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% |
Suggestion:
Suggested binder: paraloid B66 acrylic binder (Rohm&Haas) in butylacetate ratio 30/70.
How to use:
1/ Mix a small quantity of solvent to the bronze powder to obtain a homogeneous predispersion.
2/ Add predispersion gradually to binder using a slow rotation mixer (50 rpm)
3/ Spray formulation at 20 seconds Zahn 2 or Ford 4.
Note:
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.
