CARBON BLACK ITS INFLUENCE & SELECTION CRITERIA

Carbon Black does not add gloss, it detracts from gloss. Therefore it is important to use the carbon black that detracts as little as possible. For Eg. High structure grades detract more from the gloss of a finished product than a low structure grades. Masstone referes to the degree of jetness that carbon black imparts to a product.
