Efficient pulp, paper and mineral slurry operations require effective slime control. Microbial Control solutions help control slime-forming bacteria that cause offensive odors, equipment corrosion and even spots and breaks in paper. Our solutions can also help protect your coatings, mineral slurries, latexes, starch solutions and other pigments and binders from microbial contamination to help increase operation efficiency and minimize downtime.

Our portfolio of microbial solutions protect the range of processes and applications vulnerable to microbes—offering fast, effective and functional contamination control of slime and mold.
