Product: β-Carboxymethacrylate
CAS#24615-84-7
L-61045 β-Carboxymethacrylate is a reactive acrylic double bond that is easily copolymerized with vinyl and acrylic monomers in emulsion polymerization and radiation curing systems. Having a lower glass transition temperature can effectively promote adhesion and improve the stability of the emulsion. Having longer side carboxylic acid chains gives good flexibility and promotes more effective interaction between the polymer and the substrate, thus enhancing the adhesion and peel strength. This strength tends to increase with time. β-CEA cross-links with amino, hydroxyl, epoxy, isocyanate functional groups and other structures, and is suitable for water-based, solvent-based and 100% solid systems. Low Tg value (37℃), can be used to adjust the hardness of paint or improve the bonding strength of pressure-sensitive adhesive.
