ⅰ. CCP-121Carbon Paste (low-resistance carbon paste with low price) 
CCP-121 is carbon paste of one-component polymer type designed for the the membrane switches and the flexible printed circuits. The resistance is low. CH-1N makes it possible to improve the performances of the printed matter as well as to save the cost.

CHARACTERISTICS 
Low resistance. 12.0 ohm/sq.cm, thickness : 14 microns 
Low price with good cost-performance:
Good adhesion to PET film.
Excellent flexibility.
One component type. Stable in long storage. Good printability.
Compatible with other makers' silver paste.
