Primary Features & Substrates

Features

• Formulated for use in flexible applications
• Excellent resistance to edge chipping on styrene, foamboard and fluted polypropylene materials when used with a knife or router cutter.
• Long term exterior performance with proven resistance to the effects of UV degradation and color fade.
• High impact, high intensity colors with extended color gamut
• Consistent color density values
• Adhesion on a variety of flexible and rigid substrates

Substrates

• Reinforced vinyl banner and pressure sensitive vinyl.
• Styrene
• fluted polypropylene
• Foamboard
• Polycarbonate

Adhesion should always be tested as adhesion does depend upon curing conditions, age and manufacturer of substrate. Adhesion may be improved when the substrate is cleaned with a suitable solvent such as isopropanol.

Ink Handling

All personnel mixing and handling these products must wear gloves and eye protection. Clean up all spills immediately. If ink does come in contact with skin, wipe ink off with a clean, dry cloth (do not use solvent or flush solution). Wash the affected area with soap and water. Consult the Nazdar® 7300 Series Material Safety Data Sheet for further instructions and warnings.

Ink Changeover

Thoroughly clean your current ink system and jet assemblies with LWU7001FF UV Flush Solution. Avoid contact with skin. Wear protective safety glasses and appropriate gloves when handling flush solution. Consult MSDS for proper procedures for using Flush solution. Check, clean and replace, where necessary, mesh filters at the base of primary ink tanks. Complete conversions procedures available upon request.

When UV digital equipment is not in use for extended periods of time the ink should be flushed from the printheads to avoid unwanted curing from stray light sources that can cause permanent printhead damage.

Curing Parameters

Nazdar® 7300 Series Inks are formulated to cure when exposed to a focused, medium pressure mercury vapor lamp providing 200 - 250 mJ/cm² and 450 mW/cm². (EIT Uvicure Plus radiometer, measuring the UVA spectrum)

Clean Up

For clean-up of ink spills and equipment use LWU7001FF UV Maintenance Solution. Avoid contact with skin. Wear approved safety glasses and appropriate gloves when using Maintenance Solution. Consult the MSDS for further safety precautions.

Storage/Shelf Life

Store ink and flush solutions at 18° - 27° C (65° - 80° F). Ink and flush solutions should always be kept away from heat, sparks, and flames. If stored at a different temperature, the ink should be allowed to reach room temperature before calibration or printing. The shelf life of this product is 12 months from the date of manufacture when stored under prescribed conditions.

Ink Performance

Outdoor Durability

When Nazdar® 7300 Series Inks are used with the proper color management, color variance will be minimal over a period of 24 months vertical outdoor exposure. Outdoor durability is based on actual outdoor weather testing in the central US.

To ensure Nazdar® 7300 Series Ink density and hue values do not change during outdoor exposure, it is important to use proven substrates (flexible vinyls and pressure sensitive vinyls) that do not "yellow" or vary from their original white cast when exposed outdoors.
