Abstract
A method of producing coated carbon black pellets is disclosed and includes contacting carbon black pellets with a coating agent to at least partially coat the individual carbon black pellets with the coating agent. The amount of coating agent applied to the carbon black pellets is preferably from about 1% or less by weight to about 25% by weight based on the total weight of the coated carbon black pellets. Coated carbon black pellets produced by the method are also provided and exhibit excellent attrition resistance, excellent dispersibility in various elastomeric, polymeric, and other compositions, are substantially dust-free, and are free-flowing. Additionally, such coated carbon black pellets can confer beneficial processing properties on elastomeric compositions formed from the pellets, such as improved viscosity and resistance to mold fouling.
