Abstract
If you believe that the selection of guns or bells for your coating application technology is based solely on atomization and transfer efficiency, you are only considering half of the picture. In this paper, we examine some little-known facts about guns and bells — things that your supplier never told you — and how these “secrets” affect the application of waterborne, solventborne, and UV-cure coatings, specifically with regard to surface finish. We distill these factors into practical guidelines to help you select the best applicator for your project so that you may more than double your chances to obtain your desired finish results with high first-pass yields and minimal finish-related rejects.
Introduction
The goal of any finishing operation is to apply a consistent and contiguous coating to the subject part. The coating serves many purposes:
1. Beautification to improve the aesthetic appearance of the part.
2. Protection against such things as scratches, corrosion, UV damage, etc
