Q. We are going to paint our stampings with either e-coat or powder. Which is cheaper? —A.G.
A. It depends. The material cost of applying powder or e-coat, for the same conditions of performance and quality, will depend on many specific factors, including film thickness, weight, square footage and geometry of the parts, annual volumes, and environmental costs. Typically, the larger the part and the greater the environmental costs, the more the cost analysis will favor the powder.
