4-Hydroxybutyl Acrylate (4-HBA) – Functional Acrylate Monomer for Advanced Polymers

4-Hydroxybutyl Acrylate (4-HBA) is a highly versatile functional acrylate monomer containing both an acrylate group for polymerization and a hydroxyl group for chemical modification or crosslinking. This dual functionality makes 4-HBA an essential raw material in the development of high-performance polymers and resins with tailored properties.

Widely used in coatings, adhesives, sealants, and specialty resins, 4-Hydroxybutyl Acrylate enhances flexibility, adhesion, durability, and chemical resistance in end products. Its hydroxyl functionality allows for further crosslinking reactions, improving mechanical strength and weatherability in demanding applications.

Industries such as automotive, construction, electronics, and industrial manufacturing benefit from 4-HBA’s ability to deliver improved film-forming properties, enhanced substrate bonding, and long-term stability. It is particularly valuable in waterborne coatings and UV-curable systems, where performance and environmental compliance are critical.
With its balance of reactivity and performance, 4-Hydroxybutyl Acrylate (4-HBA) is a key building block for next-generation polymer formulations.
