Description

n-Butyl Acrylate CAS NO 141-32-2 is a clear, colorless liquid monomer belonging to the acrylate ester family. It is a crucial building block in polymer chemistry, valued for its ability to impart flexibility, water resistance, and weatherability to a wide range of copolymers. This high-purity monomer is essential for manufacturers in the coatings, adhesives, textiles, and plastics industries seeking to enhance product performance.

Application

• Acrylic Polymer Production: A key comonomer for synthesizing acrylic resins used in water-based paints, industrial coatings, and architectural finishes.
• Pressure-Sensitive Adhesives (PSAs): Imparts essential tack and peel adhesion properties to adhesive tapes, labels, and films.
• Textile and Leather Finishing: Used in polymer emulsions for fabric coatings, non-woven binders, and leather finishing agents to improve durability and handle.
• Plastic Modifiers: Serves as a impact modifier and processing aid in plastics to enhance flexibility and low-temperature performance.
• Paper Coatings: Component in coatings that provide gloss, printability, and water resistance to paper and paperboard.
• Sealants and Caulks: Contributes to the elasticity and adhesion of acrylic-based sealants used in construction.

Quality Control

Our n-Butyl Acrylate is manufactured under stringent quality management systems. Every batch undergoes comprehensive analytical testing, including gas chromatography (GC) for purity and assay, to ensure it meets exacting specifications for monomer content and low inhibitor levels. Certificates of Analysis (COA) are provided with each shipment, documenting compliance with agreed parameters. We support global supply chains with relevant regulatory documentation.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat, sparks, and open flame. Due to its properties of being easily oxidized (store under inert atmosphere) and highly volatile, the product should be kept under a nitrogen blanket when in storage for extended periods and handled with appropriate precautions to prevent polymerization. Recommended storage temperature is 15-25°C. Keep away from strong oxidizing agents, acids, and bases.
