WHAT IS POWDER COATING?

Powder coating is exactly that.  Powder pigment is electrostatically charged as it is ejected from the spray gun using low pressure air.  The powder particles then deposit on the oppositely charged part, evenly coating it.  Once coated the part is placed into an oven at 400° F for 10 minutes which melts the powder allowing it to flow like paint and then cures the coating.  When removed from the oven the part is allowed to cool and ready to ship.

Powder coating requires the part surface to be clean and when possible clean, bare metal to ensure a good electrical path.  Part preparation requires removal of rust, paint, and other contaminants through stripping or media blasting.  Final preparation is a wash stage to remove blasting dust and oils/solvents.

Powder coating has several advantages over paint:

Powder coating does not require liquid solvents for pigment suspension - safer and more environmentally friendly

Powder coating provides much thicker coatings than painting - incredible durability, scratch resistance, and metal protection

Powder coating produces little hazardous waste, unlike painting or plating

Metallics, pearls, primers and clear coats available, just as for paint

                 

Unlike paint powder coating can provide many types of texturing effects:

                                

           

Copper vein on a product:

Powder coating's texture and thickness can conceal many minor flaws in the part surface, allowing less part preparation after fabrication to achieve a high quality finish  

Powder coating disadvantages:

Can only be applied to materials that can take an electric charge - primarily metals, but new technology allows the coating of some wood and plastics

Can't be buffed or polished after curing

Contains some texture or "orange peel" on large flat surfaces - new technology powders are improving this

POWDER COATING PROCESS

PROJECT:  Powder coat stock Nissan Pathfinder rims

Step 1: Remove rims from vehicle, unmount tires, and remove any plastic/stickers/weights

Step 2:  Prepare surface.  This may include washing with a biodegradeable cleaner or alkaline cleaner, media blasting (shown), and blown clean

Step 3:  Hang parts on carts ensuring a good ground path for the static charge

Step 4:  Spray powder onto parts and bake in the curing oven per manufacturer's instructions

Step 5:  Reinstall onto vehicle and enjoy.
