AAEM(Acetoacetoxyethyl Methacrylate) is a methacrylic ester monomer with a reactive methylene group, used to formulate high-solids solution acrylic resins and acrylic emulsions for lower VOC emission industrial and architectural coatings. Provides improved mechanical and solvent resistance against water or organic solvents. It can be used in pesticide intermediates, high solid acrylic resin solution, reaction monomer for photocuring, polymer for cross-adhesives, polymer for cosmetics, pharmaceutical intermediates, self-crosslinking acrylic emulsion, and can replace N-hydroxymethyl acrylamide, diacetone acrylamide, HEMA, etc, and it has better control of reaction time and makes the better product performance. Exhibits good weatherability, hydrolytic stability, low water absorption and low viscosity. It crosslinks with primary aliphatic diamines, formaldehyde, isocyanates, metal ions and activated double bonds (Michael-addition), at room temperature.
