UV INK & COATINGS
Coatings mentioned in this brochure represent a selection of our product programme UV Gloss coatings. Many special coatings, for example UV based primers or coatings for other printing processes such as web offset, gravure or digital printing, are available on demand.
UV-curable coating technology provides benefits in terms of good performance, environmental compatibility and processing efficiency.
Liquid forms of UV-curing systems are solvent-free, require low energy for curing, and are adaptable to most conventional coating methods. Employing either radical or cationic curing mechanisms, the cross linking of these coatings is initiated by means of UV light.
UV-curable coating formulations are based on acrylated oligomers (mainly acrylic esters of polyesters, polyethers, polyurethanes and epoxy resins).
NARROW WEB UV FLEXO INKS
Is suitable for labels and certain flexible packaging applications where specific demand for low migration is required.
It can be used in all narrow web flexographic print units provided the ink is cured (exposed to UV light).This Narrow Web UV ink can also be used with reversed angle doctor blades as well as chambered doctor blades.
- Self adhesive labels(coated & uncoated papers, PE, top coated PE & PP, cast coated papers and PVC)
- Wrap around labels
- In-mould labels(BOPP)
- Unsupported film applications
- Sleeves

Storage and shelf life
- UV Curable inks should be stored and handled in packing container
- Ahead space should be present in any storage container to support the oxygen requirements of the inhibitor
- The material should be stored in dark and at temperature not exceeding 25°C.
- Exposure to direct sun light , freezing and heat should be avoided.
- Shelf life of the material is six months from the date of manufacturing.
Safety and handling
Materials in these inks can cause eye and skin irritation, and have potential to cause skin sensitization in susceptible individuals .Proper hygiene practices should be utilized.
