Frequently asked questions about powder coating
General questions about powder coating
What is powder coating?
Powder coating is a durable finishing technique in which a powder is applied electrostatically to a metal surface and then cured in an oven. This results in a strong, wear-resistant and corrosion-resistant coating.
How does powder coating work?
Powder coating is a process in which a dry powder is applied electrostatically to a metal surface and then cured in an oven to form a strong, even protective layer.
First the parts are thoroughly cleaned and degreased to ensure optimal adhesion. The powder is then applied with a spray gun, and adheres evenly to the surface thanks to the electrostatic charge.
The pieces then go into a stoving oven where the powder melts and flows out into a durable coating. After cooling, a wear-resistant and corrosion-resistant finish with a long lifespan is created.
What is stoving?
Stoving is the curing of powder coating in an oven. After the powder has been applied, the metal parts are heated to a certain temperature, causing the powder to melt, flow out and form a closed, hard layer of paint.
This process creates a durable finish that adheres strongly to the metal and protects against corrosion, wear and weather conditions. Stoving is therefore an essential part of the powder coating process and largely determines the quality and lifespan of the end result.
What are the advantages of powder coating?
Powder coating offers excellent protection against corrosion, scratches and weather conditions. It is also low-maintenance, more environmentally friendly than traditional paint systems and available in a very wide range of colours and finishes.
Which materials can be powder coated?
Powder coating is mainly applied to aluminium. It is used for profiles, structures, machine parts, automotive components and household appliances.
How environmentally friendly is powder coating?
Powder coating is an environmentally friendly process because it contains no solvents and causes virtually no harmful emissions. Excess powder can also largely be recovered.
Why is pre-treatment important?
Correct pre-treatment ensures optimal adhesion of the coating and increases the durability and corrosion resistance of the end product.
How long does a powder coating last?
The lifespan depends on the application and environmental factors, but a properly applied powder coating can offer protection for decades.
Do you work for both small and large projects?
Yes, we handle both small series and large industrial production orders as well as custom projects.
Questions about powder coating applications
In which sectors is powder coating used?
Powder coating is used in a wide range of sectors such as construction and window profiles, industrial construction, machine building, automotive and the production of household appliances. Each sector has different requirements in terms of protection, finish and durability.
Why is powder coating so widely used in the construction sector?
In the construction sector, powder coating is mainly applied to window and door profiles, facade systems and balustrades. The main reason is the combination of aesthetics and durability: it offers long-lasting protection against weather conditions and retains its colour and appearance for many years.
What are typical applications in industry and machine building?
In industrial applications and machine building, powder coating is mainly used for functional parts such as machine frames, protective covers, technical housings and structural parts. The focus here is on wear resistance, corrosion protection and a low-maintenance finish.
Which finishes are possible per application?
Depending on the application, matt, satin or glossy finishes can be chosen. Textured paints, metallic effects and specific project colours are also possible. The right finish is matched to both functional and aesthetic requirements.
How is it determined which coating is suitable for an application?
The choice depends on factors such as the environment (indoor or outdoor), load, aesthetic wishes and expected lifespan. On this basis the right combination of pre-treatment, powder quality and finish is determined.
Questions about powder coating finishes
Which colours are possible with powder coating?
Powder coating is available in a very wide range of RAL colours and project colours. This allows every finish to be matched perfectly to architectural plans, corporate identities or specific customer requirements. Special custom colours are also possible for larger projects. Find out more about our finishes here.
What is the difference between matt, satin and gloss?
Matt finishes have a calm, modern look without reflection and hide small imperfections well. Satin sits between matt and gloss and offers an elegant, timeless look with limited reflection. High gloss gives a sleek and striking result with strong light reflection, often used for decorative applications.
Which finish is most suitable for outdoor use?
For outdoor applications, durable polyester coatings are often used in combination with matt or fine-textured finishes. These offer good resistance to UV radiation, weather conditions and colour fading.
Which textures are possible?
In addition to colour and gloss, the texture of the coating can also be adjusted. Commonly used textures are fine texture and coarse texture. These often increase scratch resistance and give the surface a more robust look.
Frequently asked questions about our quality
What determines the quality of powder coating?
Quality is determined by various factors such as the pre-treatment of the material, the powder quality used, the application, curing in the oven and the quality control afterwards. Each of these steps is essential for a durable end result.
How durable is powder coating?
Powder coating is very durable and offers strong protection against corrosion, UV radiation, wear and chemical influences. Depending on the powder quality chosen and the environment, a coating can last many years without loss of quality.
What does Qualicoat mean for quality?
Qualicoat is an international quality label that guarantees that the entire powder coating process meets strict standards. This includes pre-treatment, coating thickness, adhesion and corrosion resistance. It gives customers extra certainty about the durability and consistency of the end product.
What is Qualicoat Seaside?
Qualicoat Seaside is an extension of the standard and is specifically intended for applications in coastal areas or environments with high corrosion pressure. It offers even higher resistance to salt, moisture and aggressive weather conditions.
