GlossWell #240 Type Anti-Viral / FLOOR


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 # 240 Type ANTI-VIRAL / FLOOR mechanism

GlossWell # 240 Type ANTI-VIRAL / FLOOR is a one-part special ceramic paint (called binder) that has strong adhesion to various equipment, and special compounds with antiviral / antibacterial functions derived from ammonium are arranged. It has a structure.

GlossWell #240 Type Anti-Viral / Structure of LIGHT

 The following figure illustrates the mechanism by which the special quaternary ammonium salt contained in GlossWell #240 Type Anti-Viral / FLOOR 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.

GlossWell #240 Type Anti-Viral : A mechanism used to inhibit and suppress the growth of viruses.

Importance of special coatings with antiviral/antibacterial properties

For example, there are many products with antimicrobial function at the manufacturing stage, such as underwear, clothing, bedding, eyeglass frames, train leathers, cutting boards, shoes, etc. However, it is not easy to take antimicrobial measures against “things that are already there, things that exist, and things that cannot be moved. However, when it comes to antibacterial measures against “things that are already there, things that already exist, and things that cannot be moved,” it is not so easy. Although it is possible to “disinfect” such objects with ethanol, how many measures are available in the world to create an “antibacterial environment”?

The answer to this question was to develop a paint with anti-bacterial functions (anti-virus, anti-bacteria, anti-fungus). GlossWell #240 : Type Anti-Viral / FLOOR is a special paint created based on this concept, which provides excellent anti-sterilization performance, super water repellency, and super release performance against oil components. In addition, the entire coating is based on naturally occurring inorganic glass, which provides excellent adhesion (siloxane bonding) to various substrates. After complete curing, the paint film is colorless and transparent. The coating is very smooth to the touch, and there is no sense of discomfort in appearance even if it is applied to existing objects. Of course, anyone can use this product.

About anti-bacterial environment

An antiseptic environment is an environment that inhibits or prevents the growth of pathogenic viruses and bacteria in a variety of environments. In the case of viruses, they can only multiply within the cells they infect, but it has been confirmed that some viruses can survive for a relatively long time in general environments. In particular, preparing an antibacterial environment in advance for objects that are touched by an unspecified number of people and places that are considered to be dangerous is extremely important for preventing contact infection under the current situation of the new coronavirus, which appears to be spreading. In addition, it will become an important social point in the social environment from the viewpoint of public health after this crisis is over.

“Survival time of COVID-19 in the environment “
Airborne (when spread by coughing droplets): 3 hours
Copper surface: 4 hours
Cardboard surface: 24 hours
Plastic surface: 2 to 3 days
Stainless steel surface: 2 to 3 days

[ 2020.3/20 AFP ] : A research team from the Centers for Disease Control and Prevention (CDC), the University of California, Los Angeles, and Princeton University published data in the New England Journal of Medicine.

◯ Rotavirus, the causative agent of infant enteritis, can survive for more than 10 days in the general environment.
◯ The AIDS virus can survive for several days on the surface of various substrates in the general environment.
◯ Influenza viruses can survive for 8 to 48 hours in a general environment. etc.


Emergency : We are very sorry. The explanation is in Japanese only. We hope it will be of some help to you.

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.
