Description

2-Propenoic Acid, 2-Methyl-, Polymer With 2-Methyl-2-(1-Oxo-2-Propenyl)Amino-1-Propanesulfonic Acid is a high-performance, water-soluble copolymer designed for demanding industrial applications. This specialized polymer combines the properties of methacrylic acid with a sulfonic acid functional group, offering exceptional dispersancy, scale inhibition, and compatibility in aqueous systems. It is a critical additive for industries requiring robust performance under challenging conditions, such as water treatment, construction, and textile processing.

Application

• Water Treatment: Acts as a highly effective dispersant and antiscalant for cooling water, boiler water, and reverse osmosis systems, preventing the deposition of calcium carbonate, sulfate, and phosphate scales.
• Construction Chemicals: Used as a superplasticizer and grinding aid in cement and concrete admixtures to improve workability, reduce water content, and enhance final strength.
• Detergents & Cleaners: Functions as a builder and anti-redeposition agent in industrial and institutional cleaning formulations, improving soil suspension and detergent efficiency.
• Textile Processing: Serves as a dispersing agent for dyes and pigments, ensuring uniform color application and preventing agglomeration in dye baths.
• Paints & Coatings: Employed as a pigment dispersant and stabilizer in water-based formulations, improving color development, gloss, and long-term shelf stability.
• Oilfield Chemicals: Utilized in drilling muds and completion fluids as a rheology modifier and fluid loss control agent to maintain wellbore stability.
• Paper & Pulp Industry: Acts as a retention aid and dispersant to improve paper quality, drainage, and the efficiency of filler and fiber retention.
• Personal Care: Can be used in hair care and skincare products as a film-forming agent and viscosity modifier, providing conditioning and sensory benefits.

Quality Control

Our production of this copolymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Each lot is characterized for critical parameters including solid content, viscosity, pH, and residual monomer levels. A comprehensive Certificate of Analysis (COA) detailing these specifications is provided with every shipment to support your quality assurance protocols.

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). 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.
