The surface characteristics of a furnace carbon black having a nitrogen surface area greater than 140 m2/g, are modified by treating the black with an organic adsorbate (eg. an n-alkane, n-alkane amine, n-alkane halide or n-alkane alcohol) having a molecular structure including a linear chain having at least four carbon atoms at a loading ranging from 1 to 2 percent by weight, whereby carbon black pores can be filled to effectively block adverse moisture absorption. |
