What is powder coating and what are its advantages?
Powder coating is applying a polymer powder to a metal surface, followed by baking in an oven at 160–200°C. This forms a monolithic coating without runs or bubbles. Advantages: high hardness and impact resistance, corrosion and chemical resistance, wide RAL color range, eco‑friendliness (no solvents).
What colors and textures are available?
We work with the full RAL color spectrum (over 200 shades), as well as metallics, hammered, and orange‑peel textures. Gloss levels – matt, semi‑matt, glossy. For non‑standard colors, powder can be ordered to a specific RAL code. Coating samples are available upon request.
How much stronger is powder coating than ordinary paint?
Powder coating significantly outperforms liquid paints in mechanical strength: pencil hardness – H–2H, impact resistance – at least 50 kg·cm per Gardner method. The coating does not crack on bending, is resistant to salts, alkalis, oils. Service life under normal conditions – from 15 years without loss of decorative properties.
Which metals can be powder coated?
Powder coating is applied to steel (including galvanized), stainless steel, and aluminum. Before powder application, the metal undergoes mandatory preparation: degreasing, phosphating, or sandblasting – this ensures adhesion and durability of the coating.
Is special surface preparation required before powder coating?
Yes – surface preparation is a mandatory step, largely determining the quality of the coating. We perform degreasing, and if necessary, sandblasting or phosphating. If the product comes to us after welding, we first clean the welds and eliminate surface defects.
What is the maximum coating thickness and part dimensions?
Standard powder coating thickness at our facility is 60–120 µm; multiple layers can be applied if needed. Maximum part dimensions depend on our coating booth and curing oven – please check with our managers when placing an order, we will answer promptly.
Can you coat a product that already has press‑fit fasteners installed?
Yes, that is our standard practice. Before painting, all threaded holes and fasteners are covered with protective plugs that shield the threads from powder. Upon request, we additionally mask specific areas of the product that should not be coated.
