Abstract
The invention relates to a composition for producing magnetic or magnetizable moldings, comprising from 95.5 to 98.95% by weight of a powder made of a magnetic or magnetizable material, from 1.0 to 4% by weight of a mixture made of at least one epoxy-novolak resin, and also of at least one hardener, and comprising from 0.05 to 0.5% by weight of at least one additive, based in each case on the total weight of the composition. The mixture made of the at least one epoxy-novolak resin and of the at least one hardener comprises from 85 to 95% by weight of the epoxy-novolak resin and from 5 to 15% by weight of hardener. The hardener has been selected from (cyclo)aliphatic amines and their adducts, polyamides, Mannich bases, amidoamines, phenolic resins, imidazoles, and imidazole derivatives, dicyandiamide, and BF-monoethanolamine. The invention further relates to a process for producing the composition, and also to a process for producing a molding made of the composition.
