SILVEX® 420-15-DOA


-Very Coarse, particle size aluminium flake pigment

-Low Dusting, plasticizer dispersion


SX420-15-DOA is a very coarse grade of aluminium flake pigment, developed to provide “glitter” effects in mass pigmented thermoplastics. The product is supplied as a non-dusting soft granule or paste. The high concentration of metal flake in di-octyl adipate (DOA) carrier ensures both maximum formulating flexibility and good polymer compatibility. This grade is recommended for PVC plastisols, masterbatches, including liquid masterbatches and for the mass pigmentation of PVC and styrenic thermoplastics. It may also be suitable for other thermoplastics, but compatibility tests are recommended.

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. 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.
