Hong Kong Office Chair Spraying

There are mainly two spraying processes for the steel frames of office chairs in Hong Kong: ordinary spraying and baking paint. The baking paint process has more advantages in many aspects and is a common choice for high-end office chairs.

Curing Process

Ordinary spraying usually refers to electrostatic powder spraying or self-drying paint, which mainly relies on physical drying or low-temperature baking to form a film. This curing method is relatively simple and has lower requirements for equipment and technology. However, if the process is not properly controlled, phenomena such as orange peel and sagging are prone to occur, affecting the flatness and aesthetics of the steel frame surface. Baking paint, on the other hand, must undergo high-temperature baking, typically within the temperature range of 180℃ - 250℃. In a high-temperature environment, the paint undergoes a chemical cross-linking reaction, forming a dense network structure. This curing method makes the coating more stable and robust.

Coating Performance

Ordinary spraying has relatively low hardness, and the surface is prone to wear and whitening after long-term use. Its adhesion, scratch resistance, corrosion resistance, and yellowing resistance are relatively weak. For chair steel frames, which are frequently in contact, susceptible to sweat erosion, and need to be moved frequently, the coating of ordinary spraying may not provide sufficient protection, and rusting or peeling is likely to occur. Baking paint has significant advantages. It has extremely strong adhesion and can tightly adhere to the steel frame surface without easily falling off. At the same time, its scratch resistance, corrosion resistance, and yellowing resistance are far superior to those of ordinary spraying, providing more durable protection for the steel frame and effectively preventing rusting and peeling.

Final Texture

The surface texture of ordinary spraying is relatively ordinary, and its gloss and uniformity may not be as good as those of baking paint. The surface of baking paint is flat and smooth, with high and uniform gloss, and rich colors. It has a high-end metallic texture, which can enhance the overall grade and aesthetics of the office chair.

Industry Standards and Application Scenarios

In terms of industry standards, high-end office furniture generally requires the use of high-temperature electrostatic powder baking paint processes to meet environmental protection and safety standards. In terms of application scenarios, indoor high-end leisure chairs and office chairs mostly use baking paint processes to enhance product quality and grade; while outdoor or low-cost scenarios may use ordinary spraying processes to save costs.
