Three Categories of Antibacterial Agents Used in Antiviral Waterborne Paint

Antibacterial coatings are coatings whose surface possesses antibacterial properties and can inhibit the growth of bacteria and microorganisms.

Such coatings are mainly used on walls, countertops, door handles, kitchen utensils and other high-touch areas, industrial products, and HVAC vents. They can also be applied to gloves, masks, carpets and textiles.

When used on walls and surfaces in medical facilities and hospitals, they can reduce cross-infection in hospitals.

In the current context of the novel coronavirus pandemic, antibacterial coatings also play a certain role in blocking and inactivating viruses.

The antibacterial function of antibacterial coatings is mainly derived from antibacterial agents added to the paint.

It can be said that the main difference between antibacterial coatings and ordinary coatings lies in the selection and addition of antibacterial agents.

I. Categories of Antibacterial Agents

At present, antibacterial agents for coatings mainly fall into three categories: natural antibacterial agents, organic antibacterial agents, and inorganic antibacterial agents, with different antibacterial effects.

Natural antibacterial agents

Such as chitin, mustard seed, castor oil, wasabi, etc. They are easy to use but have limited antibacterial effects and cannot provide broad-spectrum and long-lasting protection.

Organic antibacterial agents

Such as quaternary ammonium salts, thiocyanate compounds, sorbic acid, etc. They feature fast sterilization speed and mature development and application technologies, but have poor stability and long-term effectiveness.

Inorganic antibacterial agents

Mainly including metal powders or ions, photocatalytic types, etc.

Metal-based agents mainly include Ag, Cu, Zn, etc.

Photocatalytic types include titanium dioxide, zinc oxide, etc.

Among inorganic antibacterial agents, silver ion and titanium dioxide photocatalytic bactericides have advantages such as high sterilization efficiency, no drug resistance, and broad-spectrum antibacterial activity.

All-Round Antiviral Ecological Waterborne Paint

Photocatalyst is actually a nano-scale metal oxide material; titanium dioxide is used in coating products, which has strong oxidizing capability.

When this photocatalyst is added to coatings as an antibacterial agent, it generates a large number of highly chemically active free radicals through photocatalysis, which can trigger oxidation reactions of organic substances in various microorganisms.

Thus, it inhibits and inactivates microorganisms, mold, bacteria, etc., that come into contact with the paint film.
