Powder coating is an advanced, environmentally friendly technology for applying a protective and decorative finish to metal products and structures. It is a modern, durable alternative to traditional liquid paints, providing a perfectly even layer, corrosion resistance and a high-quality appearance.
Thanks to its unique composition and thermal curing technology, powder coating reliably protects parts even under intensive use.
What is powder paint and how does the technology work?
Powder paint is a finely dispersed mixture that consists of:
- Resins (form a strong, monolithic protective framework);
- Pigments (provide rich, stable colour);
- Curing agents and functional additives (responsible for curing and elasticity).
Stages of the powder coating process:
- Surface preparation: cleaning, degreasing and phosphating for maximum adhesion.
- Application: the dry powder is sprayed onto the metal with an electrostatic or tribostatic gun.
- Curing: the product is placed in a special oven where, at high temperature (160–200 °C), the paint melts and forms a continuous baked-on coating.
Types of powder paint: how to choose the right formulation
Depending on the operating conditions, different types of polymer coatings are used:
| Coating type | Key properties | Applications |
|---|---|---|
| Epoxy | Excellent adhesion, high chemical and corrosion resistance. | Interior structures, equipment, machine parts. |
| Polyester | Resistance to UV radiation, fading and precipitation. | Façade elements, outdoor furniture, car wheels. |
| Epoxy-polyester | Combined formulations with high mechanical strength and aesthetics. | Metal furniture, household appliances, shelving. |
Aesthetics and textures: RAL colours and visual effects
Powder paint opens up endless design possibilities. The coating can be adjusted both by gloss level and by texture:
- Gloss level: matt, semi-matt, semi-gloss, gloss, high gloss.
- Surface texture: smooth, fine texture, coarse texture.
Tip: Textured coatings (fine and coarse texture) are excellent at hiding small defects, roughness and unevenness left after the metal's initial processing.
Advantages of powder coating metal products
- Maximum durability: the coating resists corrosion, rust, mechanical abrasion and temperature changes.
- Thickness control: a layer of 30 to 250 µm can be applied in a single cycle without runs or sagging.
- Environmental friendliness and safety: the formulation contains no toxic solvents, and leftover powder is reused in the spray booth.
- Coating complex shapes: an even layer covers non-standard parts, welds and hard-to-reach areas.
Powder coating of metal and aluminium furniture
The technology is especially popular in the production of metal, aluminium and loft-style furniture. Powder coating is used for table and chair frames, garden furniture sets, shelving and retail equipment.
Even with daily outdoor use or in high-traffic interiors, the furniture keeps its attractive, premium look for many years.
