Conductive Liquid Primers

Question:

Per your article in PF, could you provide additional information on the product “Rans-Prep”? Who makes it? D. T.

Answer:

I don’t have any idea who makes it. In fact, I think several companies make conductive liquid paint primers, which have often been referred to as “Rans-Prep.” I first heard the term when I worked for Ransburg Corporation (by the way the “Rans” in “Rans-Prep” comes from the Ransburg Corporation, named after its founder Harold R. Ransburg). I was in the powder group known as Ransburg-Gema and working on a project where we had to apply powder to fiberglass. One of the “liquid guys” from the Ransburg Electrostatic side of the business recommended that we use “Rans-Prep.” At that time, several liquid paint suppliers had known of this material and offered their own formulations. Maybe you can locate a supplier for a similar material using the “conductive liquid paint primer” description and don’t call it “Rans-Prep.” I think the problem may be that only us “old guys” remember the Ransburg Corporation (now part of ITW Finishing), and the “Rans-Prep” name has become nothing more than slang for liquid conductive primers. Good luck.
