AAEM Acetoacetoxyethyl Methacrylate Specialty Monomer
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.
In architectural coatings, for the selection of a suitable exterior
wall coating, the protective effect and decorative effect are
equally important, because exterior wall paint is exposed to the
external environment and changing temperature all the year round.
It is also important to avoid weathering of the coating. For
exterior building appearance, the performance of the coating, such
as color retention, fade resistance, corrosion resistance, chemical
media and adhesion to the substrate are the most influential
factors. AAEM is commonly used in high quality coatings to improve
adhesion, increase hardness and durability, and provide better
resistance to weathering, moisture and lower dust adhesion.
In metallic coatings, acrylic resins can be chelated with different
metal surfaces by copolymerization with AAEM. This improves the
adhesion and elasticity of the coating, as well as the corrosion
resistance of the coating.
The enhanced adhesive properties of AAEM make it ideal for use as
adhesives and sealants in acrylic systems. Especially in the field
of construction applications, and some in high humidity conditions
still require high adhesion.
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.
