Powder coating companies can cover all kinds of materials and surfaces such as aluminum, glass and other. Their teams are highly trained and experienced and know the best techniques for different surfaces. 

Powder coating is quite a technical process. A dry, electrostatically charged powder – a solvent-free dry mix – made of plastic resins, pigment and fillers is sprayed onto the surface of an item. Then the item is placed in a hot oven which causes a chemical reaction, melting the powder, creating a beautiful finish. In a basic sense, the process ensures the most durable, smooth finish.

Representing over 15% of the total industrial finishing market, the powder is used on a wide array of products. More and more companies specify powder coatings for a high-quality, durable finish, allowing for maximized production, improved efficiencies, and simplified environmental compliance.  Used as functional (protective) and decorative finishes, powder coatings are available in an almost limitless range of colors and textures, and technological advancements have resulted in excellent performance properties.

Powder coating can be used on any object or item that holds and electrostatic charge and can withstand the heat of the oven. The success of the process relies on the prep work – all surfaces need to be clear of any impurities to create the best possible outcome. Companies know the key to a quality long lasting finish, and they always make sure all items are hand prepared to reach the best possible finish. There are times though that further attention is needed, i.e. if the item is rusted or has previously been powder coated or painted it is then recommended that the item be burnt and/or abrasive blasted to remove these layers. 

No matter which application process is utilized, powder coatings are easy to use, environmentally friendly, cost effective, and tough!

The following procedure is recommended for the best finish:

  • Abrasive Blasting
  • Phosphate Treatment
  • Zinc Prime
  • Top Coat

Companies use the latest powdering equipment for applications and have a larger than average 10.5 x 2.5 x 2.5-meter batch oven. They have the facilities to handle almost any size or shape job, and strive to get that perfect finish.

How powder Coating Works

Some of us might think, what is powder coating based on? Powder coatings are based on polymer resin systems, combined with curatives, pigments, leveling agents, flow modifiers, and other additives.  This application method uses a spray gun, which applies an electrostatic charge to the powder particles, which are then attracted to the grounded part.  

Durability

Powder coating is a high-quality finish found on thousands of products you come in contact with each day.  Powder coating protects the roughest, toughest machinery as well as the household items you depend on daily.  It provides a more durable finish than liquid paints can offer, while still providing an attractive finish. This kind of finish is indeed suitable for all kinds of surfaces, whether metal or aluminum. Reputed companies such as Just Powder Coating Melbourne ensure that the surface is free from impurities and rust, in order to complete the job effectively.
