Abstract
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.
Claims9
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.

A composition for underwater adhesion, the composition comprising:
- a first component comprising between 25 and 100% w/v (weight/volume) bovine serum albumin, b-lactoglobulin, and/or a-lactalbumin in water;
- and
- 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.
A dispenser of underwater adhesive, the dispenser comprising:
- a first chamber containing a first component comprising between 25 and 100% w/v (weight/volume) bovine serum albumin, b-lactoglobulin, and/or a-lactalbumin in water;
- a second chamber containing 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;
- and
- a nozzle in fluidic communication with each of the two chambers, wherein the first and second components are present in a volumetric ratio in the range of 0.5:2 to 2:0.5.
