Proell KG Showcases New Developments at FESPA 2015

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, which the compay will showcase during FESPA 2015.

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.
 
Proell offers a wide range of IMD/FIM screen printing inks (NORIPHAN HTR N and N2K) and adhesion promoters (NoriPress SMK and AquaPress ME) for film insert molding.

The latest development is NORIPHAN XWR, a halogen-free ink system for IMD/FIM technology. NORIPHAN XWR shows extremely high wash-out resistance and outstanding cohesion in compound. The mild two-component screen ink can be used as decorating ink or wash-out protection layer on PC films and PET films. NORIPHAN XWR can be printed on NORIPHAN HTR N and N2K and vice versa.
 
NoriCard CCI is a new UV-curing and laminate able screen printing ink developed for the manufacturing of plastic cards. The ink is suitable for printing on PVC and PETG core films.
NoriCard 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.
 
NoriGlass TPI is a glossy silicone and halogen free 2-component glass screen printing ink. The ink has been developed for the decoration of glass, particularly for symbols of touch switches and for backlit displays, e.g. smart phone and tablet displays. This organic screen printing ink provides very high resistance to aqueous household cleaners, hand and machine dishwashing detergents as well as to chemicals and solvents like aliphatic and aromatic hydrocarbons, alcohols, greases and oils.
Besides its excellent resistances, the ink system shows low electrical conductivity, even the black color shades. Highly opaque deep black or brilliant white color shades are available from stock.

NoriCure UV-L 3 is a UV-curing screen printing lacquer showing excellent scratch and abrasion resistance. The cured surface of the lacquer resists even strong wipes with steel wool.
The high glossy UV-lacquer is designed for printing on PC films, coated PET films (e.g. Autotype Autoflex EPG 180, Autotex V200), and various rigid PVC films and for overprinting of printed products.

The lacquer is used to overprint and protect displays, lenses and panels. The cured lacquer shows excellent resistances to chemicals and cleaning agents. Besides the high glossy NoriCure UV-L3, matt (NoriCure UV-L 3-001) and textured (NoriCure UV-L 3-002) as well as UV-stabilized (NoriCure UV-L 3-003) versions are available. For decorative applications, lacquer versions containing pearlescent and chameleon pigments are obtainable as well.
