Uniform sealing of aluminium surfaces

Can one speak of a lotus effect?

Can one speak of a lotus effect?

In principle yes: The lotus effect acts like a seal on the surface. SILA-COAT® 5000 does too.

The process

SILA-COAT® 5000 is primarily a process for sealing aluminium alloys. The surface treatment takes place in a 3-stage process:

  1. Pretreatment, tailored to the aluminium material
  2. Conversion treatment
  3. Sealing with an electrophoretic dipping paint
  • Properties

    The regularly formed network structure of the paint dip coating seals the surface and levels it. The result is very uniform coatings, even on complex components with internal surfaces such as oles or cavities.

    Sealing the surfaces of aluminium alloys with SILA-COAT® 5000 increases the corrosion resistance and significantly increases the alkali resistance. SILA-COAT® 5000 is biocompatible and safe for use with food according to FDA regulations. The coating shows good chemical resistance and corrosion resistance.

    Process variants of SILA-COAT® 5000 result from the choice of the respective intermediate layer. This also determines the colour of the coating. A conversion layer produces a gold-coloured final layer. Technical anodising or hard anodising (HART-COAT®) as an intermediate layer changes the colour appearance towards metallic grey or black.

  • base material

    The SILA-COAT® 5000 process is suitable for wrought aluminium and cast aluminium alloys. We are happy to check other base materials for suitability for coating on request.

  • Application

    Due to its properties, paint dip-coating with an anodised intermediate layer, where required, is applied where aluminium components have to be cleaned with alkaline or acidic media: for example, food processing, packaging systems, laboratories, medical technology or gastronomy. Especially inaccessible parts such as cavities and holes can be uniformly provided with a smooth layer. In addition, the good dielectric strength combined with high corrosion resistance makes SILA-COAT® 5000 interesting for the coating of electrical components.

    SILA-COAT® 5000 is therefore particularly suitable for applications in the following sectors: general mechanical engineering, plant engineering / plant construction, automotive industry, food industry, medical technology, packaging industry.
