2-Carboxyethyl Acrylate (CAS 24615-84-7), also known as CEA or $beta$-CEA, is a functional acrylic monomer produced by the addition reaction of acrylic acid. It contains both a polymerizable vinyl group and a terminal carboxylic acid group. This unique structure allows it to act as an internal plasticizer and a powerful adhesion promoter. It is widely utilized in the synthesis of pressure-sensitive adhesives, UV-curable coatings, and thermosetting resins to enhance mechanical properties and substrate wetting.

• Advantage: Combines high polymerization reactivity with strong polar bonding sites.

• Benefit: Extreme Adhesion: Dramatically improves bonding strength to difficult substrates like untreated metal, glass, and ceramics.

• Advantage: Low volatility compared to traditional acrylic acid.

• Benefit: Improved Work Environment: Reduces pungent odors and inhalation risks in the production hall, ensuring a safer workspace.

• Advantage: Enhances the water-solubility or dispersibility of the resulting polymer.

• Benefit: Process Versatility: Perfect for formulating high-stability waterborne emulsions and eco-friendly coatings.

Used as a reactive diluent and adhesion promoter in UV inks and coatings to ensure the film sticks firmly to glass and metal surfaces.

A key component in pressure-sensitive adhesives (PSA) and structural adhesives to increase peel strength and shear resistance.

Used in the synthesis of waterborne acrylic emulsions to provide freeze-thaw stability and improved mechanical stability of the latex.

Acts as a crosslinking agent in textile finishes and paper coatings to improve water resistance and durability.

• Packaging: 200kg plastic drums; 1000kg IBC tanks.

• Storage: Store in a cool, dry, and well-ventilated area. Crucial: Keep away from direct sunlight to prevent premature polymerization. Contains polymerization inhibitors (typically MEHQ); maintain an oxygen-containing atmosphere above the liquid to ensure inhibitor efficacy. Recommended storage temperature: 5°C - 30°C.

1. Q: Why does the color vary between batches?

   A: Slight yellowing is common due to the nature of the monomers and inhibitors. This typically does not affect the polymerization performance. We keep APHA below 100 for high-end applications.

2. Q: Is this product the same as the "Acrylic Acid Dimer"?

   A: Chemically, it is the primary component of the dimer. While industrial grades may contain higher oligomers, our high-purity grade is optimized for consistent reactivity.

3. Q: Does it require special shipping conditions?

   A: It is not a regulated dangerous good for transport in many regions, but we recommend avoiding extreme heat. In summer, we use refrigerated containers or expedited shipping.

4. Q: How much CEA should I add to my formulation?

   A: For adhesion promotion, adding 3% to 8% to the total monomer weight is usually sufficient to see a significant improvement.

5. Q: Can it be used in food packaging?

   A: Use in food contact materials depends on local regulations (FDA/EFSA). Please consult our technical team for specific compliance data.
