Abstract:
PCT No. PCT/AT89/00116 Sec. 371 Date Aug. 2, 1990 Sec. 102(e) Date Aug. 2, 1990 PCT Filed Dec. 5, 1989 PCT Pub. No. WO90/06338 PCT Pub. Date Jun. 14, 1990.Premoulding materials having long-term controllable B-stage characteristic, comprising phenol resins, optionally with reagents, additives and adjuvants, are characterized in that they contain hydraulic binder and/or its components as well as an agent that reduces the alkalinity and optionally the content of free metal ions. For its preparation, 1 part by wt. phenol resin is mixed with less than 4 parts by wt. of a hydraulic binder and/or its components as well as less than 0.2 equivalent parts by weight of the agent. The phenol resin premoulding materials according to the invention thicken quickly to a desired B-stage, are capable of maintaining the attained plateau, and thus allow the manufacture of heat-curable composites of desired rheology and reactivity.
