A release agent for vulcanized rubber molding is provided which has excellent mold releasing properties and washability. This release agent for vulcanized rubber molding contains an alkylene oxide adduct (A) of an active hydrogen group-containing compound having four active hydrogen atoms in the molecule, wherein the aforementioned alkylene oxide adduct (A) of an active hydrogen group-containing compound has a number average molecular weight of 5000-30000, and contains 50-95 mass % of an oxyethylene group.

Release agent for vulcanized rubber molding

A release agent for vulcanized rubber molding is provided which has excellent mold releasing properties and washability. This release agent for vulcanized rubber molding contains an alkylene oxide adduct (A) of an amine compound having 4-8 active hydrogen atoms in the molecule, wherein the aforementioned alkylene oxide adduct (A) of an amine compound has a number average molecular weight of 5000-30000, and contains 50-95 mass % of an oxyethylene group.

An anticaking agent for an iron and steel slag contains (A) at least one member selected from the group consisting of a phosphonic acid derivative and a salt thereof and (B) at least one member selected from the group consisting of an aliphatic hydroxycarboxylic acid and a salt thereof, at a mixing ratio (A)/(B) of the at least one member selected from the group consisting of a phosphonic acid derivative and a salt thereof (A) to the at least one member selected from the group consisting of an aliphatic hydroxycarboxylic acid and a salt thereof (B) of from 95/5 to 5/95 by mass, and the anticaking agent for an iron and steel slag may further contain (C) a sugar alcohol, thereby providing further high synergistic effect on anticaking capability.
