4-hydroxybutyl acrylate, ≥ 95%

4-Hydroxybutyl acrylate (HBA) is a hydroxyl-functional acrylate monomer that offers improved adhesion, flexibility, and chemical reactivity. It is used in high-performance coatings, adhesives, and biomedical materials due to its ability to undergo crosslinking reactions. It also increases hydrophilic properties of polymers when copolymerized into a range of acrylate and methacrylate systems and is used in polymers for contact lenses and other ophthalmic devices.

Applications:
Adhesives & Sealants: Enhances adhesion strength and moisture resistance.
Coatings & Surface Treatments: Provides chemical and abrasion resistance.
Biomedical Hydrogels: Used for tunable swelling and biocompatibility.
UV-Curable Resins: Improves curing speed and mechanical properties.
Personal Care Polymers: Adds hydration and film-forming benefits.
