Abstract: The present invention is directed to a curable and electrochemically debondable two-component (2K) adhesive composition comprising: a first component comprising: i) at least one polyol selected from the group consisting of fatty alcohols, polyester polyols, polyether polyols, polyether-polyester polyols and polycarbonate polyols: ii) optionally further active hydrogen compounds: and, iii) non-polymerizable electrolyte: and, a second component comprising at least one polyisocyanate, wherein said composition is characterized in that the molar equivalents ratio of NCO groups to active hydrogen atoms is at least 1:1.

Abstract: The present invention relates to aqueous peptide-functionalized polyurethane dispersions that can be used as adhesives, in particular for metal surfaces, such as steel surfaces. As hybrid materials, they provide for a versatile system that can be finely tuned and combine the advantageous properties of polyurethane and peptide materials. Also encompassed are processes for their production, compositions containing them and their use as coatings and adhesives.
