Lonzamon™ AAEMA (Acetoacetoxyethyl Methacrylate) is an acrylic monomer used as a copolymer in adhesive & sealant applications.
Lonzamon™ AAEMA from Arxada (formerly known as Lonza) is 2-(Acetoacetoxy)ethyl methacrylate; CAS Number: 21282-97-3. Lonzamon™ AAEMA acrylic monomer is used in coatings and adhesive applications to improve mechanical and solvent resistance. AAEMA has excellent hydrolytic stability and weatherability and a low viscosity and water absorption. Lonzamon™ AAEMA promotes adhesion to metal, mineral, and wood surfaces. AAEMA can also replace styrene in the production of unsaturated polyesters.
