SPARKLE SILVET® 797-20-J Aluminum Pigment

PRODUCT DESCRIPTION

SPARKLE SILVET 797-20-J is a medium particle size, bright aluminum pigment produced in granule form to reduce the potential for generating airborne particles and to improve ease of handling. The pellets are composed of 80% aluminum pigment carried in a 20% aldehyde resin binder 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 strong metallic effects with medium grain aesthetics when used alone or with other pigments. SPARKLE SILVET 797-20-J is suitable for use in powder coatings applications.

-Non-leafing

-Aluminum pigment granules

INCORPORATION GUIDELINES

Coatings Application – Pre-weigh the required amount of granules and cover with preferred solvent. Leave for approximately ten minutes to allow the solvent to penetrate the binder matrix. With gentle stirring, slowly add the resin system, and finally, add solvent until desired viscosity is achieved. It is advisable to pre-mix any resins, micro waxes or additives into a resin system prior to mixing with the aluminum dispersion.

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.
