ANTI-MICROBIAL CONFORMPROTECTIVE FILM
714-575-1100 www.Graffiti-Shield.com
Tested by third party to ISO testing standards against most common illness-causing bacteria and coronavirus. Antimicrobial technology is applied to the product; it does not directly protect the user from any exposure to bacteria or viruses, or provide additional health benefits. Pure Zone antimicrobial film contains an active ingredient (silver ions approved by EPA under file number 73148-1-91742). Pure Zone has been tested and proven to reduce Coronavirus by up to 99.87% (after 1 hour) and reduce up to 99.99% of bacteria (after 1 hour) such as: Listeria, Salmonella, Golden Staph, Methicillin-resistant Staphylococcus aureus, and Pseudomonas aeruginosa. It is strongly recommended to practice good hygiene, wash hands regularly, and maintain social distancing as often as possible.
During cleaning operations, as well as in the presence of humidity, silver ions are released from the top layer of the film. These ions come into contact with the bacteria, blocking their metabolism and/or interrupting their proliferation mechanism, leading to their destruction When the Anti-Microbial film is manufactured, silver ions encapsulated in a glass matrix are distributed over the film in a uniform manner.
Active strains (according to ISO 22196)Reducing > 99.99 % of bacteria ascertained for:
• Escherichia coli• Salmonella (Salmonelle enterica)• Listeria (Listeria monocytogenes)• Golden staph (Staphylococcus aureus)• Methicillin-resistant Staphylococcus aureus (MRSA)• Pseudomonas aeruginosa
Antiviral activity on the Human coronavirus HCoV-229E strain (according to the ISO 21702 standard):
• 94.99 % after a contact time of 15 minutes• 99.87 % after a contact time of 60 minutes
Under normal usage conditions, harmless when in contact with human skin (skin compatibility study carried out under dermatological control). • No allergenic potential • No irritant potential
• Active compound: silver ions, < 0.3 % w/w of the entire product
• Antimicrobial activity maintained after 365 cleanings with water, alcohol, and chlorine bleach
• Resistance to solvents: the adhesive is resistant to most chemicals (alcohol, diluted acids, oils). The film can be cleaned/disinfected by all conventional cleaning methods, using non-abrasive accessories, cleaning products, detergents or products currently used in healthcare environments
• The disinfection levels achieved are compatible with common usage in the most sensitive areas in terms of infectious risks
• Recommended minimum application temperature: +10 °C (+50 °F).
• Operating temperature range: from -40 °C to +90 °C (-40 °F to +194 °F)
ANTI-MICROBIAL CONFORMPROTECTIVE FILM

Anti-Microbial film applied in areas of frequent handling (e.g.: handles) or high visitor frequency will be subject to repeated abrasion which will reduce its durability (change of appearance, lifting, etc.). The film durability depends on the intensity and frequency of the mechanical stress to which it is exposed.

THE ANTI-MICROBIAL ACTION OF SILVER IONS
In its (elemental) metallic form, silver is inert and does not kill bacteria. Silver atoms (written as Ag or Ag0) must lose an electron and become positively charged silver ions, Ag+. Silver is ionised in air, but above all in a humid environment. Silver ions are highly reactive and affect multiple sites in bacterial cells, guaranteeing their destruction.
SILVER IONS : • Produce alterations to the
cell wall
• When transported into the cell, bind with proteins and interfere with the production of energy, enzyme function and cell replication
• Silver ions are active on a broad spectrum of bacteria

Difference < 1 log10 ☒ yes ☐ no
Comparative titre of human coronavirus HCoV-229E on MRC5 cells inoculated with
PUREZONE060/PRZ150/PURECOVER surface and stainless steel surface recuperation buffer show
a difference less than 1log10. Results showed that recuperation buffers of the test surfaces didn’t affect
the MRC5 susceptibility to human coronavirus HCoV-229E under test conditions.
a. Cytotoxicity
The test surface cytotoxicity is determined by reading of cytopathic effect (CPE) on MRC5 permissive
cells and quantified by TCID50 technique.
For viral recuperation on surface, the surfaces are submerging in 2mL of infection medium without
FCS (recuperation buffer). The recuperation buffer cytotoxicity is determined by reading of cytopathic
effect (CPE)
Under test conditions, the recuperations buffers from PUREZONE060/PRZ150/PURECOVER and
stainless steel surfaces didn’t show cytopathic effects on MRC5 cells for a contact time of 15 and 60
minutes.
The test results are dependant and take into account the cytotoxicity results.
