FORMULATING NOTES
®
BECKOSOL AQ 210 can be easily formulated into various primer colors, and Application Bulletins are available
for the following:




High Performance Red Primer Formula 4791-32B
Gray Primer Formula 4669-89B
White Primer Formula 4791-21G
Yellow Primer Formula 4784-71
®
Anti-corrosive pigments are used with BECKOSOL AQ 210 to provide the best metal protection. Reichhold
studies suggest that 50#/100 gallons is an adequate use level. Of the anti-corrosive pigments evaluated, the
phosphosilicates provided the best performance and stability. The two corrosion inhibiting pigments that showed
®
the best performance are WPC Technologies’ Wayncor 226 zinc strontium calcium phosphosilicate and
®
Heubach’s Heucophos ZCP-Plus zinc calcium strontium aluminum orthophosphate silicate hydrate. Several
pigments based on barium, calcium or strontium phosphate showed poor stability or performance when evaluated
in red iron oxide primer formula 4669-27J.
Pigment volume concentration has a strong influence on the corrosion and humidity resistance of the cured film.
Red iron oxide primer formula 4669-27J at 27% PVC has been used as a base formulation for a number of
pigmentation studies that show that formulating to a reduced pigment volume concentration (λ, or PCV/CPVC) in
the 70-80% range can lead to an improvement in coating performance. As an example, high Performance Red
Primer formula 4791-32B uses a mixture of calcium carbonate and Wollastonite at 40% PVC and offers improved
corrosion resistance over the standard 27% PVC formula. Similarly, raising the PVC to 50% by increasing the
quantity of Atomite Star calcium carbonate to around 325#/100 gallons can provide equal or better performance at
a lower cost as demonstrated in High PVC Red Primer Formula 4791-28F. It should be noted that the
modifications to PVC require an adjustment in the use level of other formulation components such as dispersant
®
and rheology modifiers. Each of the primer formulas based on BECKOSOL AQ 210 use talc at around 50#/100
gallons for enhanced resistance to humidity and water.
®
Performance at higher PVC is due, in part, to BECKOSOL AQ 210 being a liquid polymer. This allows the latex
particles to easily deform and flow to fill the voids between pigment particles. Accordingly, studies show that
®
formulations based on BECKOSOL AQ 210 perform at much higher PVC than direct-to-metal styrene acrylic
latex polymers. This is demonstrated in model formulations tested via the electrical resistance method described
by Walter K. Asbeck (JCT CoatingsTech, March 2005). Coatings above CVPC are porous and fail quickly with
this discriminating test method.

STABILITY: UN-AGED VS. AGED RESIN & PAINT
®
BECKOSOL AQ 210 is stable with reactive pigments and demonstrates outstanding stability, both as a neat
resin and formulated paint. In addition to retaining excellent corrosion resistance properties, heat aged paint also
®
maintains a stable viscosity over time. The table below compares the performance of un-aged BECKOSOL AQ
210 resin and paint to that aged after various 50°C heat exposure conditions.
