ldzoller Posted May 25, 2007 Report Share Posted May 25, 2007 Which is better, a higher temp and a shorter cure time, or a lower temp and longer cure time? Anyone done any experimenting and noticed a difference in the pp durability? Thanks. Quote Link to comment Share on other sites More sharing options...
jigfisherman Posted May 25, 2007 Report Share Posted May 25, 2007 Myself I think low temp longer time, I will cure mine at 200-250 for about 30min when I have the time. Quote Link to comment Share on other sites More sharing options...
redsnooktrout Posted May 26, 2007 Report Share Posted May 26, 2007 Hey ldzoller It really depends on what kind of powder you use. I use a Polly and the gel time is 90 seconds but for a full cure I have the oven set at 400 for 10min Quote Link to comment Share on other sites More sharing options...
TCCustom Posted May 29, 2007 Report Share Posted May 29, 2007 I got some powder paint from CSI and they included a cure time page and it has different time and temp for each color. TCCustom Quote Link to comment Share on other sites More sharing options...
ldzoller Posted May 30, 2007 Author Report Share Posted May 30, 2007 If different colors need different cure times can anyone post these? I would like to know as some of my powder painted jigs are chipping badly. For example, I made some blue jigs, cured them as instructed on the jar, and then lost almost all the paint off the jig the first time I fished it in rocks. Could the paint have lasted better using another cure time, different from what's on the jar? Any guidance here would be great! Thanks Quote Link to comment Share on other sites More sharing options...
dayooper Posted May 30, 2007 Report Share Posted May 30, 2007 Check out our website at www.tjstackle.com under the powder paint section and we list all the Pro-Tec colors and cure times. One thing you want to do is to put a oven thermometer in before you cure your jigs to make sure that the oven is at the right temperature. Especially if you are using a toaster oven. I have to set my toaster oven at 250 on the dial to have the temp be 350. Thanks, Benjamin Quote Link to comment Share on other sites More sharing options...
LedHed Posted May 30, 2007 Report Share Posted May 30, 2007 One problem with the posted cure times by different manufactures is the accuracy of the temperature monitoring devices that they are using to what you use. They may be using a device that is ± 1°C and you may be using a device that is only capable of ± 5°C accuracy. That is a potential of a 12°C delta. They could be telling you to cure at 325°C for 20 min. and you could be curing at 332°F (or worse) – causing your paint to come out too brittle. Also the location of your temperature sensing device is critical. The heating characteristics of your electric oven (on/off control opposed to modulated control) could be another source of problems. You set it at 315 and it might go as high as 325 before it cuts out and as low as 300 before it comes back on. I use a type T thermocouple placed in the center of a toaster oven and usually cure ~310 to 325°C for 20 + minutes. I don’t normally do single colors and I use various manufactures for my paint (and mix paint as well) so it would be difficult to standardize or create a cure table. Invest in an accurate temperature sensing device (a real good thermometer) and start documenting your cure times. Unfortunately there isn’t a quick fix and you will have to experiment. Go low and slow. I use the Rockwall hardness test to validate my cure times. Quote Link to comment Share on other sites More sharing options...
