In a process for producing this reaction resin curing agent preparation, either the reaction resin and, separately from it, the curing agent are formed into droplets and the surface of the droplets thus formed is enveloped with a dusty material, especially with silica, the pulverulent resin material and the pulverulent curing agent material thus obtained separately from one another are then mixed together, or a processable fluid mixture of a quantity of reaction resin and a quantity of curing agent is produced and, before the end of curing, an organic acid, which reacts with the reactive groups, then still free for the reaction, of the curing agent and neutralises these, is added to this mixture. Here again, the end product is pulverulent.
