Proell KG to Showcase Ink, Coating Portfolio at Fespa 2017

Proell KG’s core business lies in the development of custom-made chemical products for coating/decorating plastics and other materials, as well as innovative ink systems for IMD/FIM technology, and screen and pad printing inks.
 
Among the product that will be highlighted are Norilux DC, a formable, abrasion resistant Dual-Cure screen printing lacquer. Norilux DC can be used as protective lacquer or hard coat on PC, PMMA, ABS and PP films.

Norilux DC is ideally suited for first surface coating/protection of products manufactured in IMD/FIM technology. The glossy version of the Dual-Cure lacquer can be printed on textured film surfaces to produce abrasion resistant and transparent display windows.

The matt version of Norilux DC can be printed on uncured transparent hard coat films such as Makrofol HF 278 or 312 to create matt and high gloss effects in one item. Besides the high glossy Norilux DC lacquer, various satin gloss, textured and matt grades as well as pigmented and UV-stabilized versions are available.

Tactile surface structures e.g. brush effects and 3D patterns can be printed with the highly resistant lacquer. The Dual-Cure screen printing lacquer can be used for overprinting silicone-free UV, solvent and water-based screen printing inks as well.

Norilux DC dries by evaporation of the solvents in jet dryers. 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 e.g. by high pressure forming or thermo forming. 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 cured lacquer layer shows excellent resistances to abrasion, chemicals and cleaning agents and passes various creme tests of the automobile industry. In automotive interior, center stacks, touch panels and decorative trims are first surface protected with Norilux DC. Even mobile phone covers and sanitary panels are overprinted with the highly resistant lacquer. Second surface decoration is printed with the IMD/FIM ink system NORIPHAN HTR N.
 
NORIPHAN XMR screen printing ink is designed for IMD/FIM technology. It is a halogen-free two-component ink system. NORIPHAN XMR is formable, shows extremely high wash-out resistance and outstanding cohesion in compound. The mild screen printing ink can be used as decorating ink or wash-out protective layer on PC films and PET films.
 
NORIPHAN XMR shows high electrical resistance in capacitive fields. The black color shades are excellent suited for touch panel applications. In case of decorating 3D parts, NORIPHAN XMR can be processed by pad printing as well.
 
NoriCard LSI is a solvent-based screen printing ink for printing on PVC core films used in card manufacturing. It shows excellent laminating properties with uncoated PVC overlay films. The NoriCard LSI metallic ink system includes various gold and silver colors of different pigment particle sizes (from fine, middle-coarse and coarse). The user-friendly formulated ink is free of aromatic solvents and cxclohexanone.
 
NoriCure CCI LED is a new UV-LED curing screen printing ink developed for the manufacture of plastic cards. The ink is suitable for printing on PVC and PETG core films and subsequent lamination process.
 
Aqua-Jet WT is a water-based screen printing ink for printing on wood and plastics (only after pretests) for indoor application, especially for wooden toys. Aqua-Jet® WT is free of aromatic solvents, cyclohexanone, NMP, PVC, phthalates and organotin compounds.
 
Matt Lacquer ATM WB 6 is an amended water-based, UV-stabilized and formable matt lacquer system for overprinting polycarbonate film instrument gauges (speedometer panels).
