Description

2-Propenoic Acid CAS NO 25302-81-2 is a versatile and reactive organic acid monomer, also widely known as acrylic acid. This compound serves as a fundamental building block in polymer chemistry, valued for its ability to introduce carboxylic acid functionality and enhance adhesion, cross-linking, and water solubility in final products. It is essential for manufacturers in the coatings, adhesives, textiles, and superabsorbent polymer industries seeking to develop high-performance materials.

Application

• Polymer Synthesis: Primary monomer for the production of polyacrylic acid (PAA), superabsorbent polymers (SAP), and acrylate copolymers.
• Coatings & Paints: Key raw material in water-based acrylic resins, providing excellent gloss, durability, and weather resistance for architectural and industrial coatings.
• Adhesives & Sealants: Used to formulate pressure-sensitive adhesives (PSAs) and construction sealants with strong bonding properties and flexibility.
• Textile & Leather Processing: Employed as a finishing agent to improve fabric hand feel, wrinkle resistance, and dyeability.
• Personal Care & Hygiene: Critical component in the manufacture of superabsorbent materials for diapers, feminine hygiene products, and adult incontinence products.
• Water Treatment: Acts as a scale inhibitor and dispersant in industrial water treatment formulations.
• Paper & Packaging: Used in coatings and sizing agents to enhance strength, printability, and water resistance of paper products.

Quality Control

Our 2-Propenoic Acid is manufactured under stringent quality management systems. Every batch undergoes rigorous analytical testing, including assay, purity, and impurity profile analysis, to ensure it meets exacting industry and customer specifications. Certificates of Analysis (COA) are provided with each shipment, documenting compliance with agreed parameters. We support compliance with global regulatory frameworks, including REACH.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials. Due to its properties as a strong acid/organic solvent and highly volatile nature, containers must be kept tightly sealed to prevent evaporation and moisture ingress. Recommended storage temperature is 15-25°C. Keep away from oxidizing agents, bases, and amines.
