We have been getting field complaints that the paint is peeling off in certain areas even before shipping. Apparently, this is because of insufficient degreasing and phosphating with the manually operated steam cleaner.
Some time ago, I remember reading about electron-beam curing somewhere. Unfortunately, I can’t find the article now. I am interested in further information on this subject.
All of a sudden we began having problems with the appearance of our coated products. The irregularities in the phosphate coating are telegraphing or bleeding through the paint when the high-solids coating is applied.
We are presently using an air-drying enamel applied over iron-phosphated, cold-rolled steel. Because of increasing energy costs, we are looking at ways to reduce its usage.
I have been asked to make an honorable artistic memorial for exhibition on the 10th anniversary of the tragedy. For the memorial, a section of the I-beam will be publicly displayed inside an airport, and it may be an open display able to be touched by the public.
In our product line we have an aluminum tube being used as an extension for a carbon mast. We have been painting this tube with white paint, but are having problems with the paint’s durability, as it is chipping.
I need information about different types of paint spray booths (dry filter, water wash, powder coating spray booth, etc.) and the various types of paint curing ovens. Would you please point me in the direction of some good resources?
I have a suggestion for another answer to the question appearing in the January 2011 issue of Painting Clinic regarding problems with creating a clear coating on brass.
Last year at this time we had a large amount of scrap due to paint adhesion failures. Our procedure for metal pretreatment was dip in alkaline cleaner, rinse in cold water and dip in a non-chromate final rinse. To solve this problem, I investigated other means of doing the job without going to an iron phosphate.
