GC HALO®

Dual action Nanotechnology - 'trap and kill' surface coatings

GC has developed a pioneering formulation, GC Halo® that destroys pathogens by forming a ‘trap and kill’ layer on air filters. Fast-acting, safe and more than 99% effective against SARS-CoV-2 coronavirus, flu, bacteria and mould. Independent tests and certifications prove GC Halo’s capabilities as a filter coating to deliver cleaner and safer indoor air.

GC Halo is a breakthrough technology, providing superior, long-lasting protection with broad applications where health, safety, and wellbeing are paramount.

Introduction to GC Halo


HOW GC HALO® WORKS

GC’s technology is highly effective due to its dual action mechanism. The negatively-charged graphene oxide surface traps the positively-charged parts of water droplets and the protein spikes on coronavirus and other viruses. The silver nanoparticles oxidise the lipid membrane protecting coronavirus RNA, thereby killing it.

  • 100% virucidal efficacy on Human Coronavirus OC43 and Influenza A H1N1 viruses in liquid form, in less than one minute. Independently tested by Brown University
  • At least 99% virucidal efficacy on textiles. Independently tested in the UK according to ISO 18184:2019GC’s technology is highly effective due to its dual-action mechanism: the negatively-charged surface of graphene oxide traps the positively-charged parts of water droplets and the protein spikes on coronavirus and other viruses; the silver nanoparticles oxidize the lipid membrane protecting coronavirus RNA, thereby killing it.
    • 100% virucidal efficacy on Human Coronavirus OC43 and Influenza A H1N1 viruses in liquid form – in less than one minute, independently tested by Brown University
    • At least 99% virucidal efficacy on textiles, independently tested in the UK according to ISO 18184:2019
    • GC Halo® coated air filters proven 99.99% efficacy against mould (Aspergillus brasiliensis)
    • Proven to destroy over 99.99% of Staphylococcus aureus and Escherichia coli
    • No observable ink particulates in airflow tests
    • Independently tested to have no measurable impact on airflow
