Description

Poly(Oxy-1,2-Ethanediyl), .Alpha.-Phosphono-.Omega.-Butoxy- is a specialized organophosphorus surfactant and functional polymer additive. This compound is valued for its unique combination of hydrophilic polyether chains and a phosphonate functional group, offering excellent surface activity, chelation, and dispersion properties. It is primarily used by formulators and process engineers in industries such as water treatment, textile processing, and specialty coatings where controlled surface modification and scale inhibition are critical.

Application

• As a scale and corrosion inhibitor in industrial cooling water and boiler water treatment systems.
• As a dispersing agent and grinding aid for inorganic pigments and fillers in coating and ceramic formulations.
• As a surfactant and wetting agent in textile auxiliaries for dyeing and finishing processes.
• As a chelating agent for metal ions in detergent formulations and cleaning products.
• As a functional monomer or additive in the synthesis of specialty polymers requiring phosphonate groups.
• In oilfield chemicals for scale control in production and water injection wells.
• For paper processing as a dispersant and deposit control agent.
