Description

2-Propenoic Acid, 2-Methyl-, Polymer With Butyl 2-Propenoate, 2-Methylaziridine And 2-Methyl-2-[(1-Oxo-2-Propenyl) Amino]-1-Propanesulfonic Acid Monosodium Salt CAS NO 125275-84-5 is a specialized, high-performance copolymer designed for demanding industrial applications. This product matters because it combines the properties of acrylic, butyl acrylate, and a sulfonic acid functional monomer to deliver exceptional performance as a dispersant, stabilizer, and rheology modifier. It is primarily needed by manufacturers in the coatings, adhesives, and construction chemical industries where superior water resistance, stability, and flow control are critical.

Application

• Architectural and Industrial Coatings: Acts as a highly effective dispersant and stabilizer for pigments and fillers, improving color development and preventing settling.
• Adhesives and Sealants: Functions as a rheology modifier to control viscosity and sag resistance, while enhancing adhesion to various substrates.
• Construction Chemicals: Used in cementitious systems, tile adhesives, and grouts to improve workability, water retention, and final mechanical strength.
• Paper Coatings: Serves as a retention aid and dispersant to ensure uniform coating quality and improved printability.
• Textile Processing: Employed as a leveling agent and dye dispersant to achieve even color application and fastness.
• Personal Care Products: Can be utilized in hair styling gels and creams as a film-forming agent and stabilizer.

Quality Control

Our production of this advanced copolymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Each lot undergoes rigorous testing for key parameters including solid content, viscosity, pH, and ionic character. A comprehensive Certificate of Analysis (COA) documenting these results 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 temperatures between 15°C and 25°C (59°F and 77°F). This product is hygroscopic (moisture-sensitive). Keep away from strong oxidizing agents and extreme heat to prevent degradation of the polymer.
