Abstract
This invention relates to materials and methods for obtaining strong adhesive bonds of coatings, composites and adhesives to proteinaceous substrates consisting either entirely, or in part of keratin, are disclosed. The invented materials comprise a non-aqueous solvent capable of adjusting the pH of the surface of the substrate to a pH of 8.0 or greater. The invented method comprises treating the substrate with the invented material until the pH of the surface is in the range of pH 9.0 to 11.0, followed by bonding a coating, composite or adhesive thereto.
