Powder Coating

From Bike Collectives Wiki

Powder Coating is a great durable alternative to paint, around 10 times stronger. Common applications are exercise equipment and outdoor fixtures such as bike racks, street lamp polls, and signs. Anything that takes a beating and/or is exposed to the elements.

Process

Metal piece is burned and/or sand blasted bare.
Metal is dusted with electro-statically-charged (static electricity) pigmented plastic in powder form.
Metal is put in a large oven, plastic melts, the surface is coated with an ultra durable finish.
Metal is ready for use once it cools, no drying required.

Environmental Pros

Powder coatings emit zero or near zero volatile organic compounds (VOC).
Powder coating overspray can be recycled and thus it is possible to achieve nearly 100% utilization of the coating.
Powder coatings lines produce less hazardous waste than conventional liquid coatings.
