Sealant and adhesive

One-component, moisture-hardening sealants and adhesives contain telechelic isocyanate prepolymers obtainable by reacting diisocyanates and/or polyisocyanates in stoichiometric excess with polyester polyols, polyether polyols and hydroxy-functional (meth) acrylate prepolymers, as well as conventiona...

Beschreibung
Zusammenfassung:	One-component, moisture-hardening sealants and adhesives contain telechelic isocyanate prepolymers obtainable by reacting diisocyanates and/or polyisocyanates in stoichiometric excess with polyester polyols, polyether polyols and hydroxy-functional (meth) acrylate prepolymers, as well as conventional plasticizers, the polyester polyols having branches, more particularly formed by alkyl radicals containing no functional groups. The polyester polyols can either be obtained by reacting corresponding branched diols and/or dicarboxylic acids or by subsequent grafting of side groups on to straight-chain polyester polyols. The sealants and adhesives are transparent or translucent, have a high ageing stability and excellent mechanical characteristics.
