high-performance functional coating - a microscale protective layer for long-lasting surface finishing
what does “high-performance functional coating” mean?
Anodically applied dip coating reliably protects metallic surfaces from corrosion and chemical agents. It forms a relatively thin and uniform layer, even on complex components with internal surfaces, such as bores, cavities, or undercuts. The SILA-COAT® coating is transparent and complies with current legal regulations.
protection for metallic surfaces with SILA-COAT® 5000
The SILA-COAT® 5000 coating meets the highest standards for chemical resistance and corrosion protection, while also complying with the latest regulatory requirements as an environmentally friendly product. In anaphoretic dip coating, applying direct current causes the component to be coated to act as an anode. The resulting chemical reaction at the anode causes the coating (based on an acrylic resin binder) to deposit evenly on the workpiece surface. The coating must then be thermally cured at 180–200 °C.
Process Flow:
1. Pretreatment (tailored to the base material or undercoat)
2. High-performance functional coating
3. Heat treatment
The result is a uniformly distributed coating over the entire component surface. Depending on the geometry and initial surface condition, additional leveling may also occur.
properties
This is a transparent coating produced by anodic dip coating. Its primary purpose is to increase corrosion resistance and chemical resistance against various media (see data sheet for details). In addition, electrical insulation—for example, in terms of required breakdown voltages—is significantly improved. The coating is primarily used to improve the alkali resistance of aluminum alloys. However, combination coatings are also common, as duplex coatings are used to further improve resistance properties or electrical insulation characteristics in a targeted manner. Due to the transparency of SILA-COAT®, the visual appearance depends on the base material or the selected undercoat.
The advantages of SILA-COAT® 5000 at a glance:
- relatively low coating thicknesses, typically up to 25 ±5 µm
- very high resistance to atmospheric corrosion
- very high chemical resistance, particularly alkali resistance
- compensates for surface irregularities and reduces corrosion-prone weak spots
- high electrical insulation (dielectric strength)
base materials / underlayer
Coatable base materials include, in particular, aluminum alloys and steel materials; other materials should be evaluated upon request. Our anodic coatings – such as TE, HART-COAT®, or HART-COAT®-GL – as well as DURNI-COAT® electroless nickel are all highly suitable as underlayers for SILA-COAT® and can be applied directly on-site. Other base underlayers are also possible and can be coated.
applications and industries
The properties and advantages of SILA-COAT® described above enable this high-performance coating to be used in a wide range of applications. It is ideally suited for use in all areas where requirements exist—for example, for corrosion protection, chemical resistance, oxidation protection, or electrical insulation. Typical industries where it is used include:
- Machinery and plant engineering
- Automotive industry (fueling technology)
- Packaging industry
- Laboratory and analytical sector
- High-voltage technology
- Fluid technology

frequently asked questions - sealing
WHAT ARE THE BENEFITS OF THE HIGH-PERFORMANCE SILA-COAT® 5000 COATING?
SILA-COAT® 5000 increases the corrosion and chemical resistance of components and significantly improves their electrical insulation. Surface irregularities are smoothed out, and a relatively homogeneous coating structure is achieved even in cavities and holes.
CAN THE COLOR OF A COMPONENT BE CHANGED WITH A SEALANT?
The pure SILA-COAT® 5000 coating is colorless, meaning that the color appearance is determined by the base material or the underlying layer. Technically anodized or hard anodized (HART-COAT®) layers, for example, alter the color appearance toward a metallic gray or black. The gloss level of SILA-COAT® also depends on the initial roughness of the surface.
FOR WHICH BASE MATERIALS IS THE SILA-COAT® 5000 PROCESS SUITABLE?
The process is suitable for all wrought and cast aluminum alloys as well as steel materials. Other base materials will be evaluated upon request.
CAN THIS PROCESS ALSO BE COMBINED WITH OTHER SURFACE TREATMENT TECHNIQUES?
The process can be combined, for example, with HART-COAT® and DURNI-COAT® as undercoats. Other undercoats will be evaluated upon request.
