Some of the tank interior floors receive a paint touch-up after testing and before shipping because people walk on the inside during the inspection. Recently, I got a customer complaint of soft uncured paint on the tank floor when it was opened for inspection prior to filling. I can’t understand how this happened.
We make a line of scientific instruments and are in the process of introducing a new line. We are having some issues with a gold metallic paint used on them, in terms of the repeatability of its appearance. Since we don’t do painting in-house, the parts in question are outsourced to a custom painting shop. When they come back, they are all over the map in color and gloss.
We are planning to reopen the factory and would be very pleased if you could update us on the latest painting procedures and paint materials used today so we can be competitive in the coming years.
We have to fabricate and paint some fire protection water storage tanks. The specifications call for mill galvanized, not hot dip galvanized steel as the construction material.
My company produces cold rolled steel equipment boxes for both interior and exterior use. Indoor boxes are fabricated from cold rolled steel and outdoor boxes are fabricated from hot dip galvanized steel. After we upgraded our finish system from alkyds to polyesters, we had problems on the hot dipped galvanized boxes in the form of blisters.
To protect and preserve the brass plating, we coat these parts with a clear lacquer using a conventional air spray gun. Needless to say, we get poor coverage on the parts with a lot of overspray. Consequently we use a lot of lacquer. Because of the rising prices of coating materials, I’ve been asked by management to reduce our manufacturing costs.
