2-Ethylhexyl Acrylate (2-EHA): The Essential Monomer for Adhesives & Coatings – Buying Guide

CAS No.: 103-11-7 | Synonyms: 2-Ethylhexyl 2-propenoate, Octyl Acrylate, Isooctyl Acrylate

If you’re sourcing high-performance acrylic monomers for pressure-sensitive adhesives, architectural coatings, sealants, or polymer modification, you’ve likely searched for 2-Ethylhexyl Acrylate (2-EHA). As one of the most widely used soft monomers in the acrylic industry, 2-EHA delivers unmatched flexibility, low-temperature toughness, and adhesion—making it irreplaceable for manufacturers worldwide.

In this guide, we break down everything global importers need to know: key properties, industrial applications, quality specifications, packaging, storage, and critical buying tips to secure reliable supply at competitive prices.

What Makes 2-Ethylhexyl Acrylate (2-EHA) Indispensable?

2-EHA is a clear, colorless liquid monomer with a long branched alkyl chain, which gives it unique performance advantages:

• Low glass transition temperature (Tg ≈ -65°C) for exceptional low-temperature flexibility

• Excellent tack, peel strength, and shear resistance for pressure-sensitive adhesives (PSA)

• Outstanding water resistance, UV stability, and weatherability for exterior coatings

• Good compatibility with MMA, BA, St, VA, and other acrylic & vinyl monomers

• Low volatility and high boiling point (~215°C) for stable processing

• Stabilized with MEHQ (monomethyl ether hydroquinone) to prevent premature polymerization

These properties explain why 2-EHA is the first-choice soft monomer for adhesive and coating formulators across North America, Europe, Southeast Asia, and the Middle East.

Core Industrial Applications of 2-EHA

1. Pressure-Sensitive Adhesives (PSA) – Largest End Use

2-EHA is the foundation monomer for acrylic tapes, labels, protective films, medical adhesives, and sticky notes. It provides:

• Initial tack (instant stick)

• Long-term bonding strength

• Flexibility on curved & irregular surfacesLeading adhesive brands including Henkel, 3M, Avery Dennison, and H.B. Fuller rely on high-purity 2-EHA for consistent performance.

2. Paints & Coatings

Used in architectural latex coatings, industrial finishes, automotive coatings, and wood coatings:

• Improves film flexibility and crack resistance

• Boosts adhesion to metal, plastic, concrete, and wood

• Enhances durability and outdoor weatheringIt is widely used in elastic waterproof coatings and exterior wall coatings.

3. Sealants, Textiles & Leather Finishes

• Adds elasticity and water resistance to caulks and sealants

• Imparts softness, washability, and water repellency to textiles and leather

• Acts as a modifier for acrylic rubber and polymer emulsions

4. Polymer Modification & Plasticizers

Lowers Tg of hard polymers (PMMA, polystyrene) to improve toughness and processability.

Key Specifications for Global Import

When sourcing 2-EHA internationally, insist on these standard industrial-grade specs to ensure formulation consistency:

• Purity: ≥99.0% (GC) – industrial grade; ≥98.0% for general purpose

• Color (APHA): ≤10

• Acid Value: ≤0.01 mg KOH/g

• Water Content: ≤0.05%

• Stabilizer: MEHQ 50–200 ppm

• Molecular Formula: C₁₁H₂₀O₂

• Molecular Weight: 184.28

Packaging, Shipping & Storage – Critical for Importers

2-EHA is a Class 3 flammable liquid and requires compliant logistics:

• Standard Packaging: 180 kg steel drum, 900 kg IBC tank, bulk ISO tank

• Storage: Cool, dry, well-ventilated area; avoid direct sunlight, heat, oxidizers

• Handling: Prevent polymerization; keep containers tightly closed

• HS Code: 29161290 (for customs clearance reference)

Buying Guide for International Importers

To optimize cost, quality, and supply security:

1. Prioritize Purity: 99% grade ensures stable polymerization and consistent end-product performance.

2. Verify Stabilizer Content: MEHQ-stabilized 2-EHA has a longer shelf life and safer shipping.

3. Choose Flexible Packaging: Drums for small orders; bulk tanks for large-volume procurement to reduce cost.

4. Check Supply Stability: Partner with manufacturers that offer consistent monthly output and on-time delivery.

5. Request Full Documents: COA, MSDS, TDS, packing list, and customs declaration for smooth customs clearance.

Why Choose Reliable 2-EHA Suppliers?

For global importers, quality consistency + supply stability + technical support are non-negotiable. Top Chinese 2-EHA manufacturers offer:

• Industrial-grade 99% purity with tight batch-to-batch consistency

• Competitive FOB/CIF prices vs. European/Japanese producers

• Full regulatory compliance and export documentation

• Flexible MOQs: trial drums to full container loads

• Custom stabilizer and packaging options

Final Thoughts

2-Ethylhexyl Acrylate (2-EHA) is not just a commodity monomer—it is a critical raw material that defines the performance of adhesives, coatings, and polymer products. For importers, selecting the right supplier ensures stable production, consistent quality, and cost efficiency in your regional market.

Whether you are manufacturing tapes, labels, architectural coatings, or sealants, high-quality 2-EHA will directly improve your product’s competitiveness.
