Mergal® 758

Mergal® 758 by Troy Corporation acts as a bactericide or fungicide. It is a formaldehyde-free, VOC-free, broad-spectrum in-can preservative. It is a pH-neutral, free-flowing dispersion product used to prevent deterioration caused by bacteria, fungi and yeast. Also helps to extend paint and stain shelf life. Mergal® 758 combines fast-acting properties with a long lasting protection. Used for waterborne coatings systems.

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.
