Protective Coatings on Brass Plated Articles
I have been told by our plating chemical suppliers that the thermal stability of our brass plated articles is between 130 to 150 °C. In this temperature range, we cannot use certain clear lacquers that need higher baking temperatures. We are not in a position right now to use polyurethane lacquers which are used at lower than 130 °C baking temperatures.
Can anyone suggest lacquers that can be baked at lower temperatures without reducing the lasting qualities. The plated and lacquered articles must pass a salt spray test of 100 hours.
