This finishing process is suitable for various materials, including metals, plastics, glass, and medium density fiberboard (MDF), and can provide both functional and decorative surface coatings in a wide range of colors, finishes, and textures that are not readily achievable by conventional liquid coating methods. Chapter Eleven: Powder Curing Process. In either case failure of the finish will occur (which may or may not be immediately evident). All of these factors are critical to the oven's performance.

Share: Image Credit: al7/. Even if a material can withstand the heat, achieving an even coating can still prove to be problematic, especially for thin or multi-color coatings. There is also an alternative option called electrostatic fluidized bed powder coating, which generates a cloud of electrically charged powder particles above the fluidized bed through which a part is passed to be coated. It brings improved durability, a reduced environmental impact, and a higher quality appearance. Table 1 displays an overview of several powder coating systems and cure temperatures. Again, Catalyst 1 is the most effective. Before you can post: click the register link above to proceed. Oven design (infrared vs. convection). If you are not sure of your powder curing parameters, be sure to get them from your powder supplier.

This step determines how well the powder coating adheres to the metal surface, and there are various options for cleaning and prepping the surface. Without adequate control of the curing process, the part being heated can experience under or over cure conditions that will deteriorate the coating quality (table 2). The delta coating Tg (cured coating Tg at full reverse impact minus powder Tg) was calculated for the different epoxy resins. Not only does this allow the user the flexibility to select the color they need, but it allows the applicator to get the effects of the anti-graffiti performance, without needing the clear coat—eliminating a step in application. We can help you with any of your powder coating needs. Typical Cure Development.

Increased durability combined with reduced waste means that a powder coating could actually save you money in the long run. To prove that a paint- or powder-coated product is experiencing the optimum cure schedule, more temperature data is needed. The coating Tg in simulating cure in the DSC showed a smooth coating Tg build up.
