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. Between the product news will be 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 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® XWR is a halogen-free two-component ink system for IMD/FIM technology. NORIPHAN® XWR is formable, shows extremely high wash-out resistance and outstanding cohesion in compound. The mild screen ink can be used as decorating ink or wash-out protective layer on PC films and PET films. NORIPHAN® XWR can be printed on NORIPHAN® HTR N and N2K and vice versa. Picture 2: Smart Climate Control Panel Display, PC hard coat film is second surface printed with NORIPHAN® XWR.

NoriCure® CCI is a new UV-curing and laminable screen printing ink developed for the manufacture of plastic cards. The ink is suitable for printing on PVC and PETG core films. NoriCure® CCI 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.

Two-component pad printing ink developed for printing on glass and metals. After stoving, the printed ink film achieves outstanding resistance to chemicals and abrasion. Tampo-Jet GMI shows good printing properties and can be used for decorating perfume flacons and stainless steel products. Matt Lacquer ATM WB 6 is an amended water-based, 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.
