25584-83-2
Product name: Hydroxypropyl Acrylate
English alias: HPA; 2-Hydroxypropyl acrylate
CAS: 25584-83-2
Molecular formula: C6H10O3
Appearance: Colorless to light yellow transparent liquid
Package: 25kg/drum
Hydroxypropyl Acrylate (HPA) is a functional acrylate monomer containing both acrylate and hydroxyl functional groups, allowing it to participate in both free-radical polymerization and subsequent chemical reactions such as crosslinking. It is a clear, colorless to light yellow liquid with a characteristic ester odor.
Due to its dual functionality, Hydroxypropyl Acrylate is widely used in coatings, adhesives, sealants, and elastomers. It enhances adhesion, flexibility, chemical resistance, and durability of the final polymer product. It can copolymerize with other acrylates, methacrylates, and vinyl monomers, making it a versatile building block in polymer chemistry.
Its hydroxyl group provides a site for further crosslinking reactions with isocyanates, melamine-formaldehyde resins, or epoxy compounds, contributing to improved mechanical and chemical properties.
Item | Specification | Result |
Appearance | Clear liquid | Clear liquid |
Purity (%) | ≥ 96.0 | 97.6 |
Water content (%) | ≤ 0.3 | 0.12 |
Inhibitor (MEHQ ppm) | 200 ± 20 | 205 |
Acid value (mgKOH/g) | ≤ 1.0 | 0.5 |
Conclusion | PASS |
Acrylic coatings – Used in waterborne and solvent-based systems to improve adhesion, flexibility, and UV resistance
Adhesives and sealants – Enhances bonding strength and moisture resistance
Photopolymer resins – Suitable for UV-curable systems, including 3D printing materials and printing inks
Textile finishing agents – Imparts softness, elasticity, and resistance to washing
Plastic and rubber modifiers – Used to improve compatibility, crosslink density, and performance in elastomeric products
Reactive diluent – Acts as a viscosity reducer while maintaining reactivity in various monomer or oligomer systems
Hydroxypropyl Acrylate is a moderately hazardous chemical and may cause skin and eye irritation. It should be handled with appropriate personal protective equipment. Prolonged exposure may cause allergic skin reactions. Ensure adequate ventilation during use. Avoid inhalation or contact with skin and eyes.
Hazard Class: Irritant
Handling Recommendations: Use gloves, goggles, and protective clothing
Disposal: Dispose of contents/container in accordance with local/regional regulations
Store in a cool, dry, well-ventilated area
Keep container tightly closed
Avoid direct sunlight and ignition sources
Storage temperature: 5–35°C
Add inhibitors (e.g., MEHQ) to prevent polymerization during storage
Hydroxypropyl Acrylate is supplied in sealed packaging of different sizes. It is typically available in:
25 kg drums
200 kg steel drums
1000 kg IBC tanks
Ensure transportation complies with local hazardous goods regulations. Protect against heat, sunlight, and physical damage during transport.
