    Abstract: 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 BF3-monoethanolamine. It also involves a process for producing said composition and a molding made of said composition.

    Abstract translation: 一种用于生产磁性或可磁化模制品的组合物,其包含95.5至98.95重量%的由磁性或可磁化材料制成的粉末,1.0至4重量%的由至少一种环氧酚醛清漆树脂制成的混合物,以及 的至少一种硬化剂,并且包含0.05至0.5重量%的至少一种添加剂,基于每种情况,基于组合物的总重量。 由至少一种环氧酚醛清漆树脂和至少一种固化剂制成的混合物包含85-95重量%的环氧酚醛树脂和5-15重量%的硬化剂。 固化剂选自(环)脂族胺及其加合物,聚酰胺,曼尼希碱,酰氨基胺,酚醛树脂,咪唑和咪唑衍生物,双氰胺和BF 3 - 单乙醇胺。 它还涉及制备所述组合物的方法和由所述组合物制成的模制品。
