摘要

Anchoring casing with a reactive charge to produce synthetic resin bodies for adhesive binding of fixing units in a fixing base comprises an outer tubular casing contg. a liq. resin components (a) and an inner casing contg. granular filler (b) and curing components (c). The inner casing contains a mixt. of (b) laden with (c) and (b) laden with an accelerator (d), and the remaining space in the inner casing is filled with oxygen-rich gas. The components (a) comprise 51-100 (75-100) pts. wt. 2,2-bi(4-(methacryloxy-ethoxy)phenyl)propane and 49-0 (25-) pts. wt. unsatd. polyester, vinyl ester and/or acryl resin. Pref. reactive charge comprises 34-44 pts. wt. (a) 50-70 pts. wt. filler (b); 1.0-2.0 organic peroxide as curing agent (c); and 0.2-0.7 pts. wt. accelerator (d). Pref. (a) includes non-reactive organic diluent(s) esp. acetone, dimethylformamide, toluene, methyl ethyl ketone, dibutyl or dimethyl or dihexyl phthalate, or mixtures of these; and additional monomers esp. styrene, methyl methacrylate and/or ethylmethacrylate. USE/ADVANTAGE - For attachment to rock, walls, concrete etc. The multi-chamber anchoring unit has good storage stability and forms a resin body with little vol. los
