Shin-Etsu Chemical Co., Ltd. рas developed “Tersus RN,” an inorganic thin-film coating liquid which possesses antibacterial/antivirus functions, envisioning its application for building materials for housing and buildings, said the company.
The Tersus Series, which uses Shin-Etsu Chemical’s own unique silicate as an ingredient, is a coating liquid that forms a transparent thin film of natural finish that does not interfere with the building materials’ design. The newly developed Tersus represents a new line-up in the series, and it has 2 kinds of nano particles as active ingredients, titania and silver, which can realize antivirus functions.
In the background leading to the development of this new product, there has been a rising of hygiene consciousness towards building materials in the midst of the coronavirus pandemic. At an external testing laboratory test*1, it was verified that on the surfaces where these products were applied, there was a high antivirus function exhibiting a strong inhibitory effect against the novel corona virus (SARS-COV-2), of 99.94% (R=3.2).
In addition, with regard to the general antibacterial/antivirus performance, Shin-Etsu has also obtained the certification of The Society of International sustaining growth for Antimicrobial Articles (SIAA).
This product is a water-based coating liquid and there is no worry about offensive odors or adverse effects on the human body at the time of application operation, which in the case with an organic-solvent-base becomes an issue.
This product will meet your expectations by realizing a highly hygienic environment, not only for use in environments where large numbers of unspecified people gather, such as offices, hospitals, public facilities, nursing facilities, automobiles and railway cars, but also for use as a coating liquid for various residential building materials.
We remind, on 16 Feb 2022, Shin-Etsu Chemical Co Ltd announced plans to invest over $695 M to expand its silicone manufacturing plants across Japan to meet a very strong demand for advanced functional products. According to the company, the new plant investments will expand the manufacturing capacity of "highly diversified" kinds of silicone resins, fluids, and rubber end products by 2025. The expansion project will start with Shin-Etsu's main facility, the Gunma Complex in Gunma Prefecture, and will be followed by two other facilities in Naoetsu, Niigata Prefecture, and Takefu, Fukui Prefecture.
