For many years, various new viruses have been harassing people's normal lives, and preventive measures are taken by humans to respond. Applying antibacterial and antiviral coating materials on indoor environment and objective surfaces is an important and effective means in daily life. Bacteria and viruses can be effectively killed as long as they come into contact with antibacterial and antiviral coatings.
STWD antibacterial and virus killing nanomaterial protective coating is made with water-based environmentally friendly resin as the film-forming material, and taking water-based dispersed nano metal ions and graphene derivatives as the main antibacterial and virus killing materials. Nanoscale and graphene grade materials enable it to efficiently kill viruses while not causing any harm to the human body and human cells. The synthesized coating material not only maintains high environmental standards (meeting the GB/T34676-2017 standard for interior wall coatings for children's room decoration), but also has excellent antibacterial and antiviral properties (stronger than the industry standard requirements in terms of resistance to bacteria, mold, and virus). It is a functional coating material that can be used by all types of people, safe, efficient, and has good decorative properties. It is pollution-free to the environment.
Product features/advantages
*The surface of the coating is dense and sturdy, resistant to scrubbing, and has high adhesion force
*Very good covering power, color adjustable, and good decorative effect
*Outstanding environmental performance, meeting the standards for children's room decoration materials and not releasing harmful substances
*Good antibacterial, antifungal, antiviral properties and durability, with an antiviral activity rate of over 99.9%
*Excellent waterproof and mold resistant performance
*Excellent scrub resistance, with no damage to the coating film after 10000 washes
*Waterborne coatings, environmentally friendly, non-toxic, odorless during application. It is easy for storage and transportation.
Product application scope
It can be widely used in hospitals, office buildings, conference and exhibition venues, as well as high-end decorative protection for antibacterial, antiviral, waterproof and interior walls of civil buildings.
