Powder Coating: Thermoplastics and Its Different Subgroups
There is a myriad of finishes that are employed for processing and manufacturing. But over the years, powder coating has surpassed the popularity of wet paint due to the array of advantages that this finish offers. If you are determined to utilise powder coating for your processing and manufacturing applications, you need to note that there are two main types of finishes that you can choose from: thermoplastics and thermosets. While your choice will highly depend on your budget coupled with the complexity of the coating process, both are viable options. This article focuses on thermoplastic powder coating and the different subgroups available.
What are thermoplastic powder coatings?
Thermoplastics refer to synthetic compounds that reformed via the application of high temperatures. These finishes come in various options and are popular because of their innate resistance to both chemicals and water.
What are the subgroups of thermoplastic powder coatings?
Polyolefin thermoplastics: If you are manufacturing products that will be exposed to chemicals or abrasive compounds, then polyolefin powder coatings are an excellent finish for your needs. The powder coating creates a smooth finish on your products that will be visually appealing due to the enhanced adhesion properties of this compound. Polyolefin powder coatings are also best suited to products that will undergo regular cleaning such as laboratory equipment since the coating is resistant to abrading.
Nylon thermoplastics: This is one of the most durable powder coatings that you can choose to finish your items. Notably, nylon is also highly impact-resistant, so you do not have to worry about dents in your finish. Another benefit of nylon thermoplastics is that they are approved for food applications, making them a top choice for items that will be employed to handle foods. Lastly, nylon's friction coefficient is incredibly low, which makes it a staple when finishing conveyor equipment, gears and other items that may be exposed to friction.
PVC thermoplastics: Polyvinyl chloride powder coatings are distinctly sleek. Similar to their nylon counterparts, these finishes are approved for products that will be in contact with food. PVC powder coatings are also ideal when finishing electrical lines since they are great insulators. When it comes to construction applications, PVC powder coating is an excellent finish for hurricane fencing, as it protects the chain link against rust.
Polyester thermoplastics: Products that will be utilised for outdoor application will do well when finished with polyester powder coatings. This finish is typically applied on exterior auto parts, outdoor furniture and other structures that will be routinely exposed to the climatic conditions. Additionally, polyester powder coatings come in a diverse range of hues that will not succumb to fading, even when exposed to UV rays.
