CIT MIT overview
CIT/MIT controls bacteria, fungi, yeast and algae at very low concentration. 14% active is standard; 1.4% and 2.0% grades are available on request.
Used in cooling towers, paper and pulp, water-based paints and coatings, adhesives and latex emulsions, metalworking fluids, oilfield, wood preservation and building materials.
How CIT MIT works
Isothiazolinones react with thiol groups of microbial enzymes, rapidly stopping growth and metabolism and then killing the cells.
