dannyp Posted July 8, 2011 Report Share Posted July 8, 2011 Getting ready to paint up some lead spoons, planning on powder painting them but the first test run show that the paint would crack and flake off when bending the spoon. Are there any tricks/additives to use to makes the powder paint more flexible??? Thanks Dp Quote Link to comment Share on other sites More sharing options...

Be sure to clean eye holes ect. first . If not it's a sure way to get chips and cracks . Also before you powder coat clean the spoons with plain old apple cider vineger gets rid of oxides and slightly etches for better adhesion.

toadfrog Posted July 9, 2011 Report Share Posted July 9, 2011 Ok , bend the spoon first if possible . If that is not feasible . Here I go giving away something of a secret . You can try my process for heat curing .I call it G.H.I. Graduated Heat Increments . Heat the oven to 175 load product 15 min. increase heat 25 * each time for 15 min. until you get to 350* hold that heat for 15 more minutes . Immediately try a bend on the spoon taking care to use rubber grips or something to avoid marks . If that dosen't work we are S.O.L. Quote Link to comment Share on other sites More sharing options...

smalljaw Posted July 9, 2011 Report Share Posted July 9, 2011 If you have to bend the spoon after painting then you may want or should I say need vinyl paint. To the best of my knowlege it is the only paint I know of that is flexible. Quote Link to comment Share on other sites More sharing options...

LedHed Posted July 11, 2011 Report Share Posted July 11, 2011 I do pretty much the same as tf but stay around 315*F for my final cure. Agree with sj - automotive or anything vinyl will probably give you the results you want. Those type paints cure at a lot higher temps but are flexible. The cracking might come from exposing the paint to excessive heat. dp - we do a phlatapus jig that, on occasion, we bend the lip - make it go deeper or change the wobble.
