WR TECHNICAL DATA SHEET
MULTI-PURPOSE BANNER APPLICATION UV INK
WR is distinct in its ability to offer non-blocking, flexibility needed for banner applications while also providing adhesion to nearly all point-of-purchase stocks. This provides screen printers with the opportunity to reduce ink inventory by stocking a single ink line. Custom colors can also be duplicated easily on various stocks.
Unlike other multipurpose inks, Ultrabond’s exceptional flexibility and adhesion stands up to the demand of the most stringent finishing requirements. Ultrabond provides a durable, non-blocking surface and has excellent outdoor durability.
PERFORMANCE PROPERTIES
• Broadcast adhesion range of any NUVS UV ink
• Flexible for sewing, grommeting and die cutting without cracking
• Allows durable face printing without re-wetting or picking
• Low tack finish to eliminate slip sheeting
• Water and abrasion resistant
• Superior opacity provides better color trapping
• N-VP Free
RECOMMENDED SUBSTRATES
Excellent adhesion to vinyl banners, electrostatic vinyl and polyethylene banner material having treatment levels of at least 40 dynes. Ultrabond also provides excellent adhesion to ABC, Acrylic, Cardstock, Expanded PVC, Print Treated Polyester, Coated/Uncoated Paper, PETG, treated HDPE, Polycarbonate, Fluted Polyolefin’s, Treated Polypropylene, Polystyrene, Tyvek, Pressure Sensative Vinyl, Unsupported Vinyl, and Low Tack Vinyl. Ultrabond has also shown good adhesion to coated metals.
To determine suitability of the product for the intended use, a pretest prior to production is advised. Our recommendations are based on present knowledge. Due to the limited life of surface treatments on polypropylene banner (Propaque) and fluted polyolefin materials (Coroplast), testing is required prior to production.
CURING: Ultrabond will cure well when printed through 355 (140 cm) plain weave polyester mesh or finer. A minimum of 125-160 mJ’s are required to cure standard WR colors and banner stocks. This optimal cure window is generally achieved with one 200 watt per inch mercury vapor lamp at belt speeds between 75-100 feet (20-30 meters) per minute. Heavier gauge stocks and dark colors, which may act as a heat sink, may require 200 mJ’s or more.
Adhesion should be a minimum of 95% from curing unit with final adhesion developing within four hours of initial polymerization. Coarser fabrics can be utilized; however, cure parameters may need to be adjusted for the increased ink film.
If a loss of gloss or adhesion due to insufficient cure is noticed, the use of 5-10% WR Mixing Clear will increase light penetration and improve cure. Additions of Thinner will not improve cure and may cause the rate of decrease
PRINTING: Mix well prior to every use. Although WR has been supplied in press ready condition, this system may be reduced up to 10% with WR Thinner for special viscosity adjustments.
Care should be taken to print the ink at the optimal temperature of 70°-90° F (21°- 27°C). Cool ink will have heavier viscosity and will not flow properly whereas excessively warm ink will be lower in viscosity resulting in poor definition and decreased opacity.
SQUEEGEE: 70 - 90 durometer polyurethane blade is recommended.
COVERAGE: 3600 to 3800 square feet per gallon for film deposit of .40 to .60 mil.
OUTDOOR USE: Extensive accelerated weathering tests have been completed on vinyl printed with Ultrabond, with an Overprint Clear. The ink withstood 1,500 hours of exposure with 4 hour cycle times of UV light and condensation at elevated temperatures with minimal color change and marginal shrinkage.
Accelerated machine weathering are reference standards and can’t precisely reproduce actual outdoor performance. Based on prior correlation of accelerated testing versus real time exposure, 1,500 hours is equated to approximately three years, 45° south Florida.
METALLICS: A superior two part system comprised of WR Metallic Mixing Clear and the proper metallic paste has been developed. The increased viscosity of MMC helps insure a good particle suspension and our new metallic technology provides unparalleled premix shelf life and stability. The recommended mixing ratios are: 12% silver paste, 28% gold paste (by weight) to achieve the standard metallic colors.
For optimum coverage and opacity, 280 - 305 (110 - 120 cm) plain weave monofilament mesh is recommended. Use WR Overprint Clear for extended weatherability and to improve the non-tarnishing properties of the product.
STORAGE: Care should be taken to store ink in tightly closed containers located in a cool (6F to 8F / 15° to 27°C), dark place. After long production runs, excess ink from the screen should be properly disposed. With suitable conditions, the ink is expected to have a shelf life of approximately 12 months from the date of manufacture.
PRECAUTIONS: Read the material safety data sheet prior to processing. It contains instructions for precautions when processing, handling and storing inks, as well as first aid. If ink comes in contact with skin, wipe ink off with a clean, dry cloth (do not use solvent). Wash and rinse the affected area with soap and water.
PROCESS PRINTING: For superior halftone reproduction, Ultrabond halftones are available in three density levels. Additional control of densities may be achieved with the use of WR Halftone Extender Base. For best results, 380 (150 cm) plain weave mesh or finer and a smooth, thin stencil coating should be utilized with four color process
printing.
