How Does Nature Solve
​Adhesion Problems?

The Blue Mussel (Mytilus edulis)
Strong, non-toxic, underwater adhesion to multiple surfaces
​Mussel peptides cure quickly underwater but are complex and prohibitively expensive
  • Biomimetics can meet the demand for wet-binding, non-toxic adhesives.
  • MPI's Synthetic version called Poly (Catechol-Styrene) ensures commercial viability.

PCS Bulk Adhesive
​Patented, Nontoxic, Affordable and Available today

  • Powerful underwater adhesion and bond strengths
  • Easily beats commercially available adhesives
  • Broad formulating via modifying polymers or mixtures
  • Comparable cost

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
