Powder coating

A durable and cost-effective coating methods particularly for metals


Metal surfaces are typically powder coated. First, the powder is sprayed onto the treated surface using compressed air. An electrostatic charge attaches the powder to the surface, and once the powder is cured in an oven, the workpiece will have a finish that is very resistant to wear and impacts. Any scratches and scuff marks that may occur during installation can be easily removed with car wax or fine grit water sandpaper and wax. Powder coating can last for up to 50 years!

Powder-coated materials

Powder coating is best suited for metals, such as steel, aluminium and galvanised (including hot-dip galvanised) steel. However, the technological advancements in the field have enabled the coating of many other surfaces, with certain reservations.

Linjateräs powder coats all common metals!

STEEL

Steel is a popular and fully recyclable material. However, oxygen and moisture subject it to corrosion. Therefore, it should be protected against corrosion.
Stainless steel is a suitable material particularly for wet and humid conditions. Weather resistance makes it a widely used material in facades, for example.

AlumiNIUM

Aluminium is more expensive but considerably lighter compared to stainless steel. This makes it a commonly used material particularly in the construction and transport industries. Its typical applications include wall and window elements and glazed structures, facades and covers, wall panels and partition walls, ventilation and heating equipment and boats, ships, trains, cars, bicycles, airplanes and space shuttles.

Galvanised steel (including HDG steel)

Zinc coated, or galvanised, steel is more affordable than stainless steel. However, its surface is not as shiny or smooth, and the material is more difficult to clean. Powder coating improves the visual appearance of the zinc coating. Moreover, powder coating extends the life of galvanised steel – which, naturally, applies to all other powder coated materials as well.

As hot-dip galvanised steel withstands salt water, the material is commonly used particularly in the marine industry. Its other applications include streetlamps, railings and fences.

Other materials

Modern technology allows us to powder coat three-dimensional objects. Furthermore, we can powder coat wood, plastic and composite products with certain reservations. Contact us for more information!

We will help you choose the correct coating powder

Coating powder is selected according to the application in question. Harsh environmental conditions and hard physical or chemical stresses naturally set stricter requirements for coating powder compared to indoor applications. Our competent staff will gladly help you choose the right coating powder and answer any questions you may have about colour availability or compatibility.

The most common powder coating binding agents

Epoxy powders

Epoxy powders are suitable for painting metal industry products that are stored indoors and require chemical resistance, such as the ability to withstand acids and alkalis. Epoxy powders are well suited for special applications in the metal and chemical industries.

Epoxy polyester powders

Epoxy polyester powders are best suited for indoor objects that require mechanical durability. Furthermore, epoxy polyester powders are a cost-effective choice as their short coating time results in a lower cost.

Polyester powders

Polyester powder is a very common powder material because it is suited for outdoor as well as indoor use. Polyester powders can be used, for example, for powder coating metal industry products for outdoor applications, where the requirements include good weather resistance and anti-yellowing properties in heat and UV light. For demanding conditions, choose a corrosion-resistant painting system compliant with the SFS-EN ISO 12944-2 environmental standard.

Polyurethane powders

Polyurethane powders are suited for products whose surface must be very resistant to mechanical and chemical wear. Polyurethane powders provide good UV protection, which makes them an excellent choice for outdoor sites. Their applications include forest and field machinery, bicycles and other vehicles. They are also used in anti-graffiti paints.

Special paints

Antibacterial paints

Antibacterial paint destroys quickly any bacteria and microbes that occur on the surface. Surfaces coated with antibacterial paints pass even the strictest hygiene criteria. Their common applications include kitchens, hospitals, laboratories and other research facilities.

Anti-graffiti paints

Anti-graffiti paints can withstand even strong solvents without damaging the paint coat. They are, therefore, used in order to make it easier to remove the potential defacement of the surface.

Super Durable coating powders

Super Durable coating powders are extremely resistant to varying weather conditions, UV radiation and mechanical stress. This makes them well suited for the construction industry, parks and fences, and the ship, train and car industries.

Lacquers

There are also coloured powder lacquers available.

Heat resistant paints (silicone paints)

Silicone powders are used in products whose surfaces must be able to withstand higher than normal temperatures. Their typical applications include sauna heaters, barbecue grills, exhaust pipes and furnaces.

Primers, zinc and epoxy primers

Zinc improves corrosion resistance. Zinc-based primers are particularly suited for objects designed for long-term use in conditions where harsh environmental conditions might otherwise impact the service life.

Conductive coating powders (ESD)

Conducting coating powders, or ESD coating powders, are antistatic. They are especially suited for spaces where static electricity may cause issues. ESD paints are used, among others, in the electronics industry.

Surface types

Powder coating can create various effects on the surface, including coarse or fine textures. We also offer a range of different pearlescent effects. One or more of these effects can be used with any hue!

Hammer paint

Hammer paint is a metal paint designed for indoor and outdoor use. It can also be used on wooden surfaces, with some reservations. As the name implies, a hammer painted surface looks like hammered enamel, and it has good anti-corrosive properties.

Texture paints (sandpaper and orange peel effect)

Texture paints can be used for creating intriguing effects on the surface. The can be used in outdoor as well as indoor applications, and they are generally used in electronics and furniture.

Metallic and pearlescent paints

We offer a wide range of metallic and pearlescent paints. Contact us for more details!

Gloss levels

  • Glossy 85–95%
  • Semi-glossy 65–80%
  • Matte 20–30%
  • Super matte 1–5%

Nearly all gloss levels can be achieved upon separate request!

Wide range of colours

    • Various colour options
    • RAL and RR colours (mostly in stock)
    • NCS and other special colours
    • Pearlescent and texture surfaces

      We can provide details on colour compatibility upon request.

      Powder coating gives the product

      a finished look

      No paint runs

      As opposed to wet painting, powder coating has no paint runs. Furthermore, powder coating rounds the object’s sharp corners. A smooth, even and shiny coat gives the finished product an impressive look.

      Eco-friendly coating

      Coating powders do not contain any chlorinated hydrocarbons or organic solvents, so they do not create VOC emissions that would impact the atmosphere. Furthermore, the overspray material is recovered during coating and reused, so nearly 100% of the coating powder is used.
