Keep safe from virus infection risks with the technology
of destroying cell walls and keeping similar viruses away.


Highly effective to daily cleaning, even to the spots out of reach away.

Hospital and public facilities where entrance/ exits exist muturaly could cause the risk of the infection especially doorknob, switch, button, desk, handrails. Daily prevention is hard to be enough, spots could be left no matter how However by spraying Si Shield in advance, which contains  antibacterial , antiviral and deodorizing action could be effective to any 
corners where human hands could not reach. This operation minimizes  contagion risks and maximize the virus control.

Results of high level Safety

Testing organization: Japan Food Research Laboratories SafePharm Laboratories (UK) * GLP compliant OECD 404/406/471/405 compliant

Proof of effectiveness and safety through viral testing


Testing organization: Japan Food Research Laboratories * Detection limit: 1.3 × 10 × 10 TCD50 / MI * Infection value reduction value: log10 (0 minute infection value ÷ 1 minute action time infection value)

In the condition of applying Si Shield liquid into virus of initial infectivity titer 1.1 × 10⁵ TCID 50/mL, experimental result concluded that infectivity titer is reduced by over 2.9log₁₀(below infectivity titer 1.3 × 10² TCID50/mL)

Thin film adhesion effect

Silica nanocolloid technology is realized!

Thin film adhesion effect

The surface of familiar materials has very fine irregularities, and microorganisms and dirt are attached to them.

1 Wrap the organic conjugate

2 Antiviral function

3 layers and effect


Envelops organic bonds with the binding force of silica nanocolloids and coats nano-level irregularities.


Antibacterial and antiviral performance is imparted by silica coating fine irregularities.


Silica that has penetrated to nano-level unevenness increases the number of layers as the construction is repeated, and the effect lasts longer.

Repellent effect

Since it keeps bacteria away, it is difficult for resistant bacteria to form!

Asphyxial bacteria transmit repellent signals and keep the same species away. Since it is difficult to develop resistant bacteria, the bacteria will eventually die.

1 Destroy the cell wall of the bacterial nucleus

Repellent message

Si-Shield, a silica nanocolloid, destroys the cell wall (cloak) of the fungus nucleus.

The nucleus of the fungus whose mantle has been destroyed becomes asphyxial.

The nucleus of the asphyxial fungus gives a danger signal to the same kind of fungus and keeps it away.
