Trialling a graphene enhanced coating on a 33,000 tonne ship is “believed to be the single largest application of graphene” for improved corrosion protection performance compared with current practice.
“Thinking big is clearly the way forward for Talga as it starts a commercial-scale trial of graphene-enhanced coating on a 33,000-tonne container ship.
The advanced battery anode materials and graphene additives provider said the trial is believed to be the single largest application of graphene.
Talga Resources (ASX:TLG) added that the trial will serve as advanced testing of its functionalised graphene additive (Talphene®) as a performance booster for existing marine coatings – a part of the global 54-million-tonne-per-annum paint and coatings market.
Within this market, the marine coatings segment is projected to grow to $US12 billion ($17.4 billion) by 2024.
Graphene, which is composed of one atom-thick sheets of carbon atoms, has unique properties such as strength despite its light weight, along with heat and electrical conductivity that sets it apart from other forms of carbon.
While it typically does not mix well with other products, Talga’s bulk production methods ensures that its graphene has certain chemical bonds to bind it with other materials (functionalisation).
The company said the commercial-scale application follows the completion of in-house development and patent-pending technology that successfully translates graphene’s exceptional mechanical properties into paint and coatings.
Benefits are expected to include improved corrosion resistance, decreased metallic paint loss into oceanic ecosystems and increased efficiency through lowering dry-docking cycles.
Testing on steel panels coated with epoxy primer containing Talphene additive showed improved corrosion protection performance compared to “state of the art” commercial systems currently used world-wide in large volumes.”
