Pröell GmbH Sets Plans for Fakuma 2024

Proell will be showcasing a range of products at Fakuma 2024. Its core business lies in the development of custom-made chemical products for coating/decorating plastics, metals, glass and other materials, as well as innovative ink systems and protective lacquers for IMD/FIM technology, and screen and pad printing inks.

Product News:
• NORIPHAN HTR N 990/011 NC – non-conductive black for IMD/FIM technology

NORIPHAN HTR N is an established, formable, backmoldable and solvent-based one-component screen printing ink for the film insert molding technology.
Due to the development of the new deep black opaque color shade NORIPHAN HTR N 990/011 NC, a carbon black-free, non-conductive black is available for printed electronic applications now. The color shade has a high optical density, an electrical resistance in the giga ohm range and is radar transmissible.

The color shade can be used for decorative prints but is mainly used for plane multi-layer pre-printing (under-layering) for metallic and polymer conductive pastes. Carbon-based pigments, so called carbon blacks, normally used for black color shades, are electrically conductive and can interfere with the functional structures. NORIPHAN HTR N 990/011 NC meets the increased requirements regarding thermal resistance and the demanding hydrolysis test in the automotive industry.

• NORIPHAN HTR N 959 IR transparent black screenprinting ink for IMD/FIM technology

With the development of the IR transparent NORIPHAN HTR N 959, a carbon black free, non-conductive black color shade is available for functional touch panel applications. The color shade has a black appearance in incident light. Under transmitted light the color shades appear transparent and is ideally suited for IR & lidar transmitting areas in display and touch panel applications.

• NORIPHAN HTR N 945/546 – UV stabilized white

NORIPHAN HTR N 945/546 is a special adjusted UV stabilized white color shade, which can be used for BEV front modules. Front modules for electric cars will be decorative, multi-colored, and functional.

The screenprinted ink layers are located in between a film and coating compound.
Thereby, the IMD/FIM screen printing inks are protected by the transparent films and hard coat layers. Nevertheless, the weathering stress on a whitely screen printed ink layer is very high, so that a special pigmentation is necessary to adjust the color shade stable.

• NORIPHAN HTR N 093/444 – mild formulated one-component lacquer

The transparent and with mild solvents formulated screen printing lacquer is part of the one-component NORIPHAN HTR N IMD/FIM ink range. The lacquer is used to print on solvent-sensitive inks (e.g. Mirror Ink M3 N) and sensitive PC substrates, as well as to overprint and protect conductive silver pastes.

• NORIPHAN N2K non-conductive screen printing ink for IMD/FIM technology

NORIPHAN N2K is a well-established solvent-based two-component screen printing ink for IMD/FIM technology. The glossy ink system is optimized for processing thin PC films (< 175 µm). Films decorated with NORIPHAN® N2K show no curling effect.
Nowadays this IMD/FIM ink system is used especially for printed electronics applications. The deep black and opaquely formulated color shade NORIPHAN® N2K 953 is suitable for the decoration of touch panels and shows high electrical resistance in capacitive applications.

The NORIPHAN® N2K 953 color shade meets the increased requirements regarding thermal resistance and the demanding hydrolysis test in the automotive industry. NORIPHAN N2K ink system is also used for overprinting, embedding and protecting of the sensitive conductive pastes. The ink layers prevent from wash-out effects during the injection molding process. Films printed with NORIPHAN N2K are perfectly suitable for the IMD/FIM process (In-Mold-Decoration/Film Insert Molding).

• Adhesion Promoter PP L67333 – Adhesion Promoter for PP-IMD/FIM

Adhesion Promoter PP L67333 is an adhesion promoter for IMD/FIM technology (Film Insert Molding) which makes back molding of second surface screen printed polypropylene films with polypropylene injection molding material possible. Up to now, back molding of PP film laminates was possible only.

• NoriCure ORL-1
The weather resistant UV curing lacquer can be used for overprinting of solvent-based ink systems (for example, Thermo-Jet, NoriPUR) as well as for printing on PVC self-adhesive films, polycarbonate, rigid PVC and PMMA. NoriCure ORL-1 protects the overprinted ink layer from UV-radiation and is outdoor resistant.
