2 5 grams of bicyclohexyl solvent 16 38 grams of pelletised carbon black powder surface area u02dc 254 m 2 g and 16 38 grams of graphite particle size 8 15 microns the resulting mixture was then triple roll milled to yield a smooth homogenous ink the resulting ink had a solids content of 22 7 wt at 150 degrees celsius and a viscosity of 71 pa s at 10 rpm a solution polymer was made by adding 20 00 grams of a chlorinated polyolefin resin powder chlorine content 18 23 wt to 80 00 grams of bicyclohexyl solvent the resulting mixture was then heated to a temperature of 60 degrees celsius until the resin had fully dissolved the resulting solution was then cooled to room temperature prior to use in the production of the various inks described below this composition was remade numerous times a 98 60 gram amount of the solution polymer described in example 4 was mixed with 13 46 grams of pelletized carbon black powder surface area u02dc 254 m 2 g and 13 46 grams of graphite powder particle size 8 15 microns the resulting mixture was then triple roll milled to yield a smooth homogenous ink the resulting ink had a solids content of 36 4 wt at 150 degrees celsius and a viscosity of 193 pa s at 10 rpm an 85 85 gram amount of the solution polymer described in example 4 was mixed with 7 68 grams of pelletized carbon black powder surface area u02dc 254 m 2 g and 20 47 grams of graphite particle size 8 15 microns the resulting mixture was then triple roll milled to yield a smooth homogenous ink.
