What is powder coating?
Metal (and to a lesser extent plastic and some others) components and products often tend to be powder coated when they need to be ‘painted.’ The powder coating is sprayed with a positive charge onto the product with an electrostatic paint sprayer and the charge attaches it firmly where it’s cured (with heat) to then set and stay in place as a chemically-bonded coating.
Powder coating benefits
Powder coating is popular simply because it is one of the most durable, cost-efficient, and environmentally friendly options for painting products.
Thermoset powder coatings in particular are very durable due to the hardwearing nature of thermoset plastics (although it must be noted that you can choose from a wide selection of thermoplastic and thermoset polymers with different properties to powder coat depending on your needs). The polymer coating protects against scratches, chips, and any other abuse that the product may suffer. It’s also water-resistant which can protect items made from ferrous metals. They can fade over time when in the sun, but the coating will not flake away like some traditional paints.
Liquid paints tend to have a shelf-life, too, whereas the powder for powder coating often lasts a lot longer meaning that you’re less likely to need to purchase more. Add this to how fast it can be applied and that a product that has been powder-coated won’t need another coating (unlike painted products – think of your garden fence, for example), and it’s quite a cost-efficient process.
Finally, the electrostatic charge used to attach the powder coating to the product means that no solvents and other harmful chemicals found in paints are used. That lack of VOCs is better for air quality and the staff doing the painting, too.
Can everything be powder coated?
There are a lot of materials that can be powder coated. However, there are some exceptions to the lists:
-
Fabric – Will not tolerate the high heat levels of the curing process.
-
Wood – Isn’t always electrically conductive and cannot always tolerate the extreme temperature.
-
Plastic – Same as wood, it is a material without a charge, and it is not heat-resistant.
-
Glass – Does not always work if the glass cannot withstand the heat.
-
Other items that cannot hold an electrostatic charge.
