What is powder coating?
Powder coating is a combination of pigment and resin that is ground into a powder form and is sprayed on an item to be coated. The powder is charged with high voltage which is then attracted to the electrically grounded item to be coated. The item is heated in a curing oven until the powder flows into a liquid form. After curing for a specific amount of time, the part is removed to cool, leaving a high quality, durable finish.
What is a two coat powder coating system?
By combining a base coat with a top coat, incredible custom powder coat colors can be created. Not only are unique, personalized colors created, but the durability, impact, scratch and wear resistance of the coating is enhanced with a two coat application as well.
What is the shelf life for powder?
Powder generally has a shelf life of 6 months if it is properly stored in a cool, dry place.
The coating is not adhering to the substrate.
Try increasing the oven temperature or dwell time. Try reducing the thickness of the coating by lowering the voltage or spray time.
After curing the coating is chipping off the substrate.
Ensure the oven temperature and cure time is correct. Remember, the cure time starts when the substrate reaches the cure temperature, not when the part is placed in the oven.
After curing the color looks different than the control panel.
If the color looks yellow, the oven temperature is too high or the dwell time is too long. .
The coating seems to have an orange peel finish.
The substrate was brought to temperature too slowly, or the powder was applied too heavily. Ensure the oven has reached the correct temperature before placing the parts in the oven.
The coating has very little impact resistance.
The coating is under cured, had a poor pre-treatment, or the film thickness is to heavy.

K.V. fry base coat 45 K.V. top coat drop down to 30 K.V. keep gun away from part on top coat. When shooting the base coat, the K.V. should be 45. On the top coat, drop to 30 K.V., and keep the gun further away from the part.
How do I get a transparent top coat even?
If you get a substrate that is hard to shoot, double coat the transparent by first putting down a light coat, and then putting down a second medium to heavy coat.
What can be powder coated?
Any metal that is able to withstand the curing temperatures involved with the powder coating process. Generally 350 - 425 degrees F
What are the advantages of powder coating?
Powder coated surfaces are more resistant to chipping, scratching, fading, and wearing than other finishes. Color selection is virtually unlimited with high and low gloss, metallic, textures, and clear finishes available.
