About

Mussel Polymers develops Poly Catechol Styrene (PCS), a synthetic adhesive polymer that mimics the chemistry mussels use to attach to surfaces underwater. The compound was invented at Purdue University with Office of Naval Research support and is licensed by the company, which develops and manufactures the adhesives in-house in Bethlehem, Pennsylvania. The company reports PCS bonds roughly 300% more strongly than other commercial underwater adhesives while remaining nontoxic. Lead applications are dental and biomedical products, with additional targets in coral restoration, ship repair, defense and industrial bonding.

PCS bonds in wet, high-moisture and low-surface-energy conditions where conventional adhesives fail, and does so nontoxically, which is what opens both intraoral dental use and marine applications like coral restoration and ship repair.
