Description

2-Ethylhexyl Acrylate (CAS NO 103-11-7) is a high-purity, monofunctional acrylate ester monomer essential for producing polymers with exceptional flexibility, low-temperature performance, and UV resistance. Its primary value lies in its ability to impart outstanding durability, adhesion, and weatherability to a wide range of industrial coatings, adhesives, and sealants. This product is a critical raw material for manufacturers in the paints & coatings, pressure-sensitive adhesives, textile, and plastics industries seeking to enhance product performance and longevity.

Application

• Pressure-Sensitive Adhesives (PSAs): A key component for acrylic-based PSAs used in tapes, labels, and graphic films, providing excellent tack and peel adhesion.
• Coatings & Paints: Used as a co-monomer in acrylic resins for architectural, industrial, and automotive coatings to improve flexibility, gloss, and resistance to weathering and hydrolysis.
• Textile & Leather Finishing: Employed in polymer emulsions for fabric coatings and leather finishes to enhance softness, water repellency, and durability.
• Plastic Modifiers: Acts as an impact modifier and processing aid for engineering plastics, improving toughness and low-temperature properties.
• Sealants & Caulks: Incorporated into formulations to ensure long-term elasticity, adhesion, and resistance to environmental degradation.
• UV-Curable Systems: Serves as a reactive diluent and crosslinker in inks, coatings, and 3D printing resins cured by ultraviolet light.

Quality Control

Our 2-Ethylhexyl Acrylate is manufactured under a stringent quality management system to ensure batch-to-batch consistency and high purity. Every lot is tested against rigorous internal specifications, which typically include assay, color, acidity, moisture content, and inhibitor level analysis. A Certificate of Analysis (COA) documenting these results is provided with each shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat, sparks, and open flame. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F). This product is easily oxidized (store under inert atmosphere) and is light-sensitive. Keep away from strong oxidizing agents, acids, and bases. Always check the inhibitor type and level before extended storage.
