Compendium
of finishes
Finishes for almost every application
OBO offers a wide range of finishes
for a wide range of materials that
can be used on its product solutions. The function of these finishes
ranges from corrosion protection –
galvanised finishes are an example
– all the way to decorative powder
coating. We have gathered together
all the different kinds of finish in this
Compendium. It contains technical
descriptions of their properties, as
well as information about the kind
of places they can be used. Actual
photographs of each finish present
as accurate a picture of them as
possible.
Please note that for technical reasons, the colours and gloss levels
may come out slightly differently in
print.
Our Customer Service is available
at any time to answer any questions you may have about finishes and materials.

OBO’s ultra-modern powder coating system has put an end to long
periods of waiting after surface
treatment. Powder lacquers harden
immediately after baking, and parts
can be processed.

New application technique
This system can accommodate products up to six metres long, such as
cable ladders. In the first stage, pretreatment, almost any kind of metal
(apart from coloured sheeting such
as brass or copper) is treated using
water and chemical additives. Parts
are then put in the dryer, before
being given a powder lacquer coating by means of an electrostatic
process in the powder cabin. This
new application technique allows
more powder types to be used,
enabling products to be treated on
their surfaces to withstand extremely rough conditions. The choice
of surface textures is also diverse;
rough, medium-rough and smooth
surfaces are all available.
Fast and eco-friendly
Thanks to our new quick-change
cabin, colours can be changed
in just ten minutes instead of two
hours. This technology, and the solvent-free paints used, is also much
more ecofriendly than conventional
types of paint. Used water from the
preparation system is completely
recycled in a vacuum evaporator
and used again.

Powder coatings
Diverse, beautiful, tough
Surface coatings using powder
lacquer offer a wide range of possibilities. They can turn a standard
product into a custom solution tailored precisely to your colour and
6
functional requirements. Colour and
texture provide a decorative exterior, while the properties of the paint
make the product highly resistant to
chemicals, well protected against
corrosion and excellently insulated.

Metallic powder coatings
Metallic coatings stand out on account of their brilliant finish, visual
depth and variations in colour, depending on which angle you look at
them from. Unlike standard colours,
metallic finishes change in the light,
giving them much more vitality.

Rough, medium-rough or smooth –
numerous effects can be achieved
using powder lacquers. They help
you to adapt product finishes into
the environments in which you wish
to use them.

Powder coatings
Antibacterial finishes
Unique and safe. A specially developed material added to the powder
lacquer destroys harmful bacteria.
The effect of this additive remains in
the powder lacquer for many years,
24
making the coated surface permanently antibacterial. This material is
especially useful on products such
as ducting installed in medical and
food industry areas.
Powder coatings
Powder-coated finishes
with special properties
Highly scratch-resistant and
abrasion-resistant
Powder coatings don’t just offer
diverse decorative possibilities. By
using the right paints and treatment
methods, surfaces can be given
tough characteristics such as resistance against scratching and abrasion. They can also be made highly
resistant to chemicals.
25
Powder coatings
Special corrosion protection with
an emphasis on colour
Protection against corrosion is needed not only outdoors, but also on
products used in humid indoor environments. The right powder lac-
26
quer coating not only provides that
protection, but also allows you to
design products that fit into your environment. This is the perfect symbiosis of function and design.

Polyurethane powder lacquer
Polyurethane powder lacquers offer
outstanding resistance to weather
and chemicals. That makes them
perfect for coating indoor and outdoor elements. Because they are
highly resistant to scratching and
also very elastic, these paints are
the ideal coating for use in agriculture and shipbuilding, as they can
stand up to lots of rough treatment.

Epoxy-polyester powder lacquer
Indoors and out, epoxy-polyester
powder lacquers combine high levels of protection with dependable
quality and elegant looks. Superb
physical properties and high flexibility indoors mean there are many
ways you can use them in upmarket applications. Out of doors, these paints provide lasting protection
against environmental influences,
without losing colour or gloss.

Transfer process
Discover unimagined design
possibilities
A special transfer process enables
us to apply a range of stunning decorative finishes. This process can
be used on Rapid 80 GS (steel) as
well as Rapid 45 and Rapid 80 GA
(aluminium) device installation trunking. The unique designs are especially effective on ISS service poles.
30
The patterns are stable under light,
and impact-resistant, meaning they
last longer than standard powder
lacquers. This allows you to create
individual wall designs with no limits
to your imagination.

Galvanised finishes
Special coating thicknesses
OBO offers galvanised finishes in
a range of special coating thicknesses for specific requirements.
Thicker layers of zinc can be applied, for example, to cable trays,
cable ladders, brackets and sus-
34
pended supports in power stations.
These special coatings can also
protect components used in wind
power equipment, which is especially vulnerable if installed in saline
environments near to the sea.

Indoors or out, in aggressive atmospheres or highly hygienic environments, whatever your requirements,
OBO offers the ideal surface finish
and material for your cable support
system. OBO cable support, wiring
routing and underfloor systems are
made of high-grade sheet steel and
steel wire, and can be supplied in
a variety of finishes. Different methods of treatment and coating provide just the corrosion protection
you need, tailored to the use you
have in mind.
35
Galvanised finishes
At its Menden facilities, OBO operates one of Europe’s most advanced hot galvanising plants. The zinc
bath at the plant is 7.5 metres long,
3.5 metres deep and 1.4 metres
wide, and contains up to 260 tons
36
of zinc. The latest filter technologies and heat exchangers ensure
that the production process uses
resources such as gas, electricity,
zinc and acid sustainably.
Galvanised finishes
Welcome to one of Europe’s
most advanced galvanising
plants
Hot galvanising means applying
a metallic zinc coating to iron or
steel. Individual parts, such as those used for electrical cable trays,
are immersed in molten zinc at 450
degrees Celsius. A resistant alloy
forms which provides protection
against corrosion. OBO’s unique
way of treating galvanised goods,
called ‘passivation’, prevents the
formation of white rust.

Appropriate corrosion protection
Corrosiveness categories
Corrosion can bring about significant losses, and can even cause
technical systems to break down.
Preventing and reducing corrosion
is therefore an important part of
protecting steel components. The
DIN EN ISO 12944-2 standard carefully defines corrosiveness categories. It divides atmospheric ambient conditions into a total of six
different categories. The following
parameters determine the level of
corrosion and the speed at which
it happens:
• Relative humidity
• The risk of condensation
• The concentration of impurities that cause corrosion
Special requirements
How long a cable routing system
lasts depends upon the environment in which it is situated. If a
cable support system is installed
outdoors, then the best possible
materials and the maximum protection against corrosion are required.
This becomes especially challenging in aggressive atmospheres,
such as those found in the chemical and petrochemical industries.
Systems are also permanently
under attack in extreme weather
conditions and near to the sea. It
is very important to know the environmental influences involved when
selecting the materials and surface
finishes used.

Metallic effects
Materials such as anodised aluminium and brass can be used
to achieve a number of colourful
effects. Anodising refers to the
electrical oxidation of aluminium.
This creates an extremely hard and
scratch-resistant surface which
offers protection against corrosion. The material’s metallic appearance is preserved. An anodised
layer can be coloured, and these
colours are then highly resistant to
abrasion and chemical influences.
The different shades of brass are
dependent on the level of copper in
the material. They are often golden
in colour, but can also be anything
from brown to reddish, or from light
yellow to almost white-yellow.
