Carbon black dispersed phenolic resin composition, epoxy resin composition and method for producing the same

摘要

PROBLEM TO BE SOLVED: To provide an epoxy resin composition that prevents the agglomeration of carbon black.;SOLUTION: A carbon black-dispersed phenolic resin has carbon black dispersed in a phenolic resin. When measured by dynamic light scattering, the carbon black has an average particle size of 80 nm or more and 400 nm or less, and the particle size distribution of carbon black has one peak.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2019,JPO&INPIT
