactory results may be obtained by careful addition of the product to the liquid vehicle, the recommended method of incorporation is to briefly soak the product in 1-2 times its own weight of water or co-solvent. Dispersion is achieved by low energy stirring, using 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.
