Adhesives derived from bioadhesive polyphenolic proteins
First Claim
1. A water-imperious adhesive or coating formulation exhibiting an adhesive strength of at least about 100 gm/cm2 when used on soft tissue comprising:
- (1) a bioadhesive polyphenolic protein component having from about 5 to about 99 weight percent of a proteinaceous substance comprising from about 50 to about 150 of the following repeating decapeptide unit;
##STR4## in which each X is hydrogen or hydroxyl, and each R is hydrogen or methyl;
(2) from about 1.0 to about 40 weight percent of a cross-linking agent which promotes cross-linking of the decapeptide;
(3) one or more additives which promote the desired properties of the formulation, said additives comprising at least one surfactant and being present in an amount of from 0% to about 90% by weight, and(4) a filler compatible with the intended use of the formulation, said filler being present in an amount of from 0% to about 50% by weight,wherein the bioadhesive polyphenolic protein component (1) is derived from the marine mussel.

Abstract
An adhesive or coating formulation useful in biomedical application and particularly well suited for use in aqueous environments is provided comprising:
(1) a bioadhesive polyphenolic protein component having from about 5 to about 99 weight percent of a proteinaceous substance comprising from about 10 to about 400 of the following repeating decapeptide unit: ##STR1## in which each X is hydrogen or hydroxyl and each R is hydrogen or methyl; (2) from about 1.0 to about 40 weight percent of a cross-linking agent which promotes cross-linking of the decapeptide;
(3) one or more additives which promote the desired properties of the formulation, said additives comprising at least one surfactant and being present in an amount of from 0% to about 90% by weight, and
(4) a filler compatible with the intended use of the formulation, said filler being present in an amount of from 0% to about 50% by weight.
