Urethane doming can be applied to the surface of nearly any label substrate to create a clear, semi flexible, 3D domed label with excellent clarity and gloss. Interesting visual effects can be created on domed labels by incorporating::
- Attractive background materials:
- Reflective silver or gold backgrounds
- Brushed, holographic, or otherwise patterned backgrounds
Special inks printed in combination with attractive backgrounds:
- Translucent inks allowing the substrate (e.g., holographic) to show through
- Metallic inks that “glitter”
- Backlighting through translucent label and inks.
- Unusual die-cut shapes
- Embossed features beneath the dome.
Domed labels have excellent durability indoors and out.
URETHANE DOME PHYSICAL PROPERTIES
Clear, semi flexible, excellent clarity and gloss.
Accelerated Aging, RS-4 Sunlighter with Water Spray: After 500 hours exposure in an ultra-violet light and water spray apparatus, (estimated 3-5 years outdoor weathering) specimens show no significant surface deterioration, increase in hardness, shrinkage or noticeable color or gloss change.
Outdoor Weathering: Samples show no appreciable discoloration or loss of gloss after 5 years outside. Samples will tolerate temperatures between -45º F and 170º F.
Oven Aging: Specimens show no surface deterioration, shrinkage or increase in hardness after seven days in a hot air circulation oven at 170º F.
Humidity: Specimens show no color or gloss change or objectionable shrinkage after seven days in a humidity cabinet with a condensing atmosphere at 100º F., 100% R.H..
Salt Spray: Specimens show no change or promotion of corrosion to the surface which they are mounted after 22 hrs. exposure to a salt spray test.
Abrasion and Impact Resistance: Samples resist abrasion and impact down to -20º F.. Forced indentations recover completely due to resilient nature of the polyurethane polymer.
Cleanability: Samples clean easily without marring using a detergent solution, aliphatic hydrocarbon or denatured alcohol.
Solvent Resistance: Samples show no discoloration after being immersed in unleaded gasoline ten times for ten seconds with a drying time of twenty seconds between immersions.
Chemical Resistance: Samples show no significant color change or swelling after five minutes of exposure to the following chemical solutions: 5% KOH, 5% NaCl, 5% KCl 2, 20% H2SO4, 20% HCI.
