Key Properties

Twin-chain structure with higher efficacy than single-chain quaternaries
Extremely low foaming — suited to spray and high-flow systems
Little interference from organic load or hard water
Alternating with oxidizers helps delay resistance development

Applications

Biocide and algicide for cooling water and spray systems
Preservation of paper, coatings and adhesive systems
Oilfield injection water and wastewater bacterial control
Synergistic component in biocide blends
