Redefining Antimicrobial Paints and Coatings

contact a member of our team to learn more

Whether in our personal homes or public spaces, high-touch surfaces can often suffer under the burden of immense microbial loads. Unwanted bacteria are constantly landing on surfaces and can double every 20 minutes, posing a cleaning problem that regular disinfection practices can’t keep up with. Further, the proliferation of microbes on surfaces and textiles can lead to degradation, stains and odors that decrease the value and usable lifetime of products.

Addressing the growing awareness and concern surrounding these issues, the antimicrobial coatings market has seen significant growth over the past five years and is expected to reach USD 21.5 billion by 2028.

What are antimicrobial coatings?

Antimicrobial coatings are surface treatments that contain antimicrobial additives to prevent the growth of bacteria, mold, and mildew. These include water-based, solvent-based, high solids and powder coatings – all specifically designed to add the value of protection and inherent cleanliness to products.

Antimicrobial paints and coatings have a wide range of end-use applications, but ultimately are used by manufacturers worldwide to optimize material preservation, enhance longevity of product use and provide lower maintenance solutions that complement regular cleaning practices. Common product applications across the industry include medical devices, air conditioning and ventilation systems, sanitary facilities and kitchens, inks, high touch surfaces, food processing, packaging, textiles and construction.

Antimicrobial coatings can be custom formulated for use in a variety of public spaces to protect high-touch surfaces 24/7.

How do antimicrobial additives in coatings work?

Coatings developed with Microban® antimicrobial technology contain a chemistry that works at the cellular level to continually disrupt the life functions of bacteria including eating, reproducing, and making waste. The moment microbes land on a coated surface, Microban technologies use a multi-modal attack to damage their protein, cell membrane, DNA, and internal systems, causing them to die.

Finished products enhanced with antimicrobial coatings experience a continuous reduction in the presence of stain and odor causing bacteria 24/7 for the usable lifetime of the product. The ‘always-on’ technology keeps surfaces cleaner in between cleanings and supports a systems approach to managing the unwanted microbial load even after multiple touches.

These coatings are versatile in application and can be integrated further down the manufacturing pipeline, ultimately making them less intrusive to existing production processes. Microban works with manufacturers to identify additive solutions specific to each product application, not only to develop a high-performing antimicrobial solution, but to preserve the desired look and feel of the finished product or surface.

How to create an antimicrobial coating

Antimicrobial paints and coatings are an ideal choice for a wide variety of finished products across multiple industries. Ensuring the result has desired efficacy and value, manufacturers must carefully navigate through key considerations:

Nature of risks – consider end use environment and conditions of finished product such as light exposure, cleaning practices, abrasiveness in use, expectant product life, humidity etc.

Application methods – consider current manufacturing processes and select the optimal choice for the finished product

roll to roll | dip coating | spray coating | padding | removable films | powder coating | UV cured | 2-part epoxy | sputtering

End goals & performance needs – consider purpose of coating additive: protection from premature degradation, organism-specific targeting, or both, as well as desired efficacy, regulatory compliance needs, and material properties

Key benefits of Microban® antimicrobial additives for paints and coatings

  • Seamless integration of antimicrobial additive incorporated during manufacturing without disrupting existing processes or desired look and feel of finished product.
  • 24/7 protection against bacteria, mold and mildew growth – keeping finished products fresher, cleaner and more durable
  • Enhanced product differentiation that provides end-users greater peace of mind
  • Detailed formulations compliant with global regulations
  • Organism targeting by industry to ensure coating provides maximum value and effectiveness to end-use environment
  • Complements existing cleaning practices and does not wash off or wear away
  • Cost-effective and streamlined approach based on experiences with test methods, existing applications and proven efficacy
  • Perfect for addition to coatings used in hot and humid environments, such as bathrooms and kitchens
