What powder coating is
Powder coating is a surface finishing process that involves applying thermosetting or thermoplastic powders to metal surfaces such as sheet metal. Unlike liquid coating, it does not use solvents and ensures a smooth, durable and sustainable finish.
The process involves applying the powder electrostatically to the component and then polymerising it in an oven at controlled temperatures. The result is a compact, durable layer with a high-quality finish.
How powder coating works
Operational stages
01
Surface preparation
The sheet metal is thoroughly degreased to remove impurities, oils and residues. A clean surface is essential to ensure that the powder coating adheres perfectly.
02
Washing and protective treatment
After degreasing, the sheet metal is washed with demineralised water (DEMI water), which prevents the formation of streaks or contamination.
This is followed by a protective salt spray treatment, which helps to increase corrosion resistance and improve the durability of the coating, particularly in outdoor or harsh environments.
03
Powder application
Powder coating is applied using electrostatic spray guns, which charge the particles and ensure they adhere perfectly to the metal surface. This process guarantees even coverage with no
04
Curing and polymerisation
The coated parts are placed in a temperature-controlled oven (between **160°C and 200°C**) for curing and powder polymerisation. During this stage, the coating melts and bonds to the surface, forming a compact, strong and durable layer.
The advantages of powder coating
for sheet metal
Mechanical and chemical resistance: the coated surface is protected against impacts, scratches, weathering and harsh substances.
High-quality appearance: smooth, gloss or matt finishes, available in a wide range of colours and textures.
Even coating: thanks to electrostatic application, the powder adheres perfectly even in complex areas.
Environmental sustainability: no VOC solvents, reduced waste and a recyclable process.
Corrosion protection: also ideal for outdoor environments or industrial applications.
