Norilux® DC - dual-cure lacquer
Norilux® DC is a high glossy, formable, abrasion resistant dual-cure screen printing lacquer. Norilux® DC can be used as protection lacquer or hard coat on PC and PMMA films being not resistant to abrasion. Norilux® DC is ideally suited for first surface coating of products manufactured in IMD/FIM technology.
Processing of the dual-cure lacquer requires printing conditions without UV light.
The cured lacquer layer shows excellent resistances to abrasion, chemicals and cleaning agents. The dual-cure screen printing lacquer can be used for overprinting silicone free UV, solvent and water-based screen printing inks (pre-tests required). Norilux® DC dries by evaporation of the solvents in jet dryers.
The printed films are formable, e.g. by high pressure forming or thermo forming. Before further processing of the printed films, it is necessary to remove nearly all solvent residues from the layer of lacquer and substrate. Well ventilated box ovens can be used.
Films decorated with Norilux® DC can be 3D formed after box oven drying. Afterwards, the formed films must be UV cured. Depending on the thickness of the lacquer layer, UV doses of 1200-2000 mJ/cm2 are necessary (Kühnast UV-Integrator, UV 250 to 410 nm, max. 365 nm). The higher the UV dose, the better the abrasion and scratch resistance of the lacquer surface.
A matt version is available as well.
