AAEM Acetoacetoxyethyl Methacrylate Monomer CAS NO.21282-97-3
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.
Compared to the solvent system, the water-based system provides us
with a more environmentally friendly and healthy alternative.
However, water is more difficult to fully evaporate from the system
than other organic solvents. Therefore, water-based systems reduce
the drying time of the coating by increasing the solid content as
much as possible. Unfortunately, most high solids systems also have
very high viscosity, which makes it very difficult to operate. The
addition of AAEM reduces the viscosity of the acrylic polymer
system, allowing the builder to easily use a water-based system
with zero solvent volatilization.
The addition of AAEM helped improve the durability and toughness of
water-based polymers, which, when cured at room temperature, tend
to have intrinsic performance deficiencies compared to solvent
systems, such as durability and toughness, and significantly
improved scratch resistance and dust adhesion.
The enhanced adhesive properties make it ideal for use as adhesives
and sealants in acrylic systems. Especially for applications in the
field of architecture. And where high adhesion is still required
under high humidity conditions.
