Overview

Mergal® 758 is a high-performance, broad-spectrum wet-state preservative designed to provide outstanding protection against microbial contamination in water-based industrial formulations. Developed by Arxada (formerly Troy Corporation), this product is based on a synergistic blend of isothiazolinones, making it highly effective against bacteria, mold, and yeast. With its excellent pH stability and formaldehyde-free formulation, Mergal® 758 is widely used in paints, adhesives, emulsions, and other aqueous systems where long-term preservation is essential without compromising formulation compatibility or regulatory standards.

Benefits

• Broad-Spectrum Protection – Active against a wide range of bacteria, fungi, and yeast
