Pinholes in Paint Film
What is the cause of pinholes in our solvent-based paints, and what steps can we take to eliminate this problem?
Q. I am a manufacturing engineer for a company that makes aftermarket products for the automobile industry. All the parts are produced, pretreated and painted in our factory. We have been using the same solvent-based paints for some time. Painting is done by using conventional air-atomizing spray guns. Recently we started to get pinholes in the paint films. What is the cause of pinholes in our solvent-based paints, and what steps can we take to eliminate this problem? S.D.
E-coat can produce uniform finishes with excellent coverage and outstanding corrosion resistance.
