Painting Brass Frames
Q. We have a number of brass frames in stock that are not selling well. The boss wants to paint them. They have been in stock so long that they are tarnished. They are both tarnished gold in color and some have tarnished silver elbows. I have never painted brass before and am seeking the easiest/least expensive way of getting it done. L. J
A. There are many products available for painting brass. I’m sorry that I can’t give you specific product names. It is very important that the surface be prepared properly to maximize coating adhesion. What you have to do before applying an organic decorative coating is: 1. Clean the brass surfaces to remove corrosion products. 2. Remove all traces of cleaning compounds, oily soils and other contaminants. 3. Immediately apply an organic coating. These coatings can be applied by brushing, dipping or spraying. They can be conventional coatings, electrophoretic coatings, powder coatings or waterborne coatings. suppliers of these coatings are listed under the various categories in the 2006 PRODUCTS FINISHING DIRECTORY AND TECHNOLOGY GUIDE (www.pfonline.com/suppliers.html).
Some that bears precious metals is, and there are a host of regulations to consider when recycling.
Better adhesion, enhanced corrosion and blister resistance, and reduced coating-part interactions make pretreatment a must.
E-coat can produce uniform finishes with excellent coverage and outstanding corrosion resistance.
