Invention Summary

Each year billions of pounds of adhesives and coatings are used. Most non bio-based adhesives and coatings contain hazardous chemicals such as vinyl acetate, acetaldehyde, and various other chemicals that may cause skin and eye irritation. Additionally the vapor produced from adhesives during processing and use may cause respiratory tract irritation and some are even considered to be carcinogenic.

Advantages

The invention provides for "Surface Active and Interactive Protein Polymers" (SAIPP) which can be manipulated via the understanding of the hydrophobic and hydrophilic properties of the materials and the resultant changes in pH that must be imposed to deliver designer bio-based adhesives and polymers. The proteins used in making these materials may be selected from several natural sources such as soybeans, corn, wheat, other cereals and oilseed crops, as well as animal proteins. The SAIPP can be used as a liquid, semi-liquid, or in a powdered form depending on the specific application.

Applications

• Adhesives for wood veneer, children's glue, labeling, packaging sealant

• Hot melt adhesives that are highly water resistant

• Powdered from can be blended with other polymers and fiber for molding composites

• Interior home paints

• Paper coatings

• Foundry binders
