01AQUA PASTE® 2169-C43

AQUA PASTE® 2169-C43 Inhibited Aluminum Pigment

PRODUCT DESCRIPTION

AQUA PASTE 2169-C43 aluminum pigment paste has been developed to provide enhanced resistance to gassing in water-based coatings. As it contains hydrocarbon solvents, a bridging solvent is required for water compatibility. Gassing resistance is generally superior to that of AQUAVEX® S and AQUAVEX P products.

-Non-leafing

-Fine particle size, cornflake

-Passivated for water-based systems


PRODUCT APPLICATION

AQUA PASTE 2169-C43 is intended for aqueous automotive and industrial coatings requiring bright face color combined with good flop and hiding power.
– OEM
– Refinish

INCORPORATION GUIDELINES

The paste should be soaked for one or two hours in about its own weight of a bridging solvent, such as butyl diglycol. Dispersion is then achieved by low energy stirring, using a slow speed blade capable of moving the whole mass. Further solvent, water 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. As the water stability can be system dependent, small-scale trials should be carried out to verify the required level of performance.


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. 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.
