3. Key Application Scenarios

3.1 Pressure-Sensitive Adhesives (PSAs) for Tapes & Labels

2-EHA is the core monomer for water-based acrylic pressure-sensitive adhesives (PSAs), which are widely used in:

• BOPP packaging tapes for carton sealing, logistics, and e-commerce shipping

• Self-adhesive labels for food, beverage, and pharmaceutical packaging

• Double-sided tapes for construction, automotive, and electronics industries

  Masking tapes for painting and industrial processingIts low Tg ensures permanent adhesion at low temperatures, while its chemical stability guarantees long-term bonding performance.

3.2 Architectural & Industrial Coatings

In the coatings industry, 2-EHA is used to produce water-based acrylic emulsions for:

• Exterior wall latex paints (enhancing weather resistance and stain resistance)

• Interior wall eco-friendly coatings (low VOC, meeting environmental standards)

• Industrial anti-corrosion coatings for metal, wood, and plastic substrates

• Textile coatings for waterproof and flame-retardant fabrics

3.3 Other Industrial Applications

• Sealants & Caulks: For construction joint sealants, automotive sealants, and electronic potting compounds

• Specialty Polymers: For superabsorbent polymers (SAPs), acrylic fibers, and water treatment chemicals

• Adhesive Modifiers: For improving the flexibility and adhesion of epoxy resins and polyurethane adhesives
