Disclosed are an additive composition for an adhesive composition as well as an adhesive composition itself that is based on starch, dextrin or polyvinyl alcohol as the adhesive component. The additive composition includes a cross-linked carbomer and a metasilicate of an alkali metal or an alkaline earth metal in a ratio between 0.50 and 5.00, and with the metasilicate being present in a concentration of at least 1.70% wt in the additive composition in the form of a dry powder mixture. Further disclosed are kits in parts as well as a method for the production of these products, as well as uses for these products.
An additive composition for an adhesive composition, the additive composition being in a form selected from an aqueous composition, a dry powder mixture and a kit in parts, and the additive composition comprising a cross-linked carbomer and a metasilicate of a metal selected from an alkali metal, an alkaline earth metal, and combinations thereof, wherein the carbomer and the metasilicate are present in the additive composition in a weight ratio of carbomer over metasilicate which is higher than 0.50 and at most 2.50, and wherein, if the additive composition is in the form of a dry powder mixture, the metasilicate is present in the dry powder mixture in a concentration of at least 1.70% wt.
