Metal Powder Coating
Modern technology for durable and aesthetic surface treatment.
Powder coating (Komaxit coating) is among the most modern and reliable methods of surface treatment for metal parts. It is a technology that is an indispensable part of both the engineering and construction industries today.
The result is a continuous, hard, and extremely durable layer with a long lifespan and high aesthetic quality.
How does powder coating work?
Powder paint is applied electrostatically to a grounded metal object. The powder particles are electrically charged, creating an electrostatic attractive force between the powder and the coated part.
This force ensures an even application of a dry powder layer over the entire surface.
After application, curing follows in a baking oven at a temperature of approximately 170 – 200 °C for a precisely determined time (usually 10 – 25 minutes). During this process, the powder melts, chemically cross-links (polymerizes), and forms a solid, compact surface.
Methods of powder charging
Electrostatic (Corona) Charging – "STATIC"
The powder passes through a high-voltage electrostatic field, where it acquires an electrical charge. This method is the most commonly used and allows for precise control of application.
Tribostatic (Friction) Charging – "TRIBO"
The electrical charge is generated by the friction of powder particles against an insulator. This method is used in specific applications and allows for uniform coverage even of more complex shapes.
Resulting coating properties
A correctly applied and cured powder coating provides:
• high corrosion resistance
• chemical resistance
• resistance to impact and mechanical damage
• abrasion resistance
• flexibility of the surface layer
• UV stability
Such a treated surface is also suitable for products coming into contact with drinking water, children, or food (depending on the type of paint used).
Aesthetic possibilities
Powder coating allows for a wide range of RAL shades and surface finishes:
• smooth glossy or matte surfaces
• fine or coarse textures
• metallic and special effects
We will adapt the color and structure to your requirements and the intended use of the part.
Why is powder coating advantageous?
Compared to conventional wet painting, powder technology provides:
• higher mechanical resistance
• more uniform layer thickness
• an ecological process without solvents
• longer lifespan of the surface treatment
The result is a surface that not only looks good but, above all, reliably protects the metal core.
