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： An improved method for preparing a molding material for abrasive articles has been developed. The method includes the step of continuously blending an abrasive material with a curing agent and measured portions of two phenol-novolac resins, one of which has a phenol-formaldehyde molar ratio in the range of about 1:0.2 to 1:0.35. The blending composition can also include various other materials, such as fillers. The resulting product is a flowable, granular material homogeneously coated with the phenol-novolac resins. The product can be directly molded, i.e., without an aging step, into various abrasive articles, such as grinding wheels.In another embodiment, either a continuous or discontinuous technique can be used to blend the phenol-novolac resins, and the molded product is then cold pressed or warm pressed at a pressing temperature less than about 140.degree. C.
