Whether you're developing innovative coatings or specialized adhesives, HPA delivers the performance edge needed for competitive products.

Safety and Handling Guidelines

HPA is a reactive material that requires proper handling to ensure safety. It is toxic by inhalation and skin absorption, corrosive to tissues, and may polymerize exothermically if exposed to heat, contaminants, or initiators. Always use in well-ventilated areas with appropriate PPE, including gloves, goggles, and respirators.

• Storage: Keep in cool, dry conditions below 25°C in tightly sealed containers, away from light, heat, and oxidizing agents. Inhibit with 100-200 ppm MEHQ.

  
  

• Transportation: Classified as UN 3082 (Environmentally Hazardous Substance, Liquid, N.O.S.) under DOT regulations.

  
  

• First Aid: For skin contact, wash with soap and water; seek medical attention. In case of inhalation, move to fresh air and provide oxygen if needed.

Frequently Asked Questions (FAQs)

What is Hydroxypropyl Acrylate (HPA)?

HPA is a monofunctional acrylic monomer with the formula C₆H₁₀O₃ and CAS number 25584-83-2. It is a clear liquid used primarily as a co-monomer in polymer synthesis to improve adhesion and resistance properties.

What are the main applications of HPA?

HPA is commonly used in thermosetting coatings, adhesives, resins, and medical polymers. It enhances chemical resistance, crosslinking, and scratch resistance in products like paints, inks, and composites.

How should HPA be stored to prevent polymerization?

Store HPA in a cool, dark place at temperatures below 25°C in containers with added inhibitors like MEHQ. Avoid exposure to heat, light, or contaminants that could initiate unwanted reactions.

Is HPA soluble in water?

Yes, HPA is soluble in water and miscible with alcohols, ethers, and most organic solvents, making it highly versatile for aqueous and solvent-based formulations.

What safety precautions are necessary when handling HPA?

HPA is corrosive and toxic via skin absorption or inhalation. Use PPE, ensure ventilation, and follow SDS guidelines. In case of exposure, seek immediate medical help.

Can HPA be used in UV-curable systems?

Absolutely. Its reactivity makes it ideal for UV-curable inks and coatings, where it promotes rapid curing and strong film formation.
