Elcora Conducts Tests to Develop Non-toxic Anti-fouling Graphene Coatings

Published on 2017-08-11. Author : SpecialChem

Elcora has announced the commencement of graphene-enhanced marine coatings tests. Elcora’s EL-2D few layer graphene powder supports the development of new and advanced graphene protective coatings.

They provide excellent hydrophobicity, chemical resistance, anti-bacterial properties, lubricity, strength and thermal characteristics.

Elcora Conducts Tests to Develop Non-toxic
Anti-fouling Graphene Coatings

  • Elcora has been developing a series of graphene-enhanced marine coatings
  • The hydrophobic nature of graphene has the potential to limit the growth of marine organisms
  • It educes fuel consumption of vessels through the reduction of drag forces
  • It increases the lifespan of coatings and provide de-icing properties

Anti-fouling coatings used in the marine environment prevents the growth of:
  • Barnacles
  • Mussels
  • Other organisms 

It contributes to increased fuel consumption of the vessel. It impedes mechanical functions and/or plugging of pipes.

Minimizing Use of Toxins in Marine Coatings

Common anti-fouling coatings use copper or other marine toxins. The first phase of Elcora’s tests investigates anti-fouling coatings on steel, with the purpose of minimizing the use of these toxins. A matrix of coating methods is being investigated that includes:
  • A direct coating of graphene
  • Epoxy composites 
  • An additive suitable to existing antifouling compounds

A comparison of biological organism growth will be made of the various graphene coatings according to standard ASTM testing methods. These will take approximately two months. The best-performing methods will than be optimized.

We are pleased with our initial coating test which demonstrates improved resistance to fouling and corrosion, even with a minor amount of dispersed graphene."

"Non-Toxic graphene based coatings could be truly disruptive to the Marine Coatings Market, which is said to surpass USD $15 billion by 2024 according to Global Market Insights” said Troy Grant, Elcora’s President & CEO.

NRC-IRAP-funded Project

Additional tests will be conducted based on the results of the anti-fouling investigation. These include:
  • Optimization of de-icing properties
  • Minimization in the differences of thermal expansion, strength, and other characteristics 

It will give these products a competitive advantage.

The National Research Council of Canada, Industrial Research Assistance Program (NRC-IRAP) has contributed $392,590 towards the successful completion of the project.
