FAQ
What is 2-Hydroxyethyl Acrylate (2-HEA) and what are its primary industrial uses?
2-Hydroxyethyl Acrylate (CAS 818-61-1) is a functional acrylic monomer featuring an active hydroxyl group and an acrylate double bond. It is primarily used in UV-curable coatings, inks, pressure-sensitive adhesives, automotive acrylic resins, and industrial coatings to enhance adhesion, curing speed, and chemical resistance.
How does 2-HEA differ from HEMA?
While both are hydroxyl-functional monomers, 2-HEA contains an acrylate group, giving it faster polymerisation reactivity and higher flexibility compared to HEMA, which contains a methacrylate group with a methyl side chain providing higher hardness and glass transition temperature (Tg).
What packaging options do you offer for bulk export of 2-HEA?
We supply 2-HEA in 200 kg plastic/steel drums, 1,000 kg IBC totes, and ISO tank bulk shipments (approx. 20–24 MT). All containers are compliant with UN transport standards for hazardous chemical export.
What is the standard MOQ and lead time?
Standard MOQ is 1 drum (200 kg) for sample evaluations, while FCL orders (16 MT per 20' FCL) are standard for commercial exports. Production and dispatch lead time is typically 7 to 14 days upon order confirmation.
What safety precautions should be taken when handling 2-HEA?
2-HEA is toxic by dermal absorption and ingestion, and causes severe skin and eye irritation/burns. Always handle in well-ventilated areas using appropriate protective equipment (goggles, full face shield, nitrile gloves, apron). Consult the SDS for detailed emergency protocols.
