Description
2HPA is a reactive acrylate monomer with hydroxyl functionality.It improves adhesion, flexibility, and reactivity in polymer systems.Also enhances crosslinking and surface bonding.Clear liquid, fast curing.
Uses
Benefits
Improves adhesion, flexibility, toughness, and reactivity; hydroxyl group improves polarity and compatibility; enables crosslinking and faster cure in radiation-curable systems.
Application Benefits
Coatings: better adhesion & weatherability; UV/EB resins: lower viscosity + fast cure; Adhesives: improved bond strength; Inks/overprints: improved film formation and durability.

| Storage & Packaging | Store cool (commonly ≤35 °C), away from heat/light/initiators/oxidizers; keep container tightly closed and under air (oxygen needed for MEHQ-type inhibitors); avoid contamination; follow FIFO and monitor inhibitor level for long storage. |
| Product Stewardship | Use trained personnel; implement spill control, PPE, ventilation, and exposure monitoring; prevent release to drains; follow local transport/storage rules; consult SDS before handling. |
| NOTE | Property values vary by isomer ratio, inhibitor level (e.g., MEHQ), purity, and test method. Use your supplier COA/SDS as the specification for purchasing and compliance. |
| NOTICE | This datasheet is compiled from publicly available references and typical industry ranges. It is provided for information only and is not a specification. Always rely on the latest supplier SDS/COA and applicable regulations for your use case. |
Compliance & Standards
Certificate
Commonly provided by suppliers on request: COA (Certificate of Analysis) and SDS/MSDS. Regulatory documents may include REACH/TSCA status declarations depending on manufacturer and destination market.
Safety
Corrosive/irritant acrylate; may be absorbed through skin; use chemical-resistant gloves, goggles/face shield, protective clothing; provide ventilation; keep away from heat/light/peroxides to prevent polymerization; store locked up and stabilized/inhibited under air (oxygen required for MEHQ inhibitors).
