The surfaces of aluminum alloys and anodizing layers are sealed with the aid of a dipping varnish. Very even layers are created, even on complex components with internal surfaces such as drill holes or cavities. Sealing the surface with clear coat increases corrosion resistance and significantly increases alkali resistance.
SILA-COAT® 5000 is a high-performance aluminum surface treatment with clear coat applied to the surfaces of aluminum alloys with the aim of sealing them. The coating, which is applied by anodic dip coating, is usually transparent and can be used on aluminum as well as steel materials. In addition, several layers can be combined to increase certain positive properties such as resistance or electrical insulation. SILA-COAT® 5000 is created in a three-step process:
Pre-treatment tailored to the respective aluminum material
Sealing by means of electrophoretic dip coating
SILA-COAT® 5000 increases the surface’s resistance to corrosion, while significantly enhancing its alkali resistance. The dip coating’s regular network structure seals and levels the surface.
Aluminum surface treatment with SILA-COAT® 5000 produces very uniform coatings on complex components with interior surfaces such as drillings and cavities. This type of coating results in good resistance to chemicals and corrosion.
The process can be varied by the application of different interlayers, which also define the color of the coating. A conversion layer creates a golden surface, whereas interlayers created with HART-COAT® hard anodizing and technical anodizing change the color impression towards a metallic gray and black.

Our SILA-COAT® 5000 process creates surface coatings for aluminum parts, such as wrought and cast aluminum alloys. Upon request, we will be happy to check the coatability of other base materials.
fields of use
Good dielectric strength and high corrosion resistance make SILA-COAT® 5000 interesting when it comes to electrical components. When applied to such components, this coating solution prevents the formation of oxide layers. SILA-COAT® 5000 anodic dip coating (also referred to as ADC) can also be used whenever aluminum components need to be cleaned with alkaline media. Concrete fields of use include packaging plants, laboratories, medical technology and gastronomy. Dip coating can be used to apply even and smooth layers to component areas which are difficult to access (e. g. cavities or drillings). Where required, an anodized interlayer should be applied as well.
SILA-COAT® 5000 increases the corrosion resistance of aluminum components, while clearly enhancing their dielectric strength. The surfaces are leveled so that it is also possible to deposit even layers in cavities and drillings.
The mere SILA-COAT® 5000 layer is transparent. It is the application of an interlayer that determines the final color. A conversion layer creates a golden surface, whereas interlayers created with technical anodizing and HART-COAT® hard anodizing change the color impression towards a metallic gray and black.

Mit 40 Jahren Erfahrung in der kontinuierlichen Veredelung von reel to reel können Sie sich auf Aalberts surface technologies verlassen, um innovative Lösungen zu finden. Unser Service umfasst Trommelgalvanik, kontinuierliche selektive Galvanik und Gestellgalvanik.
Fast alle metallischen Grundwerkstoffe können mit unseren selbstentwickelten und patentierten Verfahren durch Oberflächenbeschichtungen in ihren Eigenschaften optimiert werden, egal ob sie besonders hart, glatt, verschleißfest oder korrosionsbeständig sein sollen.
We offer all types of heat treatment processes. Our facilities are closely interlinked in terms of logistics, which means that all processes are available to you. For a complete list and description of heat treatment technologies please select the button.
Hot isostatic pressing (HIP) is used to eliminate porosity. Do you need high mechanical durability and insensitivity to high temperatures for solder joints? We at Aalberts surface technologies offer the solution through brazing.
Polymer coatings can be applied to a wide variety of base materials and offer long-lasting protection. They are particularly well anchored mechanically to the substrate. Additional enhancement layers allow non-stick coatings to be combined with improved sliding properties and/or high wear resistance.
With 40 years of experience in continuous reel to reel finishing, you can depend on Aalberts surface technologies to find innovative solutions that other companies might say are impossible. Our service includes barrel plating, continuous selective plating and rack plating.
Almost all metallic base materials can have their properties optimised by surface coatings using our proprietary and patented processes, regardless of whether they should be particularly hard, smooth, wear-resistant or corrosion-resistant.
