No matter what you’re powder coating, no matter the size of the line and no matter the type of powder or color you’re shooting, everyone wants to do a great coating job. Yes, it sounds pretty obvious and super simple but there are still a number of things to consider when completing visual checks. Scrub Test Panels are made for scrub resistance testing and are an ideal substrate for abrasion testing of coatings. Low hydrogen-iron powder (EXX28): This electrode is similar to the EXX18 but has 50 percent or more iron powder in the coating. Then cut across that direction so you've cut through the paint to the metal five times left and right, and five times up and down. If there is a little corner here or there that has been pulled off it would likely still be ok and would pass the test. After the powder application, the part should be placed in the curing oven. Posted by on 11 July 2017 . Alternatively, it may be that it did not spend enough time in the oven. Have I performed oven maintenance so I know it’s performing as required? It’s performed by cutting a crosshatched grid pattern into the coating all the way down to the substrate. Performance reliability ; 2. The purpose of this paper is to provide an overview of how these federal, state, and local agencies affect powder coating operations in the United States. Adding a fraction of larger particles (by grinding coarser powder, around 200 µm, and screening through a 70-mesh screen), will produce a leather-ette or "pebble" texture.

If you want more of a controlled testing system than going outside or inside, many job shops use light boxes to control the light. A middle of the range, high quality, good working gauge that you can calibrate and zero out for bare metal can range from $400-$800. Testing before curing, used in quality control during production, is measuring the thickness of the powder itself before it crosslinks into the resulting, even coating. When powder coating is specified, exterior racks shall be treated with a triglycidyl isocyanurate (TGIC) powder coat system. To achieve the best coating performance, each powder has a specified thickness range it must be applied within. Jotun’s Application Guidelines for Metallic Powder Coatings. The three-point method is the most thorough and reliable test method; used for measuring resistance to earth of an installed grounding electrode. Found inside – Page 339In non-destructive testing, the test samples are not destroyed in the process. In destructive testing ... dry powder coating which is white in colour. Did the part have time to reach temperature and THEN spend the required amount of time in the oven? Whereas many powder coaters offer a few colors, we have access to literally thousands of colors, textures, pearls, "flip-flops", candies, and much more. Fortunately solving film thickness issues in powder coating is pretty simple. A good practice is to powder coat a sample piece of galvanized steel to check the overall coating appearance before coating the final piece. Make sure you, your customers and your colleagues or employees are testing in the same way; in the same light, at the same angle, with the same pencils, kits, and meters etc. In powder coating good grounding is critical because powder coating becomes highly charged by a powder coating gun and due to its negative (or positive) electric charge, the powder then seeks a grounded surface as charged particles will generally always seek to return to a neutral state and so the negative charge is attracted to the grounded surface which has a more positive charge. They provide a lot of useful information to you, but you shouldn’t always assume the powder will meet the spec - applying it correctly is a big part of achieving that performance. This test is easy and a must for checking powder coating adhesion! Found inside – Page 8... Toll POWDER PAINT TEST is conducted by William H.

The salt spray test is the oldest corrosion resistance test and the most widely preferred to evaluate anti-corrosion coatings. Coating thickness may not be sufficient or the pieces may not be even covered. Coating shall not vary + or – 5% from data sheet requirements on each material supplied. If you powder coat your parts on the rack itself, whether its in a spray booth or not, the most common method of grounding is to connect the ground wire to the rack. Similar to the mandrel bend test, the impact test deforms a sample panel in order to test the adhesion of the powder coating. 4 Important Methods of Ground Resistance Testing. With most meters, you simply press it to the surface, hold it there a few seconds and get a reading. Generally speaking, if it darkens or yellows and you see some de-glossing, there's a good chance the coating is over-cured.
