Dequest®
Italmatch Chemicals offers unique specialty additives to meet the needs of the industries involved in water management or deal with processes or applications where water plays a crucial role. More than 50 years ago, the Dequest® brand pioneered the development of phosphonates-based scale inhibitors. Since then, DEQUEST® line have been the product of choice in various applications for many years. Today, we manufacture a broad range of water management additives including Dequest® phosphonates, Dequest® P acrylic / maleic based (co-)polymers, Dequest® PB biological polymers and tailor-made products for specific applications. Either individually or in combination, the essential properties of Dequest® products are:
- Threshold scale inhibition
- Sequestration/Chelation
- Dispersion/Deflocculation
- Corrosion control
Due to their wide range of functional properties Dequest® products have been used in many applications in numerous water-related industries, including:
- Cement modification
- Ceramics
- Cleaning (Acid Cleaners, Boiler Cleaning, Bottle washing compounds, Dairy cleaners, Household detergents and cleaners, Industrial & Institutional cleaners, Vehicle wash)
- Cosmetics/Shampoos
- Desalination
- Electroplating
- Geothermal water treatment
- Hypochlorite bleach stabilization
- Industrial Water Treatment (Cooling water treatment, Boiler water treatment
- Metal cleaners and finishing
- Mining
- Peroxide bleach stabilization
- Pigment dispersion
- Paper recycling and Pulp & paper bleaching
- Scale removal
- Swimming pools
- Textile applications
Dequest® line is also used for Oil and Gas applications. After pioneering phosphonate antiscalant technologies, the product line has evolved to meet the industry’s growing demands with advanced acrylic/maleic copolymers, and biodegradable polymers under the Dequest® P label; a new generation of sustainable amino-acid phosphonates and a suite of ready-to-use solutions tailored to specific needs, under the Dequest® FS label. Dequest® additives prevent inorganic scale while delivering non-filming corrosion inhibition and dispersion in harsh downhole environments.
