PYLOTE, a specialist in mineral and ceramic industrial chemistry, and GERGONNE INDUSTRIE, a manufacturer and converter of technical adhesive tapes, announce that they have carried out major new tests on the effectiveness of COVERSAFE™, their antimicrobial protective film launched on the market since June 2020.
SARS-COV-2 TEST: COVERSAFE™ 96% effective after 1h contact time
COVERSAFE™ adhesive films have been tested according to the methodology of the ISO 21702 standard, within the Virology Department of the University of Limoges (Laboratory RESINFIT UMR Inserm 1092 & Microbiology Laboratory, CBRS, CHU of Limoges accredited COFRAC). Surfaces of COVERSAFE™ adhesive films activated by the PYLOTE technology were compared to similar control surfaces but without the technology. The contact of the COVERSAFETM film with the strain of human coronavirus SARS-CoV 2 strain BASA induced a reduction of the log viral load of 1.42 log after 1 hour contact time, i.e. 96% efficiency, persisting at 10 days of culture.
These results were obtained in an environment reproducing extreme conditions of use (greasy, voluntary soiling) of the surface known as “dirty hands conditions” which go beyond normal use.
TESTS IN REAL CONDITIONS CARRIED OUT BY BUREAU VERITAS:
COVERSAFE™ effective against microbiological transmission and contamination
COVERSAFE™ adhesive films have also been tested in situ in real conditions of use at the Xavier Bichat high school (600 students) in Nantua (Ain). The objective was to evaluate the biocontamination with or without the use of COVERSAFE™ antimicrobial protective films. The samples were taken from the main door of the school (used by several hundred people every day) and from a table in the catering self-service area.
The results demonstrate the very clear efficiency of the COVERSAFE™ adhesive film that allows a strong reduction of the risk of microbiological transmission:
- Main door of the high school (inside): division by 3 of the total flora present.
- Self-catering table (inside): division by 4 of the total flora present.
- Main door of the high school (outside): division by 2 of the total flora present.
All the surfaces equipped with COVERSAFE™ films have a value lower than the maximum target value of total flora of 50 CFU / 25 cm² (from the bio-cleaning guide), whereas only 33% of the surfaces without COVERSAFE™ films respect this value.
These completely independent results prove the performance of COVERSAFE™ adhesive films in real and extreme conditions (very high traffic) of use.
