For every problem there are solutions. And, for every solution, challenges may arise. As paint and coatings formulators have become increasingly adept at matching the desirable performance characteristics of solvent-based coatings with environmentally preferred, low-VOC, water-based products, they also face microbial growth and contamination challenges.
It’s a well-known premise in the industry: wherever there is water, there are “bugs” - tiny microorganisms capable of contaminating paints, coatings manufacturing facilities and key raw materials. Chemical preservatives, or biocides, are required to control and kill these microorganisms, both in the plant and in the can, to ensure paint and coatings formulations perform optimally. Today, barriers and regulatory limitations placed on the use of industry preservatives have limited the solutions available in our toolbox.
