Aqueous paint formulations require in-can preservation technologies to control contamination and increase shelf life. Our paint preservation technologies help fight against a wide spectrum of microbes, including bacteria and fungi (including both yeast and mold), to help prevent in-can contamination to deliver an excellent finished product that’s designed to last.

Our wide array of in-can preservatives offer cost-effective, long-term protection for a full range of architectural paint and coatings formulations.
