What is Powder Coating?

Powder coating is a dry finishing method that has become hugely popular since its introduction in America in the 1960s. It now serves over 15% of the manufacturing finishing market and is used on an extremely wide array of items. More and more businesses are shifting to powder coating because of its high-quality, durable finish, maximised production, improved efficiencies and low environmental impact. Used for both embellishing and practical finishes, the powder coating processes that we employ here at UK Powder Coating Services results in flawlessly performing items every time.

​

How Our Powder Coating Process Works

​

The Powder

Powder coatings are comprised of polymer resin systems,

combined with curatives, pigments, levelling agents,

flow moderators and other additives. Prior to beginning

the powder coating process, these components are mixed,

cooled, and ground into a fine powder, with a similar

texture to flour.

​

Pre Application

Before an item can undergo the powder application it

must first be treated to remove any debris and rust on the

surface. At UK Powder Coating Services, we use a

phosphate wash during our powder coating process, which

effectively removes anything from the exterior whilst

neutralising the PH and priming the metal for the powder.

​

The Application

Our powder coating process uses electrostatic spray

deposition (ESD), to adhere the powder to the metal

substrate. This is carried out using our high-tech spray

guns, which apply an electrostatic charge to the powder

particles, attracting them to the grounded surface of the metal.

​

Curing

Once the powder has been applied, the item then undergoes the curing process. This is where the addition of heat in our powder coating process causes the coating to ‘melt’ and chemically react to produce long molecular chains, resulting in high cross-link density. These chains are resistant to breakdown, which is what makes powder coated products so durable.

​

The Benefits of Powder Coating

​

Compared to traditional wet paint methods, powder coating can offer incredible benefits for the item

​

Durable

Powder coating is resistant to chips, dings and corrosion and abrasions.

​

Versatile Applications

Can withstand extreme weather conditions and harsh environments and is used in a wide variety of industries.

​

Environmentally Friendly

Powder coating releases less hazardous waste and harmful gases (VOCs) into the atmosphere, and with our state of the art paint recycling feature, the paint overflow is reduced and our waste is drastically minimised. 

​

Time Efficient

Without having to wait days for the paint to dry, items that are powder coated are ready to go immediately after the curing process
