Many characteristics of powder coat make it a superior
alternative to wet spray paint, including the following.
Dry Film Thickness – Powder coat is 4 to 10 times thicker than traditional liquid spray paint.
Hardness – Decorative powder coat is physically harder than wet paint. This property translates
into significantly greater scratch and chip resistance, and thus generally better durability.
Flexibility – Powder coat can withstand bending without cracking or flaking. Powder manufacturers
publish flexibility test results that demonstrate between 100-800% elongation before failing!
Corrosion Resistance – Proper pretreatment and powder coat finish selection results in corrosion resistance
which can far surpass traditional spray paint. That’s not to say powder coat cannot be scratched, because if you
work hard enough you can scratch anything. With traditional spray paint the rust at a scratch exposed to
the elements will spread and lift the surrounding paint until the finish is ruined. With an appropriate
powder coat finish, a deep scratch left in the elements long enough to ruin spray paint will still be a rusty scratch.
Environmental Impact – Powder coat is an environmentally friendly process. The powder is not a significant
health, fire, or environmental hazard (in dry form it is called a “nuisance dust” because it makes a dusty mess if spilled).
As a comparison, wet paint is flammable, carcinogenic, and full of volatile organic compounds |
