Microban® Zinc Technologies: ZPTech®

ZPTech® zinc technology is a broad spectrum antimicrobial with proven efficacy against the growth of bacteria, mould, mildew. ZPTech® has multiple modes of action, making it harder for microbes to become resistant to its effects.

The Benefits of Zinc Antimicrobial Technologies

  • Low solubility: ZPTech® antimicrobial zinc technology offers a low solubility (8 ppm), making it a very durable antimicrobial
  • Durable: Durability testing shows that polymers soaked for 2000 hours at 70°C in a detergent bath containing 3000 ppm ZPTech® remained 99.99% effective in preventing the growth of Klebsiella pneumoniae, a Gram-negative bacteria associated with hospital-acquired infections
  • Thermally stable: The thermal stability of ZPTech® makes it suitable for use in a variety of manufacturing applications and materials used in moist, humid environments such as cleaning sponges, sealants, cement, polyolefin film liners, commercial cleaning trolleys, and paints & coatings
  • Works 24/7: ZPTech® technology is constantly active on the surface of treated products. It is incorporated throughout the material during the manufacturing process, ensuring it remains effective even if an object is nicked, scratched or abraded in use
  • Safe to use: Microban ZPTech® encapsulates zinc pyrithione in customized carriers, making it safe to handle while causing no disruption to current manufacturing processes

Antifungal Treatments for Mold Prevention

Microban® offers a variety of zinc antifungal technologies that are built-in to products such as artificial turf, caulks and sealants, paints and coatings, and cement. These targeted solution technologies are time tested and proven to offer superior mold prevention on surfaces.

When mold and mildew come in contact with product surfaces, Microban® zinc antifungal technology penetrates the cell wall of the microbe and disrupts key cell functions so that the microbe cannot function, grow or reproduce.

What is Fungus?

Early fossil records suggest that fungi have been on Earth for over a billion years, and some experts estimate that today over 1.5 million fungus species exist. Common fungi include mushrooms, puffballs, truffles, yeasts and most mildews.

Fungi are commonly referred to as mold and begin life as microscopic airborne spores that germinate on contact with the surface of a nonliving organic matter where moisture is present. Mold is then able to penetrate the organic material, secreting enzymes and absorbing water and the digested sugars and starches from the nutrient source.

Mold spores are present everywhere in our indoor and outdoor environment and many of the products found in our homes provide rich nutrient sources. The best defense against mold is prevention: control moisture in your home including high humidity levels and look for built-in antifungal product protection that can help prevent the growth of mold.

Fungal Laboratory Testing

Microban's fungal testing lab performs a wide range of industry standard test methods to validate antifungal efficacy. Samples can be evaluated utilizing nutrient challenge protocols or in the fungal chamber, which simulates environmental conditions using the AATCC Test Method 30, Part III.

All products engineered with Microban® antifungal protection undergo extensive testing in our microbiology and chemical analysis labs. In addition, Microban® technology has been proven effective in over 20,000 tests at over 27 independent laboratories around the world.

Using industry standard testing methods, the samples pictured demonstrate the effectiveness of Microban® zinc technology against mold that can cause stains, odors and product deterioration.
