Prevent microorganism from forming on different surfaces

The demand for antimicrobial coating is ever increasing especially on the sector of health care where antimicrobial environment is a must! The coatings also contribute to cleaner inside air and reduce allergic reactions. The purpose of antimicrobial coatings is to prevent microorganism from forming on different surfaces. Therefore, it is no surprise that the largest industry using such coatings is the health care industry. For example clinics and elderly care use antimicrobial coatings to protect patients and employees from microorganisms which may cause infections and other health problems.

These coatings are applicable also in hospitals and other clinics to sterilise equipment to keep it clean and free from germs. The antimicrobial coatings market is more extensive than one might assume. Besides health care, the coatings appear in other industries including factories and construction, catering and food processing, schools and laboratories as well as home and leisure.

The anti-microbial coatings appear as hygiene coating in the food processing and catering industries, as antibacterial systems in schools and labs as well as anti fungal solutions for example in bathrooms.

Protect and prevent medical devices

The healthcare sector uses the most antimicrobial coatings. They contribute to improving patient health and reducing the risk of spreading contagious infections. Therefore, applying the coatings on medical equipment and devices reduces the risk even further; more and more medical coatings with antimicrobial properties reach the market. Consequently,  manufacturers are looking for antimicrobial coatings that are biocompatible, biostable and non-toxic.

Antimicrobial medical device coatings utilise polymers infused with antimicrobial minerals that can be applied on everything from catheters to medical electronics.

The antimicrobial coatings for medical devices market can be divided by type of material into:

  • Metallic coatings: silver, copper and other metallic coatings.

    Antimicrobial coatings are suitable when absolute hygiene is a must.

  • Non-metallic coatings: polymeric and organic coatings.

The coatings can also be divided into categories by device type:

  • Catheter
  • Implantable devices
  • Surgical instruments
  • Others (mandrels & molds, guidewires, epidural needles, and elastomeric seals).

Special duct work coatings with antimicrobial proporties

One of the fastest growing problems in the UK is poor indoor air quality which results in allergies, asthma and other discomforts. Not to mention “mould-related” problems which lead to dropping of the indoor air quality. The mould problems occur when mold, bacteria, and fungi entre our buildings through air duct intakes, or multiply in the ducts themselves. These microorganisms put out spores that grow wherever they have access to dust, dirt, and the minerals found in moisture. Fortunately, the indoor air quality improves by cleaning the duct work. Maintaining the cleanliness is the job of antimicrobial coatings.

Improve indoor air quality with antimicrobial duct coatings

A way to prevent mould and harmful microorganisms from growing is to treat the surfaces at risk with an antimicrobial coating on basis of silver or calcium hydroxide. Silver and calcium hydroxide are antimicrobial substances, and using one of these with an epoxy coating on the inside of ducts is effective in controlling the growth of bacteria, mould and fungi. At the same time, the inside air quality also improves. The coatings allow pressing, drawing bending, roll forming and otherwise fabricating the metal without loss of coating or efficacy.These epoxy coatings offer an added benefit of chemical corrosion resistance. Coated steel is more corrosion resistant and easier to clean; thus it requires less maintenance. However, an antimicrobial coating for ductwork is not a substitute for duct cleaning. Periodical cleaning the duct surface from dust and dirt is necessary even after coating.
