2-Hydroxyethyl Acrylate
CAS 818-61-1
Overview
Hydroxyl-functional acrylic monomer for UV/EB curing systems
Applications
- UV/EB curing coatings — reactive diluent and cross-linker in radiation-curable formulations
- Pressure-sensitive adhesives (PSA) — improves adhesion and cohesion balance
- UV inks and overprint varnishes — reactive diluent reducing viscosity
- Polymer modification — hydroxyl functionality for polyurethane and thermoset systems
- Textile, leather and wood coatings — hardness and chemical resistance
