12/28, 2020 : Inactivation of COVID-19 has been demonstrated by a third-party organization.
December.28,2020 : QTEC (Kobe Testing Center, Japan Textile Products Quality Technology Center) has demonstrated that COVID-19 can be inactivated.
The antiviral and antimicrobial compound (special quaternary ammonium salt) contained in GlossWell #360 Type Anti-Viral has been proven to inactivate COVID-19. The special antiviral and antimicrobial coating of GlossWell #360 Type Anti-Viral has a strong adhesion to the surface on which it is applied, and it also reduces viruses and bacteria on the coating within a short period of time (99.9% reduction after 10 minutes). We hope that COVID-19 will help reduce the risk of contact infections by creating an antiviral environment through coating in areas where many people come into contact with it or where droplets must be avoided.

GlossWell # 360 Type ANTI-VIRAL mechanism
GlossWell #360 Type Anti-Viral is a one-component special ceramic coating (called a binder) with strong adhesion to a variety of materials and an array of special quaternary ammonium salts (proven to be effective against new coronaviruses) as anti-viral and anti-bacterial ingredients.
▼ The following figure illustrates the mechanism by which the special quaternary ammonium salt contained in GlossWell #360 Type Anti-Viral inhibits and suppresses the growth of COVID-19 and other viruses with envelope membranes (such as influenza A viruses). Quaternary ammonium salts, which are also surfactants, disrupt the lipid bilayers and membrane proteins of the envelope of COVID-19. The virus dies when the envelope membrane is destroyed.

Advantages of special agent with antiviral and bacterial functions
Advantages of special agent with antiviral and bacterial functions.For example, there are many products that have an antibacterial at the manufacturing stage, such as underwear and clothing, bedding, eyeglass bleeding, hanging leather as in the trains, cutting boards, shoes, etc. These are not going to be straightforward when it comes to antibacterial measures against “things that exist in / things that cannot move.” It is possible to “disinfect” things with ethanol but when you try to create an “antibacterial environment”, how would it be? Can you really do this in the world? The solution was developed a some paint agent with antibacterial products (antivirus / antibacterial / antifungal). But it is a liquid , it is just to painting there, so “things that are already there / things that can not move”, and even if it is a complicated shape, furthermore you can freely create an antibacterial environment regardless of the products size with construction surface.
GlossWell # 360: Type Anti-Viral was developed a special agent based on such an idea, with excellent antibacterial performance (antivirus / antibacterial / antifungal), super water resistance and super release oil components performance. In addition, inorganic glass that exists in the natural world is the base of the entire coating material, and its properties make use of its strong adhesion to various substrates (siloxane bond). The coating after complete curing is clear base and transparent. The feels also very smooth, and there is no discomfort even if existing items are covered with an antibacterial environment as veil. Since this agent is completed with only one coat, the installation method is extremely simple. Of course anyone can do this by your self.

Precautions for painting
○ Coating environment: Avoid using in an environment with poor ventilation.
○ Pretreatment: Oil, water, and dirt on the surface of the material should be sufficiently removed by solvent degreasing.
○ Painting: Paint immediately. Leaving it for a long time may cause clogging and uneven coating.
・ Manage the film thickness within the specified range.
○ Drying: Organic gas is generated during drying, so provide sufficient ventilation / exhaust.
○ Storage: Store the paint in a cool and dark place.
・ This paint has the property of reacting with moisture in the air. Please seal it after use.
○ Disposal: Follow the MSDS (Material Safety Data Sheet) for disposal of paint residue and waste liquid.
○ Handling Precautions: Do not use in a place with a fire because it uses a flammable organic solvent.
・ Be careful not to come in contact with skin and mucous membranes, especially eyes, as they are irritating.
・ In case of contact, wash with plenty of water.
○ Others: Refer to the product MSDS for details.
