Creating new barriers with graphene

Tuesday, 30 August 2016

An independent test programme investigating the addition of graphene nanoplatelets (A-GNPs) to epoxy coatings, has shown significant performance enhancements across industry ISO standard anti-corrosion and barrier tests.

The tests were carried out by PRA, an independent testing consultancy, and demonstrated that very small additions of A-GNPs decreased water vapour transmission rates by up to 95% and extended time to initial corrosion in excess of 500%.

Results were achieved with dispersions

The results were achieved with dispersions based on Applied Graphene Materials' (AGM) continuously synthesised graphene nanoplatelets. Supported by strong in-house coatings and product integration expertise, AGM has already entered several product development programmes, the latest results and low loading levels helping to highlight the technical and commercial viability of this new technology. AGM is keen to find other development partners within the coatings industry with a desire to create new technology and barrier systems.

Comment from Steve Ryley, Technology Manager, PRA

"The results from our test work are very interesting and support the findings of early investigation programmes with A-GNPs in both epoxy and polyurethane coatings. Our findings clearly show that well dispersed A-GNPs offer the potential for significant enhancements in barrier and anti-corrosion performance in coatings.”
