NOTES
The combination of fine bronze grades with coarse bronze grades (i.e. ratio 80-20) will provide a sparkling effect.
The diameter of the spray nozzle should be at least three times larger than the dimension of the largest particles, this to avoid the clogging of the nozzle.
Indicative formulation
Bronze +/- 5%
Binder(incl.solvent) +/- 95%
1/ Prepare vehicle:
-> 78,90% Hybridur 580 of Air Products (urethane/acrylic hybrid base)
-> 0,20% Kelzan AR Xanthan gum thickener.
-> 13,90% water (keep a small quantity of water for the predispersion of the paste).
-> 7% coalescent glycol ether dpnb. Viscosity will be around 18 sec. Zahn 3, PH will be about 8.2
2/ Add between 5-10% of the aquastab paste (predispersed with water) to the vehicle using a slow rotation mixer (max.50RPM)and adjust viscosity.
Dapro DF 1161 defoamer from Elementis can be used if necesarry.
3/ Sieve formulation before spraying to eliminate all potential
agglomerates.
4/ Spray formulation at 20 seconds Zahn 2 or Ford 4.
NOTE
The combination of fine bronze grades with coarse bronze grades (i.e. ratio 80 - 20) will provide a sparkling effect.
The diameter of the spraynozzle should be at least three times larger than the dimension of the largest particles.
Evaluation of stability
for aerosol paints
The stability of the formulation is normally tested at 50°C (in an oven) for the period of minimum one month.
