CURING AGENT CHARACTERISTICS
DILUTION PROFILE
Anquamine 721 waterborne curing agent exhibits good viscosity reduction upon dilution with water. Figure 1
represents the viscosity dilution profiles of Anquamine 721 compared to Epilink® 360 and Epilink 701. Epilink 360
is an industrial standard water soluble polyamide and exhibits high viscosity retention on dilution. Experimental
curing agent, Anquamine 721 offers the benefit of a system which shows good viscosity on dilution with retention
of viscosity at low solids for cost effective concrete primer and paint applications. This property is ideal to formulate
and apply high body paint at low solids.

POT LIFE PROFILE
The viscosity profile of experimental curing agent Anquamine 721 exhibits a stable viscosity for at least 60 minutes
to yield cured coatings with a high and constant gloss and hardness throughout the pot life. After 60-90 minutes a
sharp increase in viscosity represents a visible end of pot-life.

Figure 3 – Hardness Development and Dry Speed of Anquamine 721 with Liquid Epoxy Resin @ 23°C
Figure 3 shows the hardness development and Beck Koller, Thin Film Set Times of Anquamine 721 cured with an
unmodified Bisphenol A diglycidyl ether epoxy resin using a mix ratio of 150 PHR. Experimental curing agent,
Anquamine 721 yields coatings with an ultimate hardness of approximately 300 as measured by Persoz pendulum
hardness with undiluted liquid epoxy resin.
It is recommended to use Anquamine 721 at advised stoichiometry of 150PHR (EEW=190). Anquamine 721 can
be used at 10-15% above the recommended loading to accelerate hardness development and increase ultimate
hardness by 25% without negatively impacting other properties.
RECOMMENDED EPOXY RESINS
Experimental Curing Agent, Anquamine 721 exhibits good compatibility with standard liquid epoxy resins based on
Bisphenol A or F. Reactive diluent modified epoxy resin will offer improved handling and formulating latitude within
coating formulations. As with all systems, the inclusion of diluents will retard the hardness development and
ultimate hardness of coated films. Resins modified with reactive diluents, such as Epodil® 748 or hexanediol
diglycidyl ether, exhibit very good compatibility and produce films of high clarity and gloss. A modification level of
approximately 10% to yield a resin viscosity of approx. 2,000mPa.s is ideal to give a good balance of handling and
property development.
DISPERSANTS / DEFOAMERS / WETTING
Defoamers such as Surfynol® DF62 and BYK 045 are very suitable for use in coating formulations to give optimum
air release and surface properties. ZetaSperse™ 1600 and Disperbyk 190 can be used to effectively aid in wetting
out pigments and increasing flow and levelling properties to give a system which yields good surface and flow
properties.
RHEOLOGY MODIFIERS
The Rheology of formulations with Anquamine 721 can be effectively controlled with the use of Thixotropic agents
such as polyurethane thickeners and Bentonite clays. Tafigel® PUR-55 (Münzing-Chemie) has shown good
Thixotropic properties in paint formulations with Anquamine 721, allowing for good application viscosity and anti-
sag performance. However, due to the inherent thixotropy of Anquamine 721 systems can be formulated without
the need of external thickeners.
START POINT FORMULATION GUIDELINE
GREY MATT PRIMER (ROLLER, BRUSH & SPRAY), WATER DILUTABLE

This formulation is ideally suited as a primer or topcoat for concrete floor coatings at 100-
300 micron applied film thickness. The highly filled paint provides a cost effective, fast touch
dry and good hardness (6H) when cured.

DESCRIPTION
This grey concrete primer system is prepared by mixing Component A with Component B for
2-3 minutes using hand mixing to produce a homogeneous mixture. Once mixed water may
be slowly added to give the desired application viscosity and mixed for 1-3 minutes before
application. To produce a coating with an initial application viscosity of 300-500 mPa.s,
addition of 10 – 15% water is required.

DESCRIPTION

This clear coating which is ideal as a concrete primer system is prepared by taking 60 parts of
Anquamine 721 and diluting to 40% solids. This is then mixed with 40 parts of component B
for 2-3 minutes using hand mixing to produce a homogeneous emulsion. Once the emulsion is
formed, water is slowly added to give the desired application viscosity and mixed for 1-3
minutes before application. To produce a coating with 40% mixed solids 60 parts of water is
required, this will give an initial application viscosity of 100 – 200 mPa.s.
