Abstract

The present invention relates to a kit for producing condensation cross-linking silicon mixtures containing bi-functionally terminated diorganopolysiloxanes, acetoxysilane cross-linking agents, and optionally, filling materials, suitable additives, pigments, colorants, anti-oxidation pigments, anti-heat pigments, and light-protection pigments in addition to solvents and plasticizers. Said kit contains water and an accelerator in the form of a basic neutral iron or aluminum salt with a mineral acid, especially an aluminum alum of ammonia and/or alkaline metals, as an accelerating cross-linking agent.
