Abstract

The present invention relates to a catalyst for the cross-linking of silicone rubber materials with a cross-linker on the basis of lactate. In particular, the present invention provides a composition for the production of a silicone rubber material with a cross-linker on the basis of lactate, wherein the composition comprises a catalyst, which comprises at least two compounds, which are different from each other and which are selected independently of each other from metal salts of carboxylic acids. In addition, the present invention provides a method for the production of such a composition, as well as a use of the catalyst for the cross-linking of a silicone rubber material, in particular for cross-linking a silicone rubber material with a cross-linker on the basis of lactate, as well as a use of the composition of the present invention for the production of a silicone rubber material, in particular for use as a sealant, an adhesive, or a coating agent.
