Ethoxylated bisphenol A dimethacrylate

Ethoxylated bisphenol A dimethacrylate (CAS 41637-38-1) is a bifunctional methacrylate monomer used as a reactive diluent and crosslinker in UV- and peroxide-curable polymer systems.

Where is Ethoxylated bisphenol A dimethacrylate used?

• UV-curable coatings and inks: hard, chemically resistant films with controlled flexibility
• Wood, metal and plastic substrates
• Dental and industrial adhesives: base monomer for toughness and dimensional stability under cure
• Photopolymer printing plates and packaging laminates: fast cure response and strong substrate adhesion
• Composite and structural adhesives: crosslink density and mechanical performance in fiber-reinforced systems
• Its ethoxylated backbone reduces viscosity versus standard bisphenol A dimethacrylate, improving processability without sacrificing crosslink density.

Good to know: Standard commercial grades vary in ethoxylation level, typically EO2 to EO10, which affect viscosity, flexibility and hydrophilicity. Buyers should confirm ethoxylation degree and methacrylate equivalent weight against formulation requirements.
