The Anochrome Group provides expert powder coating services to clients around the world. Powder coatings offer a tough, durable finish highly resistant to chipping, cracking, peeling, and fading. This makes them suitable for long-lasting applications. They also offer excellent protection against corrosion and rust. This means they’re ideal for outdoor or marine conditions.
Another great benefit of power coatings is that they’re environmentally friendly. This is because they contain few to no VOCs. Power coating can apply to a huge range of industries and we can offer a wide range of colours in a high quality finish.
Powder coating is a method of coating a part in a polymer powder using directional spray equipment. The coating is typically comprised of three components, pigments, resin and fillers. Pigments provide the colour of the coating and determine the quality of the finish – glossy, matte, metallic etc. The resin is the binder that holds the powder together and adheres to the surface of the object when heated. Fillers may be added to adjust the texture or other properties of the coat.
The big difference between powder coating and wet spraying is that the wet spray principle requires a carrier or solvent to allow the material to be successfully atomised and transferred from gun to substrate. When powder coating, the powder is carried out of the spray equipment with low pressure air and is drawn towards the substrate via an electrostatic charge. The powder is then cured via an oven. This causes the powder to melt and flow across the surface of the substrate, fusing the particles together in a chemical crosslink. When removed from the heat and allowed to cool the coat becomes hard and durable.
Parts processed with manual input, generally means reduced capital outlay on bespoke tooling.
