Wrinkle Texture Powder Coating
Collect
DESCRIPTION Wrinkle texture powder coating is more difficult to apply than smooth powders and require closer process control. For instance, some process parameters that should be controlled closely are film thickness, part cure temperature, bring-up time and batch-to-batch consistency of the powder coating. We will discuss these process control parameters one at a time.
Wrinkle texture powder coating will develop their surface texture at a given film thickness range. If the coating is too thick or too thin, then the wrinkle texture will be different or nonexistent. Therefore, you must control the film thickness during application of the powder within the tolerance specified by the coating manufacturer to ensure acceptable results. Maintaining film thickness control entails proper gun settings, environmental conditions of the spray area, part ground and part temperature at time of coating. To a lesser extent booth airflow can also affect film thickness control.
Wrinkle texture powder coating need to be cured at the part metal temperatures and dwell times specified by the powder coating supplier. Temperatures or dwell times outside these parameters will give poor results. Using a catalytic IR system may exacerbate this problem by heating different surfaces of complex part shapes at different temperatures and different dwell times. Therefore, the oven design can be contributing to your consistency problems. The powder supplier and the oven manufacturer should review this situation.
ADVANTAGES ●Tough, durable, lasting coating for metals. Excellent hardness and abrasion / impact resistance gives improved product performance over most liquid coatings. ●Wide range of colors. ●Environmentally friendly outsourcing option to avoid permitting for solvent-based paints. ●Less process variation results in consistent color and appearance of the product. ●High film builds and excellent edge coverage gives better resistance to corrosion with proper pretreatment. ●Coatings can be easily formulated for specific applications such as prolonged exposure to sunlight, the ability to survive in highly corrosive environments, flexibility to allow forming after coating, or high durability and resistance to chipping.
