Water based Acrylic Epoxy Hybrid Resin
To design higher performance surface coatings, coating formulators
must choose from myriad polymer chemistries. There are several
classes of water based resins and polymer to choose .The polymer
classes can include 100% acrylic, styrene, styrene acrylic,
butadiene, vinyl acrylic, acrylic-epoxy, acrylic – urethane
hybrids, urethane dispersions of polyeth er,etc.
The polymer holds the coating cohesively (internally) toge ther and
adhesively (externally) to the substrate to which it is applied.
Proper polymer selection can be the most important factor in
determining the physical and chemical properties, as well as
protective capabilities, of the coating.hybrid polymer technology
gives coating formulators new tools to compound continuously higher
performance systems.
An acrylic hybrid coating is prepared by reacting an acrylic
polymer with a large portion of another functional polymer to
produce a coating that combines the beneficial properties of both
the acrylic and the other functional polymer. Often, physical
blends or chemical reaction of two different polymer systems will
provide an incompatible mixture that exhibits the worst properties
of each polymer.
It is crucial in any acrylic hybrid to ensure compatibility among
all polymers in the hybrid through physical blending or chemical
reaction between the components of the hybrid. Once this has been
accomplished, acrylic hybrids can be developed to bring the best
qualities of each polymer to a new coating.
Our Hybrid resins Properties:
1, Excellent anticorrosion performance, especially for the
preparation of anti-rust base coatings.
2, Fast drying speed.
3, Good hardness and high gloss.
4, Excellent salt fog-spray resistance, early water resistance and
weather resistance.
5, Good storage stability.
6, Excellent shear stability, can be grinded with dispersions
directly.
Application:
1, can be diluted by water, Drier has always been added in the
system .It can dry in condition of Normal temperature or low
temperature baking .
2, is high shear stable. It can be grinded in the coating
production.
3, have high gloss and excellent anticorrosion performance, can be
used for the mixed paint, antirust primer, etc., can dry by air or
bake by low temperature, Its coating have excellent gloss, and
antirust performance
4, is stable at neutral or slight alkaline conditions. It is
unstable that it is diluted with acidic or impurity water .PH value
has to be carefully observed in coating production , Precipitation
may occur if acidic pigments such as carbon black ,pH value of the
coating system can be adjusted triethylamine or
N,N-dimthylethanolamine .Viscosity of the dispersion will increase
as the pH value increases.
It is recommended for metal protection projects which require short
and fast construction period.
