摘要: Binders are described based on acid curing phenol resins and acid curing agents which, after mixing, have an extended processability time but nevertheless exhibit a rapid curing time at relatively low temperatures. They are obtained by using, as the resin, aqueous phenol resols and, as the curing agent, either copper, aluminum, or iron(III) salts of aromatic sulfonic acids or addition products of hydroxy-containing, water-compatible polyols with aromatic sulfonic acids or mixtures of these salts and the polyol addition products. The binders are used for impregnation of fabrics, for production of abrasives and for fiber reinforced plastics.

摘要: In the process according to the invention molding compounds based on duroplastic bonding agents are produced thereby that the bonding agents are mixed as a melt with the filler and additive substances. Curing is achieved thereby that the temperature of the mixture during the mixing process increases above the onset temperature of the curing reaction and, after the desired degree of curing has been attained, is suddenly lowered.
