AAEM Acetoacetoxyethyl Methacrylate Acrylic Polymer
AAEM Acetoacetoxyethyl Methacrylate Product Description
AAEM(Acetoacetoxyethyl Methacrylate) is one of the most important
products in Shenzhen Prechem's portfolio of acrylates, designed to
improve the performance of acrylic polymers in coatings and
adhesives. Especially for the requirements to improve adhesion,
reduce glass transition temperature (can improve the elasticity and
toughness of the coating), reduce the viscosity of the system
(especially for high solid content system) and improve the
cross-linking density has a very good effect. It also improves the
adhesion of coatings to metal, ore and wood surfaces.
AAEM(Acetoacetoxyethyl Methacrylate) is a methacrylic ester monomer
with a reactive methylene group. Provides improved mechanical and
solvent resistance against water or organic solvents. 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. AAEM can be used with
acrylates and styrene acrylates in water-borne dispersions for
wood, industrial and top coatings.
