Antimicrobial and Antiviral Coating with Superb Transparency, Adhesion, and Activity

Overview

There is a strong demand for antimicrobial and antiviral agents that are transparent, well adhere to the base material, and demonstrate antimicrobial and antiviral properties in a wide range of environments.

This transparent antimicrobial and antiviral coating offers all of these properties and is suitable for building materials, healthcare facilities, factory, textiles.

Feature 1. Antimicrobial and antiviral properties exhibited in a wide range of environments

Our transparent antimicrobial and antiviral coating has been tested using testing methods employed in SIAA* and other certification standards (e.g. ISO 22196, ISO 21702 and, ISO 18184) and has proven itself to exhibit high antimicrobial and antiviral properties against a wide range of bacteria and viruses regardless of whether it is in ultraviolet light, visible light, or in dark places.

Feature 2. High transparency avoids impairing the inherent aesthetic quality of the base material

The particle size of proprietary photocatalyst is small enough to exhibit transparency. Normally, particles tend to aggregate and become more cloudy with decreasing particle size; however, due to Osaka Gas’s proprietary technology, this material is satisfactory in both particle size and dispersibility. Therefore, this antimicrobiral and antiviral coating keeps transparency after being coated and rarely spoils the original texture and feel of the base material.

Feature 3. High adhesion

This material exhibits strong adhesion to the base material* without the use of a binder.* Normally, photocatalysts are used in combination with a binder to improve adhesion to the base material, but the use of a binder may reduce the antimicrobial and antiviral activity or change the texture. Due to the high adhesion provided by the photocatalyst alone, the transparent antimicrobial and antiviral coating of Osaka Gas has been proven to exhibit high adhesion without the use of a binder through tests assuming wiping with water.

* Adhesion varies depending on the type of base material.

Feature 4. Keeps the base material from deterioration

This material blocks ultraviolet rays and prevents deterioration in appearance and strength.

Feature 5. High photocatalytic properties

In an environment involving exposure to ultraviolet rays, this material exhibits the effect of decomposing organic dirt components and VOCs,* which are the cause of sick house syndrome, through its photocatalytic action.
