Silberline Start




-Coarse, sparkling, aluminium flake pigment

-Low-dusting, plasticiser dispersion, granule form

-Compatible with polyolefins and other polymers


SX764-20-C provides a coarse particle size aluminium flake pigment in a low-dusting delivery form. The metal content is 80%, allowing maximum formulating flexibility, whilst retaining excellent dispersibility. The carrier is mineral oil, which has good compatibility with polypropylene and polyethylene. It may also be suitable for mass pigmentation of other polymers, but compatibility tests are recommended. This grade provides a high degree of sparkle, but low hiding (opacity) in coloured metallic formulations. A concentration of about 1% is generally sufficient in such applications. When used alone, concentrations up to 4% or more may be required for colour saturation.

For most applications it will be sufficient to tumble blend the product with polymer granules and other colorants prior to extrusion or moulding. High shear at any stage of incorporation should be avoided as it bends and breaks the aluminium flakes, causing darkening and loss of metallic brightness.


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.
