Product News:

1. Norihan 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.

The Noriphan HTR N 990/011 NC color shade has been formulated and optimized regarding the interlayer adhesion and shows good adhesion in compound values in the final film/ink/injection material composition.

2. Noriphan HTR N 959 IR transparent black screen printing 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.

3. 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 screen printed 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.

With the Noriphan HTR N 945/546 - UV stabilized white, an optimized, nearly discoloration free, color shade is now available for the second surface application in front modules.

4. 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.
