Hannibal Posted December 23, 2016 Report Share Posted December 23, 2016 What might be causing my powder paint to crack? It's only happening to the second color on top of the base color. Quote Link to comment Share on other sites More sharing options...
smalljaw Posted December 23, 2016 Report Share Posted December 23, 2016 I've been using powder paint since 2003, I've never had that happen, even when using different brands and types of powder. So here is what you can do to get more help, describe how you are applying the base color and then the second color. Knowing this can help because it sounds to me like the second color isn't binding to the base color and simply lifting off. Is this happening after you cure or before? Be as specific as you can because we can't help unless we have an idea of how you paint, like are you dipping in a jar or a fluid bed, are you curing in between coats or not at all, so if you can add some specifics someone should be able to help.

Hannibal Posted December 23, 2016 Author Report Share Posted December 23, 2016 The base color is being applied with a fluid bed. The second color is being tapped on top. The base is not cured prior to second color application. The second color is pro tec super glow green. The only other color I have this cracking problem with is the ruby slippers. With that color, it doesn't matter if there is a base coat or not. In both cases the cracking is very visible but you can't feel the fissures at all with a fingernail. If needed I'll try to post pics as well. Quote Link to comment Share on other sites More sharing options...
SW Lures Posted December 23, 2016 Report Share Posted December 23, 2016 Pic's are a pain for more then one reason but it would be very helpful. I redip, tap, airbrush multiple coates a lot. I have never had this issue either. I use Pro Tech also, the glow green I use but the ruby slippers I haven't yet. I keep thinking about a contaminant but it only happens with these two. I'll will assume you do have many other colors by what and how you have stated your problem. I heat and get the powder on quick and then complete all of the work that I can get into the oven then I make the final curing of the powder. Question to make sure I'm getting this right. Do you allow cooling before the second color? Quote Link to comment Share on other sites More sharing options...
cadman Posted December 23, 2016 Report Share Posted December 23, 2016 (edited) I have been powder painting as long as Smalljaw and I have never had that happen. I have been doing multi color powder painting for over 8 years (before it was even popular, similar to your process and still have never had that happen. it has to be a paint issue, because I have never seen of what you are referring to. Pics definitely would help. Edited December 23, 2016 by cadman 1 Quote Link to comment Share on other sites More sharing options...

Apdriver Posted December 23, 2016 Report Share Posted December 23, 2016 Likewise as the rest. Never had any problems like this. The fluorescents tend to wash out if you don't cure the base first is all. Quote Link to comment Share on other sites More sharing options...
mark poulson Posted December 23, 2016 Report Share Posted December 23, 2016 (edited) I cure my two color jig heads at 350 for thirty minutes, in a toaster oven, and don't have any issues. Maybe your second powder should be cured at a lower temp, so you might try curing it at 250 or 300 for thirty minutes, and see if that helps. You might also be getting too much powder on the tap-on side, and that might be shrinking as it cures, causing the lines in the tap coat. A call to the powder manuf. might also help, since they would know the quirks of each color they sell.

Hannibal Posted December 23, 2016 Author Report Share Posted December 23, 2016 I'll try calling pro tec after the holidays and see what they say. Quote Link to comment Share on other sites More sharing options...

SW Lures Posted December 25, 2016 Report Share Posted December 25, 2016 If there no contamenants, as mentioned a bad batch of paint. That doesn't even look like powder paint after a good curing process. Good luck Quote Link to comment Share on other sites More sharing options...
Hannibal Posted December 25, 2016 Author Report Share Posted December 25, 2016 After further analysis of the powders I'm using, all of the super glow colors and the ruby slippers are doing it. The supplier I bought them from repackages them from bulk into their own containers. So that being said, I believe the supply is either bad or contaminated. None of my other colors have this problem including others from the same supplier or otherwise. Quote Link to comment Share on other sites More sharing options...
smalljaw Posted December 25, 2016 Report Share Posted December 25, 2016 It isn't cracked, it looks to be blistered. Since it is the holidays and you might not hear from manufacturer or supplier for a bit I have something for you to try. When you cure that head using the two colors giving you problems, try reducing the temp to 270 and cure for 30 minutes and see if the same thing happens, I say that because it looks as if the paint is rising up or blistering, I never had it happen with powder but when removing old paint with a heat gun that is what happens.

SW Lures Posted December 25, 2016 Report Share Posted December 25, 2016 I never go above 300 in the oven, using a thermometer. All I want is to complete the bond and the sheen look. It would be nice if you could keep us posted. Future knowledge and all that. Quote Link to comment Share on other sites More sharing options...
BLT Posted December 25, 2016 Report Share Posted December 25, 2016 Yes, curious on this one myself. I have the super glow powder in 2 colors, and only used it 1 time. but did not see this. I bake different than some here. My jigs are put in the cold oven, then turned on for 25 minutes, then turned off so it is a slow process of heating up. 1 Quote Link to comment Share on other sites More sharing options...
Fatman Posted January 1, 2017 Report Share Posted January 1, 2017 If you're using a toaster oven go to Wally World, Target whereever you can get an In-Oven thermometer, put it in and set your temp and see if it's coming up the same temp. 1 Quote Link to comment Share on other sites More sharing options...
Kasilofchrisn Posted January 3, 2017 Report Share Posted January 3, 2017 I use all the super glow colors and do multiple colors on one jig and never have had your issues. I just did some 1/8 and 1/4 oz slab jigs in the same exact color pattern you have there with no issues. I buy my super glow powders from TJ's tackle in the one pound canisters. Generally I cure them at 350* for 1/2 hour. 1 Quote Link to comment Share on other sites More sharing options...
Hannibal Posted January 12, 2017 Author Report Share Posted January 12, 2017 Well I figured out the problem. The base color wasn't warm enough to let any other colors crosslink. Glad that delema is over. Thanks to everyone for the support and ideas. Quote Link to comment Share on other sites More sharing options...
