What Is Powder Coating?

Powder coating is a polyester-based coating method that uses consistently sized, dry polyester microbeads. The beads have an electrostatic charge that enables them to adhere to base materials. Powder coating creates a stronger, more durable and more resilient finish than paint and is useful on products that will need to stand up to harsh weather conditions or provide years of quality use.

Applying powder coating works via a different process from the one used to apply paint and other coatings. Most coatings go on as liquids because their liquid forms are more adhesive than their dry forms. Liquid paint, for instance, goes on as an evaporating solvent.

In the powder coating process, manufacturers typically apply dry powder electrostatically with a spray gun and then cure it in a curing oven or beneath ultraviolet light, giving it exceptional durability and resistance. The curing process also allows manufacturers to apply powder coating to various materials beyond traditional metals, including carbon fiber, composites, fiberboard and plastics.

Most powder coating materials take one of two forms:

  • Thermoplastics: Thermoplastics, such as nylon and polyvinyl chloride (PVC), can go through heating, molding and curing more than once. They are easy to alter post-curing, and their coats are easy to remove. They are also ductile and chemically resistant.
  • Thermosets: Thermosets, including epoxy resins and phenolic resins, can go through curing only once. Once cured, though, they have greater heat resistance and are more suitable for high-temperature applications.

 

Powder Coating Advantages

These are a few of the benefits of using powder coating on metal surfaces:

  • Hardness and durability: The curing process makes powder coatings tough and durable. The finished coating will not peel or flake.
  • Corrosion resistance: The powder coating creates a barrier to protect against many different types of corrosion, including rust. Many natural metals like steel rust over time with exposure to moisture and oxygen. Powder-coating creates a protective barrier so the metal remains rust-free. Untreated aluminum does not rust, but it can oxidize to form a chalky-white substance in place of rust. Most metal parts designed for outdoor use have powder coatings to protect them from the elements and the resulting deterioration.
  • Visual appeal: Powder coating also imparts an aesthetically appealing finish to metal surfaces. It is useful on metal products designed for attractiveness, such as patio furniture or visible building components, because it gives them an elegant look.
  • Cost-effectiveness: Another advantage of powder coating is its cost-effectiveness compared with other strengthening methods. Manufacturers can create strong products with specific, durable alloys, but those alloys tend to be costly. For instance, stainless steel is renowned for its strength and corrosion resistance but is expensive to produce and obtain. Using carbon steel and coating it with protective powder is a much more economical solution.
  • Environmental responsibility: Powder coating is also relatively environmentally friendly. It contains almost no volatile organic compounds (VOCs) and no heavy metals like chrome.

Powder-Coated Steel

Powder-coated steel combines the naturally robust character of steel with the longevity and corrosion resistance of powder coating. Its strength, durability and resistance to many types of corrosion make it suitable for use in outdoor furniture, indoor furniture frames, metal canopy frames, metallic roofs, windows and doors, scaffolding, cranes and trailers. Many outdoor products designed for strength use powder-coated steel.

Is powder-coated steel rustproof? It is, up to a point. Powder-coated steel is highly resistant to rust in most cases, so it won&#;t develop unsightly rust patches or leave red streaks on a patio or building facade. However, if it sustains damage, small cracks in the coating may appear, admit moisture and allow rust to form. If you&#;re looking for a strong, rustproof material, however, powder-coated steel is the closest you are likely to find.

Here are a few of the benefits of using powder-coated steel:

  • Strength: Powder-coated steel is tremendously strong. It provides security and peace of mind in architectural applications and makes for dependable furniture as well.
  • Longevity: Powder-coated steel is highly durable. Its efficient coating makes a tight seal to keep out contaminants and enable the steel to last longer.
  • Thick, consistent finish: An paint application may clump in some areas and remain thin in others. Powder-coating provides a thick, even finish for more consistent protection.
  • Aesthetic appeal: Untreated steel may look rugged and unrefined, but powder-coated steel can be beautiful. Finishes in numerous styles and colors mean powder-coated steel products enhance the decor of any building.
  • Corrosion resistance: Like other powder-coated metals, powder-coated steel is highly corrosion-resistant. Its coating acts as an impenetrable barrier to keep moisture and other contaminants out, so corrosion cannot gain a foothold in the metal.

Powder-Coated Aluminum

Powder-coated aluminum blends the lightweight properties of aluminum with the resistance and longevity of powder coating. It is easy to transport, and it stands up well to harsh weather conditions without corroding. It is highly suitable for products such as metal patio furniture, metal railings, doorknobs, door frames and window frames.

  • Durability: Despite its lightness, powder-coated aluminum is tough. It can withstand rigorous outdoor use and last for years.
  • Elegance: Though it is strong and dependable, powder-coated aluminum is also aesthetically pleasing. The variety of possible colors and stylish shapes makes powder-coated aluminum products appealing as furniture or decor.
  • Corrosion resistance: Like other powder-coated metals, powder-coated aluminum is advantageous because of its corrosion resistance. It shuts out moisture and other contaminants to keep products corrosion-free.

The Major Benefits Of Using Metal Coatings

The Major Benefits Of Using Metal Coatings

Metal coating is a process where a metallic coat is applied to metallic or non-metallic objects and surfaces. Applying metallic coating on an object offers a range of benefits to the surface being coated. For example, the metallic coating can be used to protect objects from corrosion, the effects of moisture, and much more.

What are the benefits of metal coating? Here is what you need to know about this.

Protection

Metal coating is great for corrosion protection which is why it is used in industries where equipment is exposed to moisture. This includes marine environments, offshore rigs, and anywhere else where there is a high risk of corrosion. This process works by applying a coat made of a metal that does not corrode easily.

Durability

The use of metal coating on surfaces and objects often helps to make the objects a lot more durable than they otherwise would be. Heavy machinery that is exposed to a high risk of wear and tear is typically coated with a metal coating. By creating a barrier between the surface and the elements, the metal coating helps to reduce wear and tear and increases the lifespan of machinery.

Aesthetics

Metal coating can often help to improve the aesthetic appeal of an object. This is because metal coating often creates a glossy or matte finish which improves the look of an object. This is one of the reasons why metal coating is often used for facades, high-value furniture, and objects where the finish is important. Metal coatings are also used in the arts for precisely this purpose. It is common to find this process being applied to sculptures in order to enhance their looks. An additional advantage of using metal coating for such an application is that the sculpture is also protected from the effects of rain and wind.

Better Performance

Metal coating is often used to improve the performance of objects. For example, by coating objects with a particular type of metal coating, one can improve electrical conductivity as well as thermal conductivity. This type of coating is usually found in the automotive industry. Metal coating can help improve engine performance.

Cost-Effective

Metal coating is one of the most cost-effective methods of protecting surfaces. This is part of the reason why it is popular across many different industries. Not only it is cost-effective to apply but it can also help reduce costs for a company in other ways. For example, by protecting machinery and surfaces from corrosion, metal coating helps to improve the life of such objects and significantly reduces the cost of maintenance. Using metal coating also leads to less downtime as machines are less likely to break down. This way the productivity of the entire facility is improved.

Eco Friendly

The use of metal coating helps to protect the environment in many different ways. The first is that by applying metal coating on objects, one extends the life of such machinery. This in turn means that there is less landfill as machinery is used for longer periods than would be typically the case. The process of applying a metal coat on an object is also relatively easier and more eco-friendly than most other approaches.
