Our powder paints give metals a long-lasting lustre that goes for years. Made for both outdoor and indoor, the paints are able to withstand harsh weather elements without losing
their appeal. Wrought iron balustrades, window grills, metal gates, curtain rods and outdoor furniture come alive with textured paints of various colours.
In contrast to the liquid coating process, which utilizes a liquid coating suspension, powder coating is a dry finishing process which employs powdered coating material. During the powder coating process, the powder is applied to a substrate’s pretreated surface, melted, and then dried and hardened into a protective/decorative coating. There are three stages to this process: surface preparation, coating application, and heat curing. Each stage employs a set of materials and equipment indicative of its particularities (e.g., the curing stage utilizes a curing oven), and, when properly completed, contributes to the production of a durable, even surface finish.
Benefits of Powder Coating
The powder coating process offers several advantages over conventional liquid coating methods, including increased durability, capabilities for more specialized finishes, less environmental impact, faster turnaround time, and lower material costs.
In addition to being available with a wide range of finish options, powder coatings are generally more long-lasting and durable than liquid coatings. They demonstrate higher resistance to impact, moisture, chemicals, and wear, and offer greater protection from scratches, abrasion, corrosion, fading, and general wear. These characteristics make them well-suited for high use and high traffic applications.
Another advantage of the powder coating process is the lack of solvent and carbon dioxide emissions, hazardous waste material that requires disposal, and, generally, surface primer requirements. These exclusions limit the amount of toxic and carcinogenic substances being released into the environment throughout the process and contribute to the recognition of powder coating as a more environmentally-friendly alternative to liquid coatings.
The powder coating process can have much lower long-term costs compared to the liquid coating process due to its having a generally quicker turnaround and greater coating material utilization. Since the curing stage of powder coating allows powder coated parts to be assembled, packaged, and shipped immediately after the part is cool, parts spend less time in inventory which enables manufacturers and finishing service providers to have a faster turnaround and less storage space requirements. The powder coating process also allows for overspray material to be collected and recycled instead of wasted, which decreases the amount of waste product requiring disposal, increases the coating material utilization rate, and lowers the cost of materials over time.
