Laboratório de virologia Instituto de Biologia/Universidade Estadual de campinas in Campinas / Brasil did the test and the enclosed table shows the results after active corona virus was placed on test pieces which were coated with Bacoban® (Bacoban® was applied to the test substrates/pieces and allowed to dry before the active virus was applied).
The table confirms that the Bacoban® layer actively killed Corona Virus to a level of between log 4 and log 5 over the trial period.
This data shows the exceptional long-term performance of the active Bacoban® layer (see enclosed the original report + English summary).
