PLASTICS (Master Batch form)
Metallic pigments may be used successfully in combination with many polymeric substrates reaching high quality metallic effects. We do not recommend the direct use of metallic pigments in injection or extrusion processes. Agitators that don't minimize the ciseling of the metallic pigment and enough time for the homogenization must be used. The viscosity of the polymeric mean is also an important factor; high viscosity systems will orient the pigment in the direction of the polymer expansion, generating unsatisfactory effects. The regulation of equipment and moulds which allow uniform fluidity of the material are also important factors in obtention of the metallic effect desired, weak injection flux will result in formation of clouds in the end product.
Metallic pigments of higher granulometry present enhanced metallic effects and are less susceptible to oxidation, unlike the lower granulometry ones.
