Alltimes Coatings’ Advantage for metal roofs is now more robust than ever, with added graphene!
Launched at the Advanced Materials Show, it’s still the same lightweight, re-coatable roofing system that roofers have come to depend on, but the addition of graphene creates a ‘tortuous pathway’ for water molecules, oxygen and salt to pass through. Put simply, it forms a barrier that is virtually impenetrable, giving unparalleled protection for your metal roof against corrosion and rust.
How does Graphene work?
Graphene possesses an unsurpassed combination of mechanical, electrical and thermal properties, and was first isolated in 2004 by Andre Geim and Konstantin Novoselov at The University of Manchester. They used sticky tape to remove single layers from the surface of graphite and deposit them onto a silicon wafer, and went on to receive the 2010 Nobel Prize for Physics for their discovery of this gamechanging material.
In its purest form, graphene has a molecular structure comprising of a single layer of carbon atoms bonded in a hexagonal structure. It is 200 times stronger than steel and it is the thinnest known material in existence, The addition of graphene to our Advantage roof coating has been made possible through Alltimes’ collaboration with Applied Graphene Material Ltd (AGM), who specialise in adapting particulate forms of graphene for dispersion into different materials, thus enhancing their resistance to atmospheric, marine or chemical elements.
Did you know Graphene... is 200 times stronger than steel, is the thinnest known material in existence, and forms a virtually impenetrable barrier?
AGM manufacture graphene, from sustainable sources, in a few atomic layers format for dispersion into coatings. They use processes to ensure their graphene is almost completely free of graphitic impurities, graphene oxide or transition metals, and, typically, just 1g of graphene in this form has a total surface area of over 350m2. It is graphene’s unique properties that give Advantage coating superior adhesion and flexibility, dramatically improving its life-expectancy.
Advantage Graphene has undergone rigorous testing to ISO:9227 with neutral salt spray for 5000 hours and is now an approved enhanced metal roof coating with industry-leading resistance to corrosion. The results are clear to see. It can still be applied in damp conditions, and is breathable, even through resting rainfall, to help maintain a constant building temperature.
