JSYA-DDAC DDAC Biocide is didecyldimethylammonium chloride quaternary ammonium biocide with CAS 7173-51-5. This dual-purpose biocide is optimized for cooling tower circulating water and wood preservation. For cooling tower systems, it suppresses bacteria, algae and slime formation, preventing blockage and biological fouling inside pipelines and packing. For wood treatment, it penetrates timber to inhibit rot fungi and mildew, protecting lumber from decay and discoloration in outdoor humid enviro

Product Detail

Product Details

JSYA-DDAC is colorless to pale yellow transparent liquid. As a cationic quaternary ammonium compound, it attaches to microbial cell walls, disrupts cell membranes and causes microbial inactivation. It has low corrosion to carbon steel and metal cooling tower components. It can be continuously or intermittently dosed into cooling water, or diluted for wood dipping and vacuum pressure impregnation treatment.

Main advantages:

Broad-spectrum control of bacteria, algae and slime for cooling tower circuits
Dual function: cooling tower biocide plus wood rot & mildew preservative
Low corrosion to metal equipment and pipeline
Good penetration into wood substrate for long-term timber protection
Simple dilution and dosing, convenient for water and wood treatment
REACH / TSCA compliant for overseas export

Typical applications:

Cooling tower circulating water sterilization and algae control
Industrial open recirculating water system biocide
Sawn timber, lumber, wood log anti-rot and anti-mildew treatment
Wooden construction materials, outdoor wood components preservation
Wood processing plant fungicide for raw lumber

JSYA-DDAC DDAC biocide is a cost-effective quaternary ammonium biocide. It solves biological slime issues in cooling tower water systems and delivers fungal protection for outdoor timber, widely used in water treatment and wood processing industries.
