Quaternary Ammonium Compounds

Biofilm control is critical in certain applications such as those found in the papermaking industry and cooling water systems. The long-desired product is one that provides enhanced biofilm control through the stabilization of the active ingredient, providing fast-kill to planktonic bacteria, reduced corrosion and is a product that is easy-to-use.

Bardac™ LF 18-50 WT

A cost-effective way to manage the algae growth found in systems as well as to clean the systems. The Bardac™ LF 18-50 WT product is synergistic with oxidizing biocides and prevents algae growth, lowering the need for halogens. Bardac™ LF 18-50 WT also improves the performance of scale and corrosion inhibitors. It is also synergistic with stabilized oxidizing biocides, as it acts as a complementary algaecide in multifunctional formulated products due to its compatibility with anionic compounds such as scale dispersants.

Bardac™ LF 18-50 WT is water soluble and is a product solution that is not a dermal sensitizer. Its low-foaming tendency compared to other regular ADBAC-based products makes it easier to use in recirculating systems such as cooling towers and decorative fountains.  

  • Application: Industrial
  • To be dosed via a dosing pump
  • Product packaging size: available in drums and IBC’s

Carboshield™ 1000E

The Carboshield™ 1000E product is comprised of a blend of didecyl dimethyl ammonium carbonate and didecyl dimethyl ammonium bicarbonate. Unlike traditional chloride quaternaries, this non-chloride QAC provides excellent corrosion inhibition properties on steel, aluminum, iron, brass and copper. 

It can be used as a cationic surfactant, a thin film forming corrosion inhibitor or a wetting/dispersion agent. It is hard-water tolerant and requires little or no additional sequestering agents for effective performance. The Carboshield™ 1000E product is compatible with numerous nonionic surfactants as well as many dyes and fragrances.  

  • Application: Industrial
  • To be dosed via dosing pumps  
  • Forms a film on metal surfaces as a protective barrier, helping to reduce pitting corrosion
  • Can be formulated with oxygen scavengers where it requires a neutral to slightly basic formulation (buffer)
  • Non-corrosive chemical as there is no typical chloride pitting like traditional quaternary amines
  • Water miscible and can be emulsified in oil
  • Amenable to aqueous (freshwater and seawater) and non-aqueous systems
  • Exhibits effective inhibition properties for steel, aluminum, iron, brass and copper
  • Can be used in the oil and gas industry
  • Product packaging sizes: available in drums or IBC’s

Uniquat™ 2280

The Uniquat™ 2280 product shows a broad spectrum of activity against both gram-positive and gram-negative bacteria and is also effective on fungi and viruses, including those that are enveloped. Showing a high tolerance to hard water (above 350ppm), it remains active in the presence of heavy organic soiling. Its impressive surfactant and wetting properties make it one of the multipurpose biocides of choice for cooling systems and swimming pool water treatment as part of formulations.

This Uniquat™ 2280 product displays synergistic effects in combination with aldehydes and complexing agents, such as EDTA, but is incompatible with anionic detergents. It is registered in a large number of countries for numerous applications, including water treatment applications as well as hygiene and material protection applications.

Please check local regulations or consult your Lonza representative for further information.

  • Application: Industrial
  • To be dosed via dosing pumps
  • Contains 50% solution of Dialkyl Dimethyl Ammonium Chloride (DDAC)
  • Shows a high tolerance to hard water (above 350ppm)
  • Product packaging size: available in drums, IBC’s and bulk
