The Blue Mussel (Mytilus edulis) Strong, non-toxic, underwater adhesion to multiple surfaces
Biomimetrics can meet the demand for wet-binging, non-toxic adhesives.
Synthetics will be used initially to ensure commercial viability.
Mussel Adhesive Protein Complex protein Difficult to purify or manufacture
Simplified Design Simple polymer backbone Catechol used in place of DOP
Poly (Catechol-Styrene) Exclusive license from Purdue Monomers commercially available Can use at scale at competitive cost

We have a wide competitive moat Three patents granted, two pending, others in process
Powerful underwater adhesion and bond strengths
Easily beat commercially available adhesives
Broad formulating via modifying the polymers or mixtures
PCS priming makes other adhesives stronger
Process: - PCS primer applied to a 1 sq in^2 area - Use steel (A36) or aluminum (2024) - High-grab polyurethane adhesive - Cure overnight - Binding strength assayed with an Instron 5567
Bond powerfully to wet surfaces
Combines with any chemistry
Utilizes known packaging
Thin coat primers
Long shelf life
One platform, unlimited potential Simply elegant - Makes existing bonds better
