CAS 868-77-9
Hydroxyethyl Methacrylate (HEMA)
A hydroxy-functional methacrylate monomer combining a polymerisable methacrylate double bond with a hydroxyl group. It is widely used in acrylic resins, coatings, adhesives, polymer modification and specialty materials.
Product Overview
Hydroxyethyl Methacrylate (HEMA) is a hydroxy-functional methacrylate monomer widely used in the formulation of acrylic resins, coating systems, adhesives and specialty polymers. Its dual functionality allows it to participate in radical polymerisation while the hydroxyl group remains available for subsequent crosslinking or modification. HEMA is produced under controlled conditions with consistent quality performance, supporting reliable formulation work for coating, resin and adhesive manufacturers.
Applications
- UV curing coatings
- Acrylic resins
- Automotive & industrial coatings
- Adhesives & sealants
- Printing inks
- Specialty polymers
