S3 Surface Solutions uses an additive system that promotes a microbial-resistant environment. Available in two forms, Copper and Zinc, these additives are non-toxic and non-water-soluble, so they do not need moisture to activate and will stay active at all times. Competitive products use silver, which costs more, can have greater toxicity, and require moisture to activate.

Conventional microbial-resistant additives are applied to the surface of the host material and may wash away after repeated cleanings. S3’s microbial-resistant additives become part of the molecular structure, permanently dispersed in the material, so they are always present and always active.

 

Effectiveness

 
S3’s microbial-resistant additives have demonstrated functionality, in laboratory testing, for a reduction of Salmonella, E. coli, MRSA, Listeria and other bacteria in 2 hours at room temperature by 99.99999%, which is nearly as effective as boiling water. They are not a substitute for standard infection control practices, and users must continue to follow all current infection control practices, including those practices related to cleaning and disinfection of environmental surfaces. These microbial-resistant additives are currently undergoing testing to determine efficacy pending EPA registration under FIFRA.

Conventional antimicrobial systems typically are active within the first moments after they are applied to a surface, but the surface can become contaminated between cleanings. S3’s microbial-resistant additives remain effective between regularly scheduled cleanings.

The graph below illustrates the difference:

  • A conventional microbial-resistant system (red line) provides an initial quick clean, but then loses effectiveness until the next scheduled cleaning.
  • S3 epoxies with microbial-resistant additives (green line) begin to work on contact and continue to work throughout the life of the epoxy coating thereby providing a long-term active clean state.

Durability

 
When added to an S3 epoxy coating, our additives are engineered to disperse throughout the epoxy. As a result, floors and walls coated with these epoxies will continue to provide an active, microbial-resistant surface between scheduled cleanings, even if the epoxy surface gets scratched or abraded.

The graph below illustrates that the conventional cleaner (red line) requires three applications to produce a similar level of microbial resistance as an S3 surface with microbial-resistant additives (green line). These surfaces may reduce the labor required to maintain clean environments between regularly scheduled cleanings.

Summary

 
S3 microbial-resistant additives, when included in S3 epoxy coatings, are always present, cannot be removed, always active, and, when properly cleaned, can reduce microbes on surfaces by 99.99999%.  As such, they can reduce the total cost of ownership while providing a cleaner environment.
