Surface finishing with powder coatings includes electrostatically depositing dry powder thermally cured.
Powder coating is the electrostatically applied of dry powder to the surface. It produces a thin layer providing excellent resistance to wear, corrosion, and abrasion.
Surface finishing with powder coatings includes electrostatically depositing dry powder thermally cured. Powder coating offers a durable surface and is suitable for metal parts made of Steel and aluminum. Their alloys are coated with powder—particularly those used in Vehicle & household appliances. The powder coating creates a strong layer resistant to wear, corrosion, and abrasion.
|Materials||Aluminum, Stainless Steel, Steel|
|Color||Black (20% or 90% gloss), white (20% or 90% gloss)|
|Texture||Gloss or semi-gloss|
|Thickness||60μm to 100μm|
Powder coating’s advantages over traditional liquid coating methods
|High durability: Powder coating is a very durable and long-lasting coating that can withstand high temperatures, chemicals, and UV exposure.|
|High efficiency: Powder coating can be applied quickly and easily and it does not require solvents.|
|High versatility: Powder coating can be used on a wide range of materials, including metals, plastics, and composites.|
|High environmental friendliness: Powder coating does not produce hazardous pollutants during the application process.|
Steps of powder coating:
|Surface preparation: The surface to be coated must be cleaned and prepared to ensure the adhesion of the coating.|
|Application: The powder is electrostatically charged and sprayed onto the surface, where it is then fused into a smooth, even coating.|
|Curing: The coated surface is then heated in an oven to cure the coating, which can take anywhere from a few minutes to an hour, depending on the specific powder used and the thickness of the coating.|
|Inspection: The coating is inspected for any defects, such as bubbles, sags, or holidays (missed spots)|
It is important to note that powder coating can also be applied in a fluidized bed process, where the parts are dipped into a fluidized powder and then cured.
Powder coating is widely used in various industries such as automotive, architectural, appliances, furniture, general manufacturing, and many more.
