Microban Ceramics Antimicrobial Technologies

Ceramic products used in homes, health care facilities, industrial settings and other public places can attract stain, odor, and disease-causing bacteria due to moisture, heat and humidity. These microorganisms can put ceramic and porcelain bathroom fixtures, flooring tiles, glassware and other products at risk for damage, stains and degradation, as well as potentially cause illness in the people who use them.

Take bathrooms, a major hotspot for bacteria and other microorganisms. To quantify the risk, a team of Microban microbiologists measured levels of bacteria from public toilet surfaces in shopping centers, restaurants, gas stations and other retail outlets. On average, the toilet surfaces harbored 108 colony forming units (CFUs) per inch, with one toilet containing 2,256 CFUs per square inch. Flushing does not eliminate microorganisms in the bathroom; some adhere to the toilet surface where they begin to reproduce, while others become airborne via aerosols caused by the flush itself and can settle on other surfaces in the bathroom where they too begin to reproduce.[1]

Scrubbing with disinfectant cleaners is an essential way to temporarily reduce microbes on ceramic surfaces. However, because microbes reproduce so rapidly -- doubling in number every 20 minutes on unprotected surfaces -- the likelihood of microbial regrowth is very high and the effectiveness of cleaning is very short-lived.

Antimicrobials can provide ceramics products with continuous protection against microbes and extend the effectiveness of regular cleaning routines. The antimicrobial of choice must, however, be finely tuned to accommodate the complexity of ceramics production.

Microban Ceramics Antimicrobial Technologies

Producing ceramics is an extremely complex process. Ceramics are comprised of clay and other earthen elements mixed with a liquid, formed, dried and fired in a kiln at very high heat. The composition of the raw materials can vary considerably, even from lot to lot, as they are mined from the earth. In addition to variations within the natural minerals themselves, there are numerous process variables that can affect the finished ware, such as firing temperature and atmosphere. Interactions can occur between antimicrobial additive materials and accessory minerals in the glaze, often these interactions vary with firing temperature.

Any of these factors alone -- high heat, raw material variations or additives -- as well as the chemical interactions among them can produce surprising effects. Disruption to the delicate balance among the various components can damage, flux, spot, melt or otherwise render useless the ceramic product and its features. It takes extraordinary knowledge, skill and flexibility to consider all of these factors and produce a ceramic product that is not only functionally and aesthetically pleasing but also protected against microbial growth. This is exactly what Microban brings to ceramics manufacturers.

Microban’s patented ceramic antimicrobial technologies combat the uncontrolled growth of microbes with unique compounds that are carefully customized for each product’s manufacturing process and specifications. The antimicrobial is embedded within the ceramic coating and delivers continuous protection against microbes throughout the product’s lifetime, so long as the glaze remains intact.

Microban’s advanced technology, derived from natural components, enhances the durability and usefulness of ceramic products, including floor and wall tiles, sinks, toilets, bathtubs, showers, glassware and kitchen appliances, by stopping the growth of damaging, odor-causing bacteria.

In contrast to competitors’ ceramic antimicrobials, which require UV light or alter the ceramic surface to reduce microbes’ ability to adhere, Microban antimicrobials act directly against the microbe to prevent its reproduction and growth.

How It’s Implemented

Microban’s ceramics engineers work extremely closely with manufacturers to ensure that the antimicrobial technologies work seamlessly within existing manufacturing processes to enhance their products without impairing their aesthetics, function or durability.

Microban engineers’ unparalleled knowledge and experience with ceramics antimicrobials, its wide spectrum of antimicrobial technology, its novel testing and analytics capabilities, as well as the flexibility to make adjustments on the fly, are the reasons Microban antimicrobial technologies work so well.

The first step in implementing antimicrobial protection in a ceramic is a proof-of-concept trial in Microban’s labs. Microban engineers, in concert with its analytics lab, conduct numerous trials with the manufacturer’s actual raw materials and production specifications to determine which antimicrobial formulation works best. Engineers customize the formula, addition, and applications to work within the customer’s manufacturing requirements.

Once a formulation is tested and in place, another trial is conducted at the manufacturer’s site to ensure that local conditions, including water, kiln variations and other factors, don’t alter the antimicrobial’s efficacy. Even after commercialization begins, Microban engineers work with manufacturers to adapt the formulation to any minute changes that might alter the antimicrobial-embedded ceramic’s performance. With our understanding of ceramic processes and the properties of our antimicrobial additives that are necessary to impart the glaze with this property, we are able to customize solutions and overcome difficulties that can occur.

Microban is committed to delivering to its manufacturing partners a technical solution that is efficacious, as measured by ASTM E3031-15, transparent to their process and products, and economically feasible.  If the current Microban Antimicrobial Ceramics Formulations can’t meet these requirements, the Microban Ceramics engineers will develop a new formulation that will.
