Liquid Coating
Solvent Wiping
I must take issue with your reply to B. L. in the February 2006 issue. Although there is no doubt that he needs to stop using toluene for hand wipe cleaning due to its toxicity and flammability, there are a number of perfectly acceptable alternatives.

We have been asked to recondition and repaint electrical panels. Can you provide the right paint type and specifications for this job?
Read MoreAlternative Pretreatment
We would like to expand our product line to include larger steel buildings whose sections are eight to ten feet long. Because of the size of our processing tanks, we cannot handle larger sections. We now pretreat the sections in an immersion system, and then paint them with a two-coat finish system consisting of an epoxy primer and acrylic enamel. What alternatives pretreatments are available for these sections?
Read MorePainting Stainless Steel Flexible Tubing
I am looking for a method to paint stainless steel flexible tubing for gas and water lines. We have made a few attempts to paint them, however, since the tubing is flexible stainless steel, every time we bend it, it makes a cracking noise, which is most likely the paint cracking from the bending.

Can you give me any insight as to what we are doing wrong or what other products we could use to get better bonding of our finish coat?
Read MoreCoating Interior Surfaces
We have a requirement to apply a liquid dry lubricant product to the inside of an aluminum gun part that is one-inch ID. Our problem is to find a spray tip or system that will work in this confining space and not result in a course finish. We have the mechanism to advance an extension into the part, but can’t find a tip that will perform.
Read MoreIron Phosphate High Temperature Performance
My company paints carbon steel parts with a baking enamel. After painting, these parts are cured in an oven at 300°F for 15–30 minutes. My question is will curing the parts at 300°F adversely affect the iron phosphate coating?
