Abstract (en)
[origin: EP1180551A2] Hardening protective mass based on materials forming boron glass contains magnesium-silicon compounds as additive. Preferred Features: The materials forming boron glass and the magnesium-silicon compounds are present in the ratio of 2-100: 1, preferably 10: 1. The magnesium-silicon compounds are magnesium silicates such as magnesium orthosilicate, magnesium metasilicate, magnesium trisilicate or talc. The materials forming boron glass are selected from boric acid, boron oxide, alkali borate and alkaline earth borate.
