There’s no question that the advent of water-based paints and coatings brought its fair share of challenges. For formulators looking to offer new and innovative products for their customers, approximating the performance of solvent-based coatings in low-VOC, water-based alternatives can be a constantly moving target — there’s no shortage of microbial foes standing in the way, from bacteria and yeast, to mold and algae.
Global regulations add yet another layer of complexity. Waterborne solutions are now a permanent fixture in the paints and coatings industry, but many of the most effective preservatives in that arena — including formaldehyde releasers — face stringent dosage limitations for consumer markets, especially in Europe.
