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. Proell KG will be at Fespa to show his news products as Norilux DC.

Norilux® DC is 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 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 UVIntegrator, 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 is a halogen-free two-component ink system for IMD/FIM technology. 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 can be printed on NORIPHAN® HTR N and vice versa.

NORIPHAN® XMR shows high electrical resistance in capacitive fields. The black color shades are excellent suited for touch panel applications. The highly resistant screen printing ink can be used for conventional printing applications as well. NORIPHAN® XMR shows excellent adhesion on PC films, PC blend films, pre-treated PET films and corona treated PE and PP films. Even on various scratch resistant surfaces or hard coat lacquers and TPU materials a good ink adhesion can be achieved. Pre-tests are mandatory for these substrates. 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. NoriCard LSI shows excellent laminating properties with uncoated PVC overlay films at a temperature of 140 °C (285 °F) and provides good peel strength values. 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. NoriCure® CCI LED shows excellent laminating properties and good peel strength with PVC overlay films at temperatures greater than 140 °C (284 °F). Various color shades, metallic and effect colors are available from stock.

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. The environmentally compatible and user-friendly ink system shows good printing properties and a high gloss finish. 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). Printed films are excellent deep-drawable by vacuum or high pressure forming. The matt lacquer can be used as well for matting high gloss films made of PC, pre-treated PET and rigid PVC. The screen printed deep matt lacquer surface has a soft grip and shows good scratch and chemical resistances.
