Abstract
The invention describes a sprayable composition, the use thereof, and a method for sealing openings or gaps in components. Described are a sprayable and stable composition comprising at least one organopolysiloxane that contains hydroxyl groups and / or hydrolysable groups, at least one crosslinking agent based on a functionalised silane, at least one filler based on silicon dioxide, and at least one condensation catalyst; the use thereof as a coating; and a method for sealing openings or gaps in components.
Description
technical field [0001] The present invention relates to compositions based on moisture-cross-linking organopolysiloxanes, their use as sealants and methods for sealing openings and gaps in building components. Background technique [0002] It is known in the prior art to seal gaps (hereinafter also referred to as “joints”) between building components, such as walls, for example with sealants during the construction of buildings. In building technology, a desired or permissible gap or intermediate space between two building components or materials is called a joint. A common use is the (fire-proof) sealing of so-called connection joints or sliding joints, which occur, for example, in overhanging building facades. A connecting seam necessarily occurs when two different parts of the same or different materials are placed against each other. For this purpose, the insulating material is usually first inserted and then the sealant is applied, preferably by spraying. [0003] In...
