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.

The invention provides protein adhesives containing certain additives and methods of making and using such adhesives. The protein adhesives contain ground plant meal or an isolated polypeptide composition obtained from plant biomass in combination with certain additives, such as an exfoliated clay or partially exfoliated clay.

The invention relates generally to protein-containing polyurethane foams, methods and compositions for making the polyurethane foams, and articles comprising the polyurethane foams.

This invention provides emulsions and adhesives comprising proteins that can be isolated from a variety of sources including renewable plant biomass, and methods of making and using such emulsions and adhesives.

The invention provides protein adhesives and methods of making and using such adhesives. The protein adhesives contain ground plant meal or an isolated polypeptide composition obtained from plant biomass.

Bioactive coatings that include a base and a protein associated with the base for actively promoting the removal of organic stains are provided. In aspects, bioactive coatings that are stabilized against inactivation by weathering are provided including a base associated with a chemically modified enzyme, and, optionally a first polyoxyethylene present in the base and independent of the enzyme. The coatings are optionally overlayered onto a substrate to form an active coating facilitating the removal of organic stains or organic material from food, insects, or the environment.

Distiller's Grain (DG) based bio-adhesives consisting of DG biomass, crosslinking agents, and fillers are described as substitutes for formaldehyde based wood glue for making wood panels. Algal bio-adhesives consisting of algal biomass, crosslinking agents, and fillers are described as substitutes for formaldehyde based glue for making wood panels. Processes for preparing such DG based bio-adhesives and algal bio-adhesives are provided, comprising the steps of: combining DG biomass or algal material with a cross-linking agent and inorganic fillers to form a blend; micronisation or homogenisation of the blend to obtain powdery material; and mixing the powdery material with additional water to form a bio-adhesive.
