Before powder coatings can be applied to metals and fabricated items, the powder itself requires manufacture. This is a carefully combined mixture of polymer resin systems, colour pigments, curatives, levelling agents, flow moderators and additives – all of which are key components in what makes powder coating durable, and superior to standard paint.

​

Powder Coating Components

​

• Polymer Resin:

Polymer resin is the main ingredient of powder coating

systems, and is largely responsible for the durable

properties of the final coating.

​

• Curatives:

In order to increase the strength of the coating and bind

the mixture together, curing agents are used.

​

• Colour Pigments:

Pigments are an essential part of the powder, which add the colour that is present in the coating. There are two types of pigments: inorganic pigments, which create a pale finish, and organic pigments, creating vibrant colours.

​

• Levelling Agents:

Levelling agents are a key component of powder coatings, as they contain the ability to prevent the powder from becoming uneven.

​

• Additives:

Each of the additives present within powder coating serves a different purpose. Some additives are used to reduce surface tension, create a hardened finish, or to gain a matt surface effect.

​

Creating the Powder

​

All of these components are subsequently mixed together at a high temperature, before being cooled. The resulting chips are then ground into a particle-sized fine powder, with a similar texture to flour. A sieving method is also used in order to remove any oversized particles, and to achieve an optimal particle size distribution. Following the sieving process, the powder coating is stored in our facility within air-tight containers, to prevent any moisture pick-up or possible contamination.
