Antimicrobial Paint Additives

What are Antimicrobial Paint Additives?

Antimicrobial paint additives are an advanced controlled release antimicrobial treatment for coatings and paints. It can be introduced into a paint, coating, ink, or lacquer during manufacturing to make it resistant to bacteria and microbes.  

It can be formulated to suit the type of paint or coating, the material it may be used to treat, and the manufacturing process employed.

It can be efficiently and cost-effectively manufactured into all types of solvent, water-based, liquid, oil, or powder paints and coatings, including:

  • General industrial coatings
  • Decorative coatings
  • Specialty coatings
  • Specialty Inks
  • Varnishes

What are the Benefits of the Antimicrobial for Paints & Coatings?

Antimicrobial coating additives provide lasting and effective protection against harmful bacteria, mold, fungi, and viruses by up to 99.99%, ultimately helping your paint or coating to minimize staining, foul odors, and material degradation on any surface it is applied. Once infused into your paints or coatings, our controlled-release antimicrobial additive will not leech, cause discoloration or affect the final finish.

The Advantage: 

  1. It can be formulated into a concentrated powder or liquid suspension depending on the target material and manufacturing process.
  2. It is a colloidal suspension and, in this form, does not settle so it will mix better with your paints and coatings.
  3. As a colloidal particle, it will blend better as an additive, creating a more uniform distribution.

Antimicrobial Paint & Coatings Effectiveness 

Our controlled release antimicrobial is effective against gram-positive, gram-negative bacteria (including methicillin- and vancomycin-resistant bacteria), fungi, and viruses. 

With significantly higher potency, it requires lower antimicrobial dosages, a lower environmental footprint, and lower non-bacterial cellular interactions. The key features of our antimicrobial are:

  • An enormous increase in surface area results in more coverage with lesser particle amounts. Compared to micron-sized particles that are a 1000x increase in surface area coverage.
  • Faster, more efficient ion exchange due to the shorter distance the molecules have to travel;
  • Ability to penetrate and destroy bacteria from the inside out.
