Acrylic acid-maleic anhydride copolymer

Acrylic acid-maleic anhydride copolymer (CAS 26677-99-6) is a synthetic polymer used across water treatment, construction, and industrial process chemistry. It functions as a scale inhibitor, dispersant, and corrosion inhibitor in systems where mineral deposits must be controlled.

In water treatment, it prevents calcium carbonate, calcium sulfate, and other mineral scales from forming on heat exchanger surfaces and cooling tower equipment. This ensures optimal thermal efficiency and prevents costly downtime in industrial cooling systems.

Textile and paper processing operations use it to sequester hardness ions and improve process water quality. This reduces interference with dyes and sizing agents, leading to more consistent product quality and reduced chemical waste during manufacturing.

In construction chemistry, it modifies the rheology of cementitious formulations, controlling workability and retarding premature stiffening. This allows for better handling of concrete and mortar in various environmental conditions and complex builds.

Metalworking and industrial lubricant formulations incorporate it as a corrosion inhibitor and dispersant. It keeps metal fines and contaminants suspended rather than depositing on equipment surfaces, extending the life of machinery and tools.

The copolymer is typically supplied as an aqueous solution, with active content concentrations commonly ranging from 40% to 50%. Technical grade is the standard commercial specification for industrial and water treatment applications.

Packaging is generally available in drums and IBC totes suited to bulk industrial procurement. These formats ensure safe transport and easy integration into automated dosing systems used in large-scale chemical processing facilities.
