Nippon Paint Group Releases PROTECTON BARRIERX™ SPRAY
Providing three-in-one anti-viral protection (quick inactivation of viruses, long life and durability), with just a quick spray on targeted surfaces

Nippon Paint Holdings Co., Ltd. (Head Office: Chuo-ku, Tokyo) announces that Nippon Paint Industrial Coatings Co., Ltd., a Nippon Paint Group company engaged mainly in manufacturing and sales of industrial coatings, is releasing PROTECTON BARRIERX™ SPRAY anti-viral and anti-bacterial spray on July 12.

PROTECTON BARRIERX™ SPRAY was developed by utilizing the visible light responsive photocatalyst technology of the Nippon Paint Group acquired through the development of paint and the unique immobilization technology of Nippon Paint Industrial Coatings. This product can be used to create a safe space at public places such as medical institutions, offices, living spaces, public transportation, and schools, where many people are in close contact.

This product has a high alcohol content to quickly suppress viruses and bacteria on surfaces. Visible light responsive photocatalysts in this product react even to weak indoor light such as fluorescent lights. These photocatalysts, combined with the effects of metallic ions also included in the product, produce a hybrid effect of anti-viral and anti-bacterial performance even under low light. The anti-viral and anti-bacterial protection is expected to last more than a month. In addition, the use of Nippon Paint Industrial Coatings’ unique immobilization technology is expected to enable the anti-viral and anti-bacterial coating film to withstand physical contact such as wet wiping.


Since the launch of the PROTECTON brand for paint and coating products with anti-viral and anti-bacterial properties in September 2020, the Nippon Paint Group has already released four anti-viral products for professional, DIY and home use. PROTECTON BARRIERX™ SPRAY is the fifth PROTECTON brand product.
