What is Powder Coating Manufacturer and Why Do We Use Them?

Powder coating is a dry finishing process that has become extremely popular since its introduction in North America over in the s.  Representing over 15% of the total industrial finishing market, 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.

How Powder Coating Works

Powder coatings are based on polymer resin systems, combined with curatives, pigments, leveling agents, flow modifiers, and other additives.  These ingredients are melt mixed, cooled, and ground into a uniform powder similar to baking flour.  A process called electrostatic spray deposition (ESD) is typically used to achieve the application of the powder coating to a metal substrate.  This application method uses a spray gun, which applies an electrostatic charge to the powder particles, which are then attracted to the grounded part.  After application of the powder coating, the parts enter a curing oven where, with the addition of heat, the coating chemically reacts to produce long molecular chains, resulting in high cross-link density. These molecular chains are very resistant to breakdown.  This type of application is the most common method of applying powders.  Powder coatings can also be applied to non-metallic substrates such as plastics and medium density fiberboard (MDF).

Sometimes a powder coating is applied during a fluidized bed application.  Preheated parts are dipped in a hopper of fluidizing powder and the coating melts, and flows out on the part.  Post cure may be needed depending on the mass and temperature of the part and the type of powder used.  No matter which application process is utilized, powder coatings are easy to use, environmentally friendly, cost effective, and tough!

Durability of Powder Coating

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.  Powder coated products are more resistant to diminished coating quality as a result of impact, moisture, chemicals, ultraviolet light, and other extreme weather conditions. In turn, this reduces the risk of scratches, chipping, abrasions, corrosion, fading, and other wear issues.

It's tough. It looks great. And it lasts a long, long time.  In addition to being durable, powder coating is an attractive choice due to environmental advantages.

Powder Coating is a dry finishing process created by an electric charge that causes a dry powder to fuse to the surface of the metal. This is then baked in a curing oven to achieve a smooth coating. It is usually used to create a hard finish that is tougher than conventional paint.

Powder coating does not have a liquid carrier, meaning it can produce thicker coatings than conventional liquid coatings without running or sagging. It produces minimal appearance differences between horizontally coated surfaces and vertically coated surfaces.

Advantages & Disadvantages of Powder Coating:

Advantages

Disadvantages

• A wide range of finishes can be achieved using this process,
• Provides a layer of protection against corrosion, scratches/chipping and fading,
• One of the most economical, longest lasting, and most colour-durable quality finishes available on virtually any type of metal,
• Achieves a consistent colour finish across the metal,
• Powder coatings can produce much thicker coatings than conventional liquid coatings without running or sagging,
• Non-toxic and less flammable than wet spray paint finishes

• Powder coats can leave an 'orange peel' texture on the metal
• The process involves moderate set up costs due to the machinery involved 
• Powders cannot be mixed to obtain different colours 

Applications:

Powder coating is an ideal method if you want to achieve a specific colour match. It can be applied to a range of substrates including steel, copper and aluminium and offers a durable architectural finish. Suitable for both internal and external applications. The latter requires a specific metal and in some instances a further treatment process to cope with saline environments. Our Team of experts can advise which finishing method is most suited to your application.
