Description

2-Methylbutyl Acrylate is a versatile acrylate ester monomer valued for its ability to impart flexibility, low-temperature properties, and enhanced adhesion in polymer formulations. Its branched alkyl chain structure makes it a key intermediate for producing specialty polymers with tailored performance characteristics. This product is essential for manufacturers in the coatings, adhesives, and specialty plastics industries seeking to modify the physical properties of their end products.

Application

• Acrylic Polymer and Resin Production: A key monomer for synthesizing copolymers used in pressure-sensitive adhesives, textile finishes, and leather coatings.
• Coatings and Paints: Imparts excellent flexibility, weatherability, and adhesion in automotive, industrial, and architectural coating formulations.
• Adhesive Formulations: Used to develop adhesives with improved low-temperature performance and tack for tapes and labels.
• Specialty Plastics and Elastomers: Serves as a comonomer to modify the glass transition temperature (Tg) and impact resistance of plastics.
• UV-Curable Systems: A reactive diluent and crosslinking agent in inks, coatings, and 3D printing resins that cure under ultraviolet light.
• Fiber and Textile Treatment: Employed in the production of binders and finishing agents to enhance fabric durability and handle.

Quality Control

Our 2-Methylbutyl Acrylate is produced under a stringent quality management system to ensure batch-to-batch consistency and high purity. Each lot is tested against rigorous internal specifications, which typically include assay, purity by gas chromatography, and control of key impurities like inhibitors and moisture. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials such as strong oxidizers, acids, and bases. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F). The product typically contains an inhibitor (e.g., MEHQ) to prevent polymerization during storage; monitor inhibitor levels for long-term storage.
