Description

2-Propenoic Acid, Sodium Salt, Polymer With 2,2'-[1,2-Ethanediylbis(Oxymethylene)]Bis[Oxirane] is a high-performance, water-soluble polymer derived from sodium acrylate and a diepoxide crosslinker. This specialized copolymer is engineered to provide exceptional thickening, dispersing, and film-forming properties in aqueous systems. It is a critical raw material for formulators in the coatings, adhesives, construction chemicals, and personal care industries seeking to enhance product performance and stability.

Application

• Water-Based Coatings & Inks: Acts as a rheology modifier and thickener to control viscosity, improve sag resistance, and enhance application properties.
• Construction Chemicals: Used in cementitious formulations, tile adhesives, and grouts to improve water retention, workability, and adhesion.
• Adhesives & Sealants: Functions as a tackifier and stabilizer in aqueous adhesive systems, improving bond strength and open time.
• Personal Care & Cosmetics: Serves as a film-forming agent, emulsifier, and viscosity enhancer in hair styling gels, creams, and lotions.
• Textile & Paper Processing: Utilized as a sizing agent, coating binder, or processing aid to improve fiber strength and surface properties.
• Industrial Dispersants: Effective for stabilizing pigments, fillers, and other solid particles in suspension to prevent settling.

Quality Control

Every batch of our 2-Propenoic Acid, Sodium Salt, Polymer is manufactured under a strict quality management system. We perform rigorous in-process and final testing to ensure consistent purity, viscosity, solids content, and pH meet defined specifications. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with each shipment to guarantee traceability and compliance for 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 can affect product performance.
