Mussel-Inspired Underwater Adhesives/Coatings From Renewable Resources

Tech ID: 23389 / UC Case 2013-562-0

Brief Description

A novel adhesive derived from renewable resources that can be used and applied underwater.


Current adhesive technology allows certain adhesives to be water resistant, creating a weather proof seal in harsh conditions. However, once an object is wet, most adhesives can no longer be applied. There is an increasing need for adhesives which can be applied under water or to already wet surfaces, such as boat hulls or undersea industrial equipment.


Researchers at the University of California, Santa Barbara have developed an adhesive which can be used and applied underwater. This material utilizes the adhesion techniques of California mussels and is produced using the plant derivative eugenol, which is an affordable and renewable resource. When tested underwater against the current commercial equivalent, it proved stronger, with a loop tack of 2.6 N/cm2 compared to 1.6 N/cm2.


  • Suitable for underwater use including ocean use
  • Produced using affordable and renewable resources
  • The monomer in this adhesive is readily formulated with other monomers and polymers


  • Perform boat/ship maintenance on the sea without the requirement of dry docking
  • Underwater adhesives/coatings including: 
    • Pressure-Sensitive Adhesives
    • Paints
    • Coatings
    • Inks
