Painting / varnishing

BWB Oberflächentechnik varnishes components made from aluminium, steel, wood and various plastics to protect them from weathering and corrosion, and to give them a high-quality, durable surface finish.
It also has a variety of chemical and electrolytic pre-treatments that additionally protect the components.
BWB's varnishing plants are certified as top-quality suppliers for leading manufacturers in the fields of aviation, automotive, rail-car and mechanical engineering and architecture.

Pre-treatments

Cleaning and de-greasing

The corrosion-resistance, adhesiveness and quality of a varnish coating are determined by the subsurface, which needs to be suitably pre-treated and cleared of greases, oils, separating agents, dirt and layers of corrosion:
Rinsing
Chemical de-greasing
Pickling

Mechanical pre-treatment

These processes mechanically remove corrosion products and impurities:
Sandblasting
Bead blasting
Compression blasting
Sanding

Chemical pre-treatments

Chemical pre-treatments form conversion coatings that serve as an optimum primer for the varnish, while also offering a high degree of protection against corrosion:
Phosphating
Chromating
Chromiting (chromium-free, Surtec 650)
Chromic-acid anodising
Passivation
Pre-anodising

Processes

Varnishing with maximum surface purity

BWB's paint shops boast state-of-the-art infrastructure. BWB Oberflächentechnik has also made perfectly finished surfaces an insiders' tip for contemporary artists all over the world.

A variety of special varnishes

Our varnishes and colours range from special varnishes to highly weatherproof, self-cleaning fluoropolymer paints, to every hue on the RAL and NCS colour spectrum. And when it comes to architecture, BWB also has a colour system that reproduces the shades of the anodising colour chart in a wet finish.

Technical specifications for our facility:

Length 800 cm
Width 300 cm
Height 300 cm

 

The processes are combined as necessary on a case-by-case basis to obtain the ideal outcome for the respective application. As the effectiveness of the pre-treatments is not permanent, the varnish coating is applied straight after the pre-treatment.
