Developed by ERST Project GmbH, WATERLIQ is a water-based disinfectant that has proven to be effective against viruses similar to the SARS-CoV-2 virus on hard, porous, and non-porous surfaces, according to microbiological laboratory test reports.

Fine droplets of WATERLIQ can instantly kill 99.9% of pathogens and be used at entrances and exits of local clusters and quarantine locations to disinfect and prevent further spread of the virus.

The teams are working to apply the longer-term clear surface coating of ERSTOTIZER & Nomobac on the hard and absorbent surfaces within the dormitories.

The ERSTOTIZER & Nomobac after applied on surfaces will last between 6 to 24 months where various types of viruses, bacteria and microbes will have no chance to survive.
