-Exceptionally bright, polished, lenticular aluminium flake pigment

-Low dusting, Dry granular form

-Lustrous metallic effect similar to brushed steel or anodized aluminium


STU 0020-30-E1 provides an exceptionally bright, medium particle size, aluminium flake pigment in an easily handled, low dusting, meterable delivery form. The high metal content has been chosen to maximise formulation flexibility whilst ensuring good dispersibility in a wide range of thermoplastics.

When incorporated into polymers in a silver masstone, STU 0020-30-E1 can achieve a lustrous, solid metallic colour, similar to brushed steel or anodised aluminium, that a standard aluminium pigment is not able to achieve. STU 0020-30-E1 can be combined with transparent pigments and dyes to produce extraordinarily clean, polished metallic colours. It can also be incorporated into polymers at a very low addition level (typically 0.1 – 0.3%) to produce exceptional metalescent (“pearlescent-like”) effects.

This grade is suitable for styrenics, polyolefins, polyamides, polyesters and acetal polymers. It may also be suitable for certain grades of EVA, polycarbonate and PVC, but compatibility tests are recommended. Optimum colour and brightness will be obtained by incorporating this grade under conditions of good mixing, but low shear. The granular delivery form allows tumble blending or easy metering into polymer, prior to processing.


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.
