Description

2-Propenoic acid, butyl ester, polymer with ethenylbenzene, 2-methyl-2-[(1-oxo-2-propenyl) amino]-1-propanesulfonic acid, 2-methyl-2-[(1-oxo-2-propenyl) amino]-1-propanesulfonic acid monosodium salt and 2-methyl-2-propenamide is a high-performance, water-soluble copolymer engineered for demanding industrial applications. This specialized polymer is valued for its exceptional dispersing, scale inhibition, and water retention properties, making it a critical additive in processes requiring superior control over mineral salts and particulates. It is primarily utilized by industries such as water treatment, construction, textiles, and coatings, where reliable performance under challenging conditions is non-negotiable.

Application

• Industrial Water Treatment: As a highly effective dispersant and antiscalant in cooling water, boiler water, and reverse osmosis systems to control calcium carbonate, sulfate, and phosphate scales.
• Construction Materials: As a superplasticizer and water-reducing agent in high-performance concrete and cement formulations to improve workability and final strength.
• Textile & Dyeing Auxiliary: As a dispersing agent for pigments and dyes, ensuring uniform color and preventing agglomeration during processing.
• Paper & Pulp Production: As a retention aid and dispersant to improve fiber retention, sheet formation, and process efficiency.
• Coatings & Paints: As a pigment grinding aid and stabilizer in aqueous coating systems to prevent settling and ensure consistent viscosity.
• Oilfield Chemicals: As a component in drilling muds and scale inhibitor formulations for downhole mineral control.
• Detergent & Cleaning Formulations: As a builder and dispersant to enhance the performance of industrial and institutional cleaning products.

Quality Control

Our production of this advanced copolymer adheres to strict quality management systems, ensuring batch-to-batch consistency and performance reliability. Each lot is tested against key parameters including solid content, viscosity, pH, and functional group activity. A comprehensive Certificate of Analysis (COA) detailing these specifications is provided with every shipment. We support our global clients with documentation for relevant regulatory frameworks, including REACH compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C/59-77°F). This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent moisture absorption, which may affect product performance. Keep away from incompatible materials such as strong oxidizing agents.
