SILBERCOTEĀ® PC 3331X Aluminum Pigment


SILBERCOTE PC 3331X is an inorganically surface treated cornflake type aluminum pigment. This grade is supplied as a dry powder to offer greater application versatility. To reduce environmental contamination and the explosion risk of dry aluminum flakes, it is packaged in bags permeable to air but not the metal. SILBERCOTE PC 3331X provides a bright face color and a high sparkle appearance.

-Non-leafing aluminum flake pigment

-Dry powder form

-Dust containment packaging


SILBERCOTE PC X can be formulated into post-blend and bonded metallic powder coatings. The inorganic surface treatment on the flake imparts improved chemical and environmental resistance properties in the final coating.

Specific Gravity



For powder coatings, the packaging should be cut open and the pigment gently combined at up to 5% loading with the powder coating to provide a ready-to-spray composition. For liquid coatings, the bag may be cut open and the contents allowed to discharge gently onto the surface of the solvent. If using solvent alone is not feasible, the medium can be substituted, but dispersion time may be extended. Dispersion is best achieved by low energy stirring, using a blade capable of moving the whole mass. Further solvent or medium may be added at this stage. When a smooth consistency, free of aggregates has been obtained, the remainder of the formulation can be slowly added. High shear should be avoided as it causes flake damage, thereby reducing brightness. Gassing resistance in water-based media will also be reduced.


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.
