technical data sheet NAZDAR Multi-Chromatic Specialty PigmentsMulti-Chromatic pigments are added to solvent-based and UV-curable screen printing ink systems and provide a metallic finish with color-travel variations depending on viewing angle. For example, one of the pigments changes color appearance from subtle turquoise through brilliant silver to metallic red hues. The pigment should be printed over a black surface to achieve the highest effect. These pigments can be combined with transparent colors to provide additional effects. |

UsesMulti-Chromatic pigments can be used with Nazdar solvent-based and UV-curable ink series. User InformationMeshMatch the screen mesh count to the particle size. When the mesh opening is too small, larger pigment particles are blocked from passing through the screen and onto the substrate, eventually blocking the ink. The standard Multi-Chromatic pigments available range in size from 5-50 microns. 230-305 tpi mesh can be used; the higher mesh count may produce more blocking of the mesh with longer print runs. Reference your mesh manufacturer's guidelines as to the mesh count, thread diameter, and mesh open area. Pigment LoadMix up to 10% pigment by weight depending on ink system, mesh count, adhesion, cure, and desired effect. When inks are to be printed over Multi-Chromatic colors, the overprinting ink(s) must be evaluated for intercoat adhesion before proceeding with the production run. To maximize intercoat adhesion over Multi-Chromatic colors, we recommend that Multi-Chromatic colors be printed as late as possible in the print sequence. Multi-Chromatic pigments can be combined with Pearlescent and Interference pigments to create numerous effects. Higher pigment loads may require higher cure levels. Test adhesion properties when determining pigment load. Mixing ClearMulti-Chromatic pigments are intended to be used with mixing clear or metallic mixing clear. |
StorageTightly closed in dry area. HandlingInhalation is the primary route of exposure and irritation with Multi-Chromatic pigments. Therefore, it is recommended that all personnel mixing and handling these products minimize the creation of dust. If pigment is inhaled, seek fresh air and consult a doctor if feeling unwell. Consult the Safety Data Sheet for further instructions and warnings. Printed MaterialSpecial Effects Color Card (CARDSPL): provides screens printed samples and visual reference of the Pearlescent pigments over white and black backgrounds. PackagingAll pigments are available in 1 pound containers. Multi-Chromatic Pigments
