<p>PURPOSE:To prepare the title paint having low temperature- and humidity-coefficients of electrical resistance, by adding powder of an insulator having specific particle size to a resistance paint composed of a thermosetting resin and carbon black. CONSTITUTION:The objective paint composition is prepared by adding (A) 1-7 parts by weight, pref. 2-7 parts of powder of an insulator (pref. SiO2 power) having an average particle diameter of 1-50mu, to (B) a resistance paint composed of (a) 7 parts of a thermosetting resin such as phenol-modified xylene resin and (b) pref. 0.5-2.0 parts of carbon black.</p> |
