What is powder coating?
Powder coating is a surface treatment used to protect metals and other materials against potentially harmful environmental factors. This coating is applied electrostatically as a free-flowing powder and cured under heat or UV light. It can be applied to any material, but it is commonly used on steel, aluminum, and plastic.
How Does Powder Coating Work?
While these categories differ in application and execution, they all have this in common: a powder is applied to a surface, which hardens under specific conditions. This creates an even, corrosion-resistant surface coat.
What is the gun used for powder coating?
Typically, powder coating applications use one of two powder coating guns: the tribo gun or the electrostatic gun, also known as the corona gun. The corona gun is most commonly used and works on imparting a negative electrostatic charge to the powder particles. After receiving the charge, these particles are shot at the part to be coated through compressed air or mechanical action.
How is powder coated metal accelerated?
The particles are shot towards the metal, either mechanically or through compressed air. Once airborne, they’re accelerated by the electrostatic attraction between the negatively charged particles and grounded metallic surface.
What is the process of coating metals?
Often, metallic parts are chemically treated in processes called phosphating and chromating. Here, the metals are dipped in corrosive acids for a predetermined, concise time, after which they’re rinsed and dipped in phosphate or chromate solutions. This improves the subsequent bond between the metal and powder, improving the surface finish and product performance. The phosphate and chromate solutions used aren’t environmentally friendly. For this reason, many coating services have replaced them with titanium zirconium silanes, which offer similar corrosion resistance and powder adhesion properties.
How many steps are required to powder coat?
The powder coating process requires three basic steps, regardless of the type of powder used: preparation, or pre-treatment, application, and curing. Here is an overview of each step.
What materials require a protective surface?
Non-metallic materials sometimes require a protective surface layer too. These include plastics, carbon fiber, composites, and MDF (medium-density fiberboard). Here, the surface coating will usually protect the part in question from the sun or other harmful environmental factors.
What is 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.
How does powder coating work?
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.
What is electrostatic spray deposition?
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.
What happens to the molecular chains after powder coating?
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.
When was powder coating invented?
Powder coating is a dry finishing process that has become extremely popular since its introduction in North America over in the 1960s. Representing over 15% of the total industrial finishing market, powder is used on a wide array of products.
Is powder coated paint more durable than liquid paint?
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.
Can you powder coat a fluid bed?
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.
What is Powder Coating?
Powder coating is a protective layer that offers a resilient coating to materials that need protection from corrosion. Unlike many other coating processes, powder coating is a dry coating process, which means that it is solid when applied to the base material. Most coatings are applied as liquids for adhesion purposes. Powder coating is applied dry because it is able to use electrostatics to adhere the coating material to the substrate being coated.
How is a Powder Coating Applied?
Perhaps the most common method of applying a powder coating is through the use of a powder coating spray gun. This method propels the powder coating material at the substrate being coated, while also giving the particles an electrostatic charge. The substrate being coated is grounded which attracts the electrically charged particles, helping to form a bond.
What are the different types of powder coatings?
What Are The Types of Powder Coating? 1 Thermoplastics Thermoplastics are a type of coating material that can be set by heat more than one time. This is advantageous for coating removal and other post-curing alterations. Thermoplastics are also generally more ductile, and have an excellent ability to withstand impacts without fracturing. In general, thermoplastics also have excellent chemical resistance. Examples of thermoplastic coating material types include polyester, polyvinyl chloride, and nylon. 2 Thermosets Thermosets are coating material types that form cross-links among their molecular structures when cured. This cross-linking is more permanent than thermoplastics. Once cured, thermosets are less affected by temperature, which makes them ideal for higher temperature applications. They can also be a more affordable coating method than some types of thermoplastics.
