Claim of US Patent No. 10,433,371

1. An electrothermic composition comprising:at least a first conductive carbon component selected from the group consisting of: conventional thermal blacks, furnace blacks, lamp blacks, channel blacks, surface-modified carbon blacks, surface functionalised carbon blacks, and heat-treated carbons;
a second resistor component which is graphite having a crystallinity of 99.9%, and wherein the graphite is heat treated at a temperature 2500° C. to 3000° C.; and
a carrier or binder;
whereby the composition has a thermal coefficient of electrical resistance (TCR) of +/?0.000110 to 0.0015 per ° C. over a temperature range of from about 200° C. to 550° C. in an airborne environment, and
wherein the ratio of the first conductive component and the second resistor component is selected between 10:1 to 1:10.
