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.
