Substrates

• Polycarbonate

Substrate recommendations are based on commonly available materials intended for the ink's specific market when the inks are processed according to this technical data. While technical information and advice on the use of this product is provided in good faith, the User bears sole responsibility for selecting the appropriate product for their end-use requirements. Reference the 'Quality Statement' at the end of this document.

User Information

Mesh

305 - 380 tpi (120 - 150 tpcm) monofilament polyester mesh for most applications.

Stencil

Use direct emulsions and capillary films which are solvent resistant.

Squeegee

70-80 durometer polyurethane squeegee.

Coverage

Estimated 2,500 - 3,500 square feet (230 - 325 square meters) per gallon depending upon ink deposit. Reference www.nazdar.com for examples of coverage calculations.

Printing

667702KI Special Mirror Silver ink is formulated to be press ready. Add only enough ink to the screen to be able to print for 5-10 minutes. Add additional ink in small increments throughout the print run to maintain screen stability. Thoroughly mix the ink prior to printing. The ink must be mixed at low shear to prevent damaging the specialized pigment.

Maintain ink temperature at 65° - 90°F (18° - 32°C) for optimum print drying performance. Lower temperatures increase the ink viscosity, impairing both flow and drying. Elevated temperatures lower the ink viscosity, reducing print definition, film thickness and opacity.

Pretest to determine optimum printing performance for a particular set of ink, substrate, screen, press, and drying variables/conditions.

Nazdar does not recommend inter-mixing of 667702KI with any other ink.

Drying / Curing Parameters

The ink may be dried at room temperature or in a 140°F (60°C) oven for at least 15 minutes (drying time depends on mesh used and other factors affecting ink film thickness). Drying at higher temperatures may affect the mirror-like appearance. The ink must be thoroughly dried for optimal properties.

Due to varying ink deposits and production equipment, it is recommended that the printer evaluate the drying time and temperature that will allow the maximum reflectance for the specific application. Good air circulation is necessary to remove the vaporized solvents.

Overprint

Overprints: The following Nazdar ink systems may be printed over a thoroughly dried 667702KI ink film: 9700, 1800, or 2400. Refer to each ink system's Technical Data Sheet for more information regarding either of these inks. Overprinting with a clear or solid color ink will provide some protection to the metallic. Due to the pigment load and nature of metallic pigments, the 667702KI may not exhibit satisfactory adhesion to the substrate and overprints may not pass cross hatch tape test. Overprinting with other ink systems may cause incompatibility which affects the mirror finish; test thoroughly.

Due to the nature of the metallic pigments used in these types of the product, the layer of mirror silver may not pass tape and cross hatch tape tests. The pigment has the tendency to split or lift off upon removal of tape or adhesives from the printed surface making the mirror layer the weakest interface. Overprinting with other ink systems may cause incompatibility which affects the mirror finish; test thoroughly.

Overprint Clears / Varnishes

Overprint Clears: the following overprint clear inks may be printed over a thoroughly dried 667702KI ink film

Cleanup

Screen Wash (Prior to Reclaim): Use IMS201 Premium Graphic Screen Wash, IMS203 Economy Graphic Screen Wash, or IMS206 Graphic Auto Screen Wash.

Press Wash (On Press): Use IMS301 Premium Graphic Press Wash.

Storage / Shelf Life

Store closed containers at temperatures between 65°-78°F (18°-25°C). Storing products outside of these recommendations may shorten their shelf life. Ink taken from the press should not be returned to the original container; store separately to avoid contaminating unused ink.

General Information

Ink Handling

All personnel mixing and handling these products must wear gloves and eye protection. Clean up spills immediately. If ink does come in contact with skin, wipe ink off with a clean, dry, absorbent cloth (do not use solvent or thinner). Wash the affected area with soap and water. Consult the applicable Safety Data Sheet (SDS / MSDS) for further instructions and warnings.

For assistance on a wide range of important regulatory issues, consult the following Regulatory Compliance Department link at http://www.nazdar.com or contact Nazdar Ink Technologies - World Headquarters (see contact listing at the end of this document).
