What are the benefits of powder coating?

For designers, manufacturers and other industries, powder coating is rapidly becoming the finishing process of choice.

Why? Because powder coating is versatile, adaptable and combines durability with an attractive finish.

It is applied to a broad range of projects, from fabrications to large-scale finishing of metals for use in construction.

What is Powder Coating?

Powder coating is a dry coating method mainly used for applying finishes metal substrates, though you can apply to other surfaces.

It can produce a more even and longer-lasting finish than wet paint, and it is both cost effective and environmentally friendly.

Powder coating consists of a mixture of polymer resin, curatives, fillers and pigments.

You apply it in dry form, using an electrostatically-charged spray. This form of application allows it to adhere effectively to surfaces, and to provide an even covering to them.

Once sprayed on in dry form, the powder coating is then cured by baking it in a special oven.

This curing process causes the dry powder to melt, and to fuse together, forming a tough, even outer shell.

There are two main categories of powder coating:

  • Thermoplastic, and
  • Thermoset.

Thermoplastic powder coatings are manufactured from synthetic materials, such as PVC and polyolefin. They include nylon powder coatings.

Thermoset powder coatings include Polyester , epoxy, epoxy-polyester hybrids and acrylic.

The main difference between thermoplastic and thermoset powder coatings is that thermoset coatings tend to cure harder than thermoplastics.

They undergo a crosslinking chemical reaction during curing, which makes this process irreversible.

What Can You Use Powder Coating For?

The most common use for powder coating is to provide a protective finish for metallic surfaces, objects and products.

This includes large-scale projects such as architectural steel parts. Powder coating helps make them resistant to harsh weather conditions, protecting them against both extreme cold and heat.

Powder coating offers protection from corrosion and rust, which is essential for architectural steel parts, as well as external furniture.

You will see powder coating finishes on building facades, windows, fencing and on stadiums.

Other materials that are exposed outdoors for long periods of time also benefit from powder coating.

As well as large construction projects, powder coating is used in other industries and applications.

It works well for road signs and directional signage, since these materials will be outdoors for prolonged periods.

Billboards are another example. Here, the UV-resistant qualities of powder coating, along with its overall durability, help billboards retain their colour and therefore their visual impact.

Besides large projects, powder coating also works for smaller items and products, including light industrial fabrications.

In the automotive industry, powder coating provides a finish to various components, such as wheel trims and hubcaps. It also coats radiators, shock absorbers and vehicle frames.

Outdoor agricultural machinery and sports equipment benefit from powder coating, as does garden furniture. Light fabrications

A large proportion of the powder coating market is made up of appliances. It gives a bright pleasing finish while protecting products from abrasion and corrosion.

These appliances include vending machines, refrigerators, washers and dryers.

What are the Benefits?

Powder coating is a highly durable form of finishing. It is resistant to colour-fading, protective against corrosion and abrasion and is long-lasting.

It is economical to apply, because you can re-use any under-sprayed or over-sprayed material.

It is also highly efficient in application, reaching difficult areas and coating sharp angles and tight corners.

Powder coating is a rapid process, with items you coat going directly to the oven stage, with no requirement for a flash off period. Unlike wet paint, there are no solvents involved, which greatly speeds up the process.

It is an environmentally-friendly process. Powder coatings contain no volatile organic compounds (VOCs), making them safe to transport and dispose of.

Because they contain no solvents, powder coatings are much safer for operators to use. You can easily remove the dry powder from skin using warm water and soap.

When applying powder coatings in a spray booth, you require less air extraction, which allows for cost savings in ventilation and energy use.

Powder coatings are also much cleaner to use compared to wet paint. Spray booths are easy to wipe down, and you can easily gather up left-over powder using an industrial vacuum cleaner with the right air-driven or dust-tight motor.
