What Is Powder Coating?
Powder coating varies from traditional paint as it does not require a solvent to keep the binder and filler parts in liquid suspension form. Rather, the coating is applied as a free-flowing, dry powder.
- Preparation: A surface clean of oils and debris is key to proper powder coating adhesion. Various chemical and mechanical methods of cleaning are available depending on the material being coated.
- Coating: The coating is applied electrostatically (coating sticks to material surface) with a spray gun. The positive charge of the powder sticks the the grounded charge of the object to be coated.
- Curing: Coated objects are then placed into a 200℃ oven for 10 minutes to 1.5 hours (depending on the material). This causes the powder to melt and begin to flow. This flowing powder chemically reacts to form a extremely strong coating. PermaCoat utilizes infrared curing ovens.
Powder coating is ideal for anything metal such as appliances, aluminum extrusion, car rims, light posts, aluminum railing, etc.
Not only does powder coating produce a thicker coating than conventional liquid coatings without running and sagging, it is more environmentally friendly. Since powder coating requires no carrier fluid, the process emits far less volatile organic compounds (VOCs) than traditional liquid coating.
PermaCoat carries the entire line of Spectrum and Tiger powders. These powders are available to be powder coated or on thier own. Custom colours are also available upon request.
Advantages of Powder Coating
- Powder coating releases almost zero volatile organic compounds (VOCs)
- Provides a much thicker coating compared to conventional liquid coating
- Oversprayed powder can be recycled and reused, resulting in almost zero wasted material
- Powder coating created minimal appearence difference between vertical and horizontal surfaces
- Allows special colours and effects that would not be possible with a liquid based product
