Abstract

Two component adhesive/sealing masses based on silane terminated prepolymers contain a component A which is a one-component, humidity hardening adhesive/sealing mass with high initial adhesiveness, and a component B which is a crosslinking agent and/or accelerator for component A are disclosed. These adhesive/sealing masses are suitable for gluing without primer parts made of metals or other materials such as aluminum, steel, glass, wood or plastics. In a particularly preferred embodiment, component B consists of a viscous, stable mixture of plasticisers, water, thickeners and other optional auxiliary substances.
