MPCD01: A Powerful, Mussel-Inspired Anti-Corrosive Tie-Coat

MPCD01 relies on our proprietary synthetic polymer, Poly(Catechol-Styrene), or PCS. PCS is a ōbiomimeticö polymer that replicates the structure of adhesive proteins that are used by blue mussels to adhere to a range of substrates in the ocean. PCS is a strong adhesive, performing especially well in wet conditions, and even underwater. Poly(Catechol-Styrene) is a non-toxic compound composed of styrene and catechol chemical functional groups. The catechol groups within PCS are the driving force behind its robust adhesive and anticorrosive properties. PCS leverages catechol chemistry to adhere strongly to a variety of surfaces, whether wet or dry. These surfaces include aluminum, steel, carbon steel, urethanes, epoxies, acrylates, plastics, and others. Moreover, the catechol groups enable PCS to function as a powerful standalone anticorrosive agent (Patent Pending). MPI is collaborating with research partners to delve into the reasons behind PCS's potent anticorrosive activity. Current research points to several potential factors. These include the selective coating and protection of areas prone to corrosion on the substrate, the inherent antioxidant activity of catechol, and even the self-healing capacity of polymers containing catechol functional groups. The unique properties of PCS make it a perfect match for use in Tie-Coats and other coating applications. This chemical versatility results in protective coatings highly resistant to peeling. Mussel Polymers is collaborating with U.S. Navy researchers at NSWC-Carderock Division (Potomac, Maryland), research contractors at Elzly Technology Corporation (Vineland, New Jersey), and consultants from Chemical Dynamics (Plymouth, MI) to develop MPCD01. The USMC is now testing MPCD01 in field applications to assess its ability to prevent CARC coating delamination and corrosion on deployed equipment. MPI is also in talks with PPG for a potential collaboration on the further development of adhesion-promoting Tie-Coats using MPI's technology. Preliminary independent experiments conducted by PPG have demonstrated the efficacy of PCS as an adhesion promoter for sealants and coatings on various substrates. Given PPG's extensive knowledge and experience as a leading global coatings producer, they could potentially add significant value to this project as a collaborator with MPI.
