Advantages of UV-curable powder coatings
UV-curable powder coating is one of the fastest coating chemistries available. From start to finish the entire process for finishing MDF takes 20 min or less, depending on chemistry and part geometry, making it an ideal finish for applications that require a quick turnaround. A completed part requires only one coat, allowing increased production with 40 to 60 percent less energy than other finishing processes. The UV-curing process is much simpler than other finishing technologies. Curing of a liquid finishRead More …
Why the use of yellow iron oxides in high-temperature-cured coatings is limited
Standard yellow iron oxides are the ideal inorganic pigments to develop a wide range of color shades due to the advantages in performance and cost provided by their high hiding power and opacity, excellent weather, light and chemical fastness, and reduced price. But their use in high-temperature-cured coatings such as coil coating, powder coatings or stoving paints is limited. Why? When yellow iron oxides are submitted to high temperatures, their goethite structure (FeOOH) dehydrates and partially turns into hematite (Fe2O3), which is the crystal structure of red iron oxide. This is why the standard yellow iron oxide that exists before curing becomes darker and browner . This change can take place from temperatures close to 160ºC, depending on the curing time, the binder system and the coating formulation itself.
Coil coating is a continuous industrial process
Coil coating is a continuous industrial process in which multiple layers of organic film are applied and cured on a moving metal strip. The paints used are liquid (solvent-based) and are generally composed of polyesters with acid- or hydroxy- endgroups able to crosslink with melamines or isocyanates to form a complete network with film properties that are tailored to the final application of the coated metal panel (building products, beverage cans, domestic appliances, etc.). The total film thickness is aroundRead More …
