PURPOSE: To obtain an electrically conductive paint which prevents bending resistance from being increased and has good hardness, by using a specified isocyanate source compd. and a polyester polyol as binders and using scaly carbon powder and granular carbon powder as electrically conductive materials.
CONSTITUTION: Electrically conductive paint contains a binder component consisting of 1W5pts.wt. isocyanate source compd. composed of a trimethylolpropane adduct of hexamethylene diisocyanate blocked with imidazole and 100pts.wt. polyester polyol and an electrically conductive component consisting of 30W60pts.wt. scaly carbon powder and 10W40pts.wt. granular carbon powder. A coating film obtd. from the paint can inhibit the increase of bending resistance to 10 times or lower the initial value and has good characteristics such as a pencil hardness of 2 or above. Thus, the paint can be used for printed wiring boards, resistors, electrodes, etc., of input apparatuses for OA equipment.
