Powder Coating

What is Powder Coating

Powder coating is a dry finishing process that involves the electrostatic application of a fine, powdered coating material onto a surface. The powder is typically made up of a combination of finely ground particles of pigment, resin, and other additives.

During the process, the powder is charged with an electrostatic charge, which causes it to adhere to the surface being coated. The coated object is then baked in an oven, causing the powder to melt and flow together to form a durable and attractive coating.

Powder coating is commonly used to provide a protective and decorative finish for a wide variety of metal objects, including architectural cladding, flashings, gantries, gutters, furniture and vents among others. It is a popular alternative to traditional liquid coatings because it is more environmentally friendly, produces less waste, and provides a more uniform and durable finish, which is more resistant to scratching, chipping, chemicals and fading than traditional wet paint.

Materials

At Powdermasters, we take great pride in using only the highest quality materials for our powder coating services. We work with reputable suppliers to source our powders, primarily using AkzoNobel Interpon D, Valspar and Axalta powders.

As an Interpon D approved applicator this is typically our most popular range of powders, specifically formulated for exterior aluminium and steel. This coating is known for its excellent colour, gloss and durability on architectural aluminium and steel. Interpon D powders give a high-quality, long-lasting finish that is weather durable, making it an excellent choice for outdoor applications.

All of our powders undergo rigorous testing to ensure that they meet the highest industry standards for quality and durability. We want our clients to feel confident that the powder coating we apply to their surfaces will last through even the most extreme weather conditions.

In-House Laboratory

We take quality control very seriously, that’s why we have an in-house laboratory where we carry out internal quality inspections on test panels from projects we complete, comprising of 9 different tests. These tests include adhesion testing, impact testing, gloss testing, thickness testing, and more.

Adhesion testing measures the ability of the powder coating to adhere to the substrate it is applied to, ensuring that it won’t peel or chip over time. Impact testing measures the powder coating’s ability to withstand impacts, while gloss testing measures its shine and reflectivity. Thickness testing ensures that the powder coating is applied to the substrate at the correct thickness, guaranteeing an even coating that provides adequate protection.

Our internal quality inspections make certain that our powder coatings meet the highest standards for quality and durability. We use the results of these tests to continually improve our processes and guarantee that we are providing our clients with the best possible results.

Fire Performance

Reaction to Fire is classified through the European Standard BS EN 13501-1.

This standard classifies construction products and building elements from A through to F and determines their reaction to fire performance using data from a combination of 4 small scale reaction to fire tests. For all construction products, the tests take into consideration a fire, initiated in a room, which can grow and eventually reach flashover. In terms of reaction to fire, and in accordance with BS EN 13501-1, Interpon D series D1036 and D2525 are classified as A2, s1-d0:

  • A2 – No significant contribution to fire and will not lead to flashover
  • s1 – Little or no smoke production
  • d0 – No flaming droplets / particles

Building regulations, as defined by UK government’s approved document Part B: Fire Safety, requires materials to achieve either an A1 or A2, s1-do classification for ‘relevant’ buildings above 18m (above 11m for Scotland).
