What is Hydroxypropyl Acrylate？

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.

Application:

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
