KINGSTON,Ontario–GrafoidInc.,aworldleadinggrapheneR&DandinvestmentcompanyannouncedtodayitsentryintotheglobalindustrialcoatingsmarketwiththeintroductionofitspatentpendingGrafeneXgraphenecoatingstechnology.GrafeneXisanoveltechnologythatcreatesaplatformforthedepositionofGrapheneandchemicallyfunctionalizedGraphenecoatings.ThisenablingprocessprovidesGrafoidwith thecapability toapply itsdiversegraphene-based coatings tomany different types ofmaterial substrateswith controllable levels ofsurfacecoverage,thicknessetc.tomeetpreciseenduserrequirements.Oneofthekeyobstaclestographene’sbroad,universalindustrialacceptanceistheabsencetodateoflow-cost,highperforminggrapheneapplicationsthatcanbesuccessfullyadaptedforuse across all industrial sectors. BCCMarketResearch reports the globalmarket forpaintsandcoatings isanticipatedtorise to$164.1billion in2021atacompoundannualgrowthrateof4.4%from2016-2021.Othermarketresearchindicatesevenhigherrevenuevalues.GrafoidPresidentandCEOGaryEconomodescribed theGrafeneX technologiesasacost-effectivewayoflayingdowngraphenecoatingsonlargesurfaceareas.“Demand exists for advanced multifunctional technologies capable of successfullydisruptingexistingbusinessmodels,”Mr.Economosaid. “Webelieveournovel, low-cost,coating technologies will encourage interest from those industries developing nextgenerationmaterialsandproducts.”AboutGrafeneXThe GrafeneX process applies Graphene based coatings to substrate materials includingpolymers,glasses,mostmetalsandrefractories(SeeFigure1).

A GrafeneX line can either be retrofitted to existingfinishinglines,orfunctionasastand-alonefinishingsystem.Mr.Economosaidthat theGrafeneX lineof technologiesandservicesareconsistentwithGrafoid’s businessmodel for long-term growth and revenue sustainability through jointventuring,licensingandfeesforservices.
