Product News:
1. NORIPHAN® HTR N 990/011 NC - non-conductive black for IMD/FIM technology
NORIPHAN HTR N is a formable, backmoldable and solvent-based one-component screen printing ink for film insert molding technology.
Due to the development of the deep black opaque shade NORIPHAN® HTR N 990/011 NC, a carbon black-free, non-conductive black is available for printed electronics.
The color shade has a high optical density, an electrical resistance in the giga ohm range and is radar transmissible.
The black can be used for decorative prints but is mainly used for plane multi-layer printing of conductive pastes. Carbon-based pigments, so called carbon blacks, normally used for black colors, 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 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.
