When it comes to protective and decorative finishes, powder coating has gained recognition as an exceptional choice for both industrial and personal projects. At TQR Powder Coating, we have honed the craft of powder coating, offering our clients an efficient, durable, and environmentally friendly solution. For those new to this popular finishing process, let's delve deeper into what powder coating entails and why it might be the ideal choice for your coating needs.Powder coating is a dry finishing process that has become extremely popular since its introduction in North America back in the 1960s. Representing more than 15% of the total industrial finishing market, this method is used on a wide array of products. It signifies quality but also contributes to sustainability goals. But what exactly happens during powder coating? Let's break it down.The process begins with pretreatment, where the substrate (the item to be coated) is thoroughly cleaned and prepared. This step is crucial as it ensures the surface is free of dirt, oil, or rust, which can jeopardize the coating's performance. Common pretreatment steps include blasting and chemical wash solutions that contribute to superior adhesion of the powder.Once the substrate is prepped, application of the powder begins. Using a spray gun, the powder is electrostatically charged and sprayed onto the grounded object. This ensures an even coat, even on complex shapes, and minimizes wastage. Unlike traditional liquid paints, the powder used contains no solvents, offering an environmentally friendly alternative that reduces volatile organic compounds (VOCs).Then comes the curing stage. After application, the coated item is placed in a curing oven. During this stage, the powder melts and flows, forming a smooth, durable skin. The result is a beautiful, uniform finish that is resistant to scratches, chipping, and fading, far outperforming liquid coatings in both durability and aesthetics. Curing times and temperatures can vary depending on the type of powder used and the size of the part.Beyond physical benefits, powder coating provides aesthetic versatility as well. With countless colors and finishes available, from matte to gloss, and textures from smooth to rough, it allows for customization tailored to meet any design vision. Furthermore, powder coating colors are known for their UV resistance, maintaining their vibrance even in direct sunlight.Now you may wonder, "Where can I apply powder coating?" The answer is almost anywhere.
