How to Apply PS-5250 Metal Primer for Oil Contaminated Metals:
Quality paint jobs occur with quality preparation, products, and application. Preparation includes cleaning the surface to be painted to remove all contaminants. Some customers do not have the proper equipment to adequately clean parts to be coated with water-based coatings and may only solvent wash parts. For those customers, we have developed Prime Solution 5250. PS 5250, in laboratory tests, mineral oils. Steel test plates were coated with oil and wiped with a paper towel to remove excess oil. The test plates were then sprayed with PS 5250 and air dried for 7 days or heat dried at 160°F for 2 hours.
Prime Solution 5250 was then tested for adhesion using ASTM D3359 cross cross-hatching test method and rated 5B or 100% adhesion. While we would always recommend that surfaces be cleaned as well as possible, tests indicate that PS 5250 can supply a quality paint job on surfaces with some oil contamination.
We recommend you test PS 5250 in your process to determine results in your application. Steel surfaces should have rust, grease, dirt, oil or loose paint removed. We recommend washing with BC 4000 Cleaner/degreaser. Solvent wash and wipe would be the second choice.
