Abstract

Official abstract text for this publication.

Adhesive formulations comprising bovine serum albumin, b-lactoglobulin, and/or a-lactalbumin can be applied and cured underwater to form a strong adhesive. Curing can be accomplished using heat or via a chemical denaturing component.

First claim

Opening claim text (preview).

What is claimed is: 1 . A method of forming an adhesive bond underwater, the method comprising: providing a first component comprising between 25 and 100% w/v (weight/volume) bovine serum albumin, b-lactoglobulin, and/or a-lactalbumin in water; providing a second component comprising 6-10M of a protein denaturant, 0.8-1.2M of a sulfur-containing reducing agent, 5-15% w/v of charged surfactant, and 10-45% w/v hard filler material; mixing the first and second components in a volumetric ratio in the range of 0.5:2 to 2:0.5 and contacting them with a first surface underwater; and then contacting the mixed components with a second surface underwater thereby forming an adhesive bond between the surfaces. 2 . The method of claim 1 , wherein the protein denaturant is urea, the sulfur-containing reducing agent is cysteine, and the charged surfactant is benzalkonium chloride. 3 . The method of claim 2 , wherein said components are mixed in a volumetric ratio of about 1:1.
