    Abstract: The present invention relates to an one-component adhesive composition, comprising a moisture cross-linking silyl modified polymer and an organoclay-based rheology controller being an alkyl ammonium salt modified mineral clay mixture. The present invention relates moreover to a two-component adhesive composition, comprising a first component A) comprising a moisture cross-linking polymer and an organoclay-based rheology controller; and a second water-based component B) that is reactive with component A) upon mixing thereof. The present invention moreover relates to a method of production of said adhesive composition.
