Antimicrobials for paint and coatings preservation

Microorganisms are everywhere. In nature, they exist as part of the natural order of life, but in industry, bacteria, yeast, algae and fungi can cause significant damage.  Microorganisms require water and food to grow and a typical coating, emulsion or adhesive can provide the water and nutrients needed for bacteria and fungi to thrive.

Microbial spoilage is a serious issue if left untreated it can cause among others:

  • Reduced product performance
  • Discoloration and viscosity changes
  • Strong odors
  • Expensive product disposal costs

Microbial spoilage can be prevented by the effective use of antimicrobials or biocides.  Antimicrobials typically make up only a small percentage of formulation but they play a critical role in preventing microbial spoilage and contamination.
