Product Overview

2-Ethylhexyl Acrylate, commonly known as 2-EHA, is a clear, colorless to pale yellow liquid ester derived from acrylic acid and 2-ethylhexanol. It serves as a reactive monomer in free-radical polymerization, contributing low glass transition temperatures (Tg) for soft, elastic polymers. With its branched alkyl chain, 2-EHA imparts hydrophobicity, improved weather resistance, and enhanced flexibility to final formulations.

Ideal for industries requiring robust, long-lasting materials, 2-EHA is widely used in the production of acrylic resins and copolymers. Its low volatility and high boiling point make it a stable choice for demanding processing conditions.

Key Features and Benefits

  • High Purity: Minimized impurities for cleaner polymerization and reduced side reactions.
  • Excellent Flexibility: Lowers Tg of polymers, enabling soft-touch and elastic properties.
  • Superior Adhesion: Enhances tackiness and bonding strength in adhesives and sealants.
  • UV and Weather Resistance: Branched structure provides durability against environmental degradation.
  • Low Odor: Suitable for sensitive applications like textiles and personal care products.
  • Versatile Reactivity: Compatible with styrene, vinyl acetate, and other co-monomers for custom formulations.

Applications

2-Ethylhexyl Acrylate excels in a variety of sectors, offering tailored solutions for performance-driven needs:

  • Adhesives and Sealants: Pressure-sensitive tapes, labels, and hot-melt adhesives for strong, removable bonds.
  • Coatings and Paints: Architectural, automotive, and industrial coatings for flexible, crack-resistant finishes.
  • Textiles and Nonwovens: Binders for fabrics, enhancing softness and durability in apparel and hygiene products.
  • Printing Inks: Flexible inks for packaging and graphics, ensuring vibrant, long-lasting prints.
  • Plastics and Resins: Copolymers for impact-resistant plastics and elastomers in automotive and construction.
  • Personal Care: Thickening agents and film-formers in cosmetics and hair care formulations.

By incorporating 2-EHA, manufacturers achieve products that balance flexibility, strength, and environmental resilience.

Safety and Handling Guidelines

Prioritize safety when working with 2-Ethylhexyl Acrylate to ensure compliance and protect personnel:

  • Hazards: Flammable liquid (Category 4); causes skin and eye irritation; may cause allergic skin reactions; harmful to aquatic life with long-lasting effects.
  • Personal Protective Equipment (PPE): Wear chemical-resistant gloves, safety goggles, and protective clothing. Use in well-ventilated areas or with respiratory protection if vapors exceed exposure limits.
  • Handling: Store in cool, dry, well-ventilated areas away from ignition sources, oxidizers, and strong acids/bases. Keep containers tightly sealed.
  • Spill Response: Absorb with inert material; ventilate area; avoid drains to prevent environmental release.
  • First Aid: Skin contact – wash with soap and water; Eye contact – rinse with water for 15 minutes; Inhalation – move to fresh air.
  • Environmental Considerations: Dispose of in accordance with local regulations; do not release into waterways.

Frequently Asked Questions (FAQs)

What is 2-Ethylhexyl Acrylate used for?

2-EHA is primarily used as a monomer in the synthesis of acrylic polymers and copolymers. It imparts flexibility and adhesion in applications like adhesives, coatings, inks, and textiles, making it ideal for products requiring elasticity and durability.

Is 2-Ethylhexyl Acrylate safe to handle?

While 2-EHA is flammable and can irritate skin or eyes, it can be safely handled with proper PPE, ventilation, and storage protocols. It’s stabilized with inhibitors like MEHQ to prevent unintended polymerization. Always consult the SDS for site-specific guidance.

What are the storage requirements for 2-EHA?

Store in stainless steel or lined tanks at temperatures below 25°C, away from light and heat. It remains stable for up to 12 months when kept under nitrogen blanket if needed. Avoid contamination with peroxides or metals.

Does 2-Ethylhexyl Acrylate meet regulatory standards?

Yes, our 2-EHA complies with major global regulations including REACH (EU), TSCA (USA), and EINECS. It’s free from restricted substances and available with full documentation for compliance verification.

Can 2-EHA be customized for specific formulations?

Absolutely. We offer tailored inhibitor levels, purity grades, and co-monomer compatibility testing. Contact our technical experts to discuss blending or application-specific modifications.

What is the shelf life of your 2-Ethylhexyl Acrylate?

Under recommended storage conditions (cool, dark, inert atmosphere), 2-EHA has a shelf life of 12 months. Regular quality checks ensure optimal performance beyond this period if unopened.

How does 2-EHA compare to other acrylic monomers like butyl acrylate?

2-EHA provides lower Tg (-50°C vs. -54°C for butyl acrylate) and better hydrophobicity due to its branched chain, making it superior for outdoor and flexible applications. However, it has slightly higher viscosity.
