Product Name:Acetoacetoxyethyl Methacrylate
English Name:Acetoacetoxyethyl Methacrylate
CAS No.:21282-97-3
Aliases:AAEM, 2-(Acetoacetoxy)ethyl methacrylate, 2-(Methacryloyloxy)ethyl acetoacetate, Ethylene glycol acetoacetate methacrylate
Molecular Formula:C10H14O5
Physical Properties:Colorless to light yellow transparent liquid. Density approx. 1.12 g/cm³, boiling point approx. 290°C, flash point approx. 110°C. Slightly soluble in water, readily soluble in alcohols, ketones, esters and other organic solvents. The molecule contains both methacrylate double bond and acetoacetate group, providing dual reactivity for polymerization and post-crosslinking. Stabilizers are required to prevent self-polymerization.
Uses:AAEM is a bifunctional functional monomer widely used in the preparation of self-crosslinking acrylic resins, low-VOC coatings, adhesives and sealants. The acetoacetate group reacts post-polymerization with amines, isocyanates, metal ions, etc., forming crosslinked networks that improve coating hardness, adhesion and chemical resistance. It is suitable for automotive paints, industrial baking finishes, coil coatings, eco-friendly emulsions, textile printing binders and UV-curable systems.
Technical Specifications:
Purity ≥ 98.0%, color ≤ 50 (APHA)
Inhibitor content: BHT or MEHQ, total 200-500 ppm
Water content ≤ 0.2%, acid value ≤ 2.0 mg KOH/g
Packaging: plastic drum 25 kg/drum, 210 kg/drum; black light-blocking IBC tote 1050 kg/tote
Good storage stability; store sealed in a cool, dry place protected from light, avoiding high temperature and direct sunlight
