  • Copper vein powder problem

    Hi my name is Terry,
    I am new to the forum but not new to powder coating and I'm having a issue with shooting copper vein powder.
    I have never shot this powder before and have discovered even with my gun on the lowest setting (15kv) The copper element of the powder sticks to the inside of the gun and doesn't go to the substrate. When I cook it there's little if no veining pattern. If I turn the power off and hot coded it turns out perfect. I was wondering if anybody has experience this or heard of this problem.

    Sounds like a grounding issue. The copper part isn't the vein it's just an additive. if the veining isn't appearing, you're not getting it on thick enough. I would check your ground.
