Guide to use
Curing conditions:
210℃/12min; In order to make the coating of the coated object cure evenly and the gloss stable, it is best to use an oven with uniform temperature distribution and a faster heating rate; and reasonably control the curing temperature and time according to the situation of the workpiece.
Pretreatment:
The workpiece must be pretreated before spraying, and it must comply with the provisions of Chapter 5 of GB/T 8013.3-2007. The mass of the chromate conversion film should be between 0.4 and 1.0 g/㎡. The time interval between chemical conversion pretreatment and coating should not exceed 16 hours. In principle, coating should be applied immediately after the conversion treatment is dry.
Workpiece hanging:
When hanging the workpiece, hang it reasonably according to the shape and thickness of the workpiece to improve the powdering rate and yield; and pay attention to keeping the spraying system and the surrounding environment clean to prevent different brands of powder coatings from mixing and affecting the surface effect of the coating.
Powder spraying:
Choose reasonable process parameters, control the voltage, air pressure and powder output. The powder spraying environment should preferably have a temperature and humidity control system. The optimal powder spraying temperature is 15-25℃, and the relative air humidity of the powder spraying room is preferably 45%-55%; in addition, the proportion of recycled powder should be controlled to ensure the color stability of the product.
The recommended coating thickness is 50-80um, otherwise it will affect the coating performance.
During the film formation process, the color will be slightly affected by process conditions such as temperature and thickness. It is recommended that users conduct tests before use to achieve satisfactory results.
