SPARKLE SILVET® 960-30-E1 Aluminum Pigment

PRODUCT DESCRIPTION

SPARKLE SILVET 960-30-E1 is a fine particle size, bright, SPARKLE SILVER® aluminum pigment produced in pellet form to reduce the potential for generating airborne particles and to improve ease of handling. The pellets are composed of 70% aluminum pigment carried in 30% polyolefin and are produced by a low shear process for easy dispersion. The pigment flake has a cornflake geometry. The particle size distribution range is controlled to produce clean chromatic effects when used with transparent pigments and dyes. This grade will produce bright metallic effects with small grain aesthetics when used alone or with other pigments.

-Fine particle size, Sparkle Silver® flake grade

-Aluminum pigment granules

-Non-leafing


PRODUCT APPLICATION

SPARKLE SILVET E1 grades are easy to disperse and are compatible with a variety of polymers, particularly polyolefins. They are typically used to make concentrates or compounds for use in final processing by injection molding, extrusion, blow molding or blown film processes. In some cases, SPARKLE SILVET E1 can be used directly in end-use processing but care must be taken to ensure complete dispersion is achieved. Their pellet or granular form make them easy to handle and incorporate.

Additionally, SPARKLE SILVET E1 grades can be employed in co-extruded powder coating applications.

INCORPORATION GUIDELINES

Plastic Application – It is normally sufficient to tumble blend the pellets with the base resin and any additional colorants or additives before processing. Incorporation techniques should not subject the flakes to high shear forces.

Co-Extruded Powder Application – When using SPARKLE SILVET products for manufacturing powder coatings, care must be taken to maintain the aesthetics of the flake and to allow for safe incorporation. The blending of the SPARKLE SILVET with the powder coating resins should be carried out in a low intensity mixer. If this cannot be accomplished, the SPARKLE SILVET pellets should be added at the very end of a high intensity mixer cycle. The objective of mixing is only to distribute the SPARKLE SILVET throughout the batch and not to reduce the pellets to fine particles. When discharging the batch from the mixer to the extruder, the vessels should be bonded to the same electrical potential to prevent static electricity build up. Single or twin-screw extruders can then be used to provide proper dispersion of the SPARKLE SILVET into the powder coating resin. The metallic blend should be extruded below the curing temperature of the resin and then micronized to the proper size. Excessive shear at any point in this process can cause flakes to become folded or broken, thus creating a large number of smaller flakes. This will result in a reduced reflectivity of the flakes and a graying in color.


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.
