Carbon black pigments are used in adhesives in order to colour the
adhesive compound deep black, to make it conductive and to make the material
ageing resistant to UV light. There are, in particular, very high demands on
the adhesives and the carbon blacks in the field of high-tech adhesives and in
the automotive sector.
The paints and varnish industry imposes several requirements on the
carbon black pigments. Lamp black types are frequently used for tinting paints
and primers. Furnace and channel blacks are used for coatings of higher
qualities.
Due to our large product range, we are able to provide you the right
type of carbon black for all requirements.
Pigment Carbon Black play an important role in the field of printing
inks. Owing to the large number of carbon black types available, that are
different in structure, particle size and surface chemistry, there are
optimized carbon black pigments for any formulation and all printing methods.
Carbon black pigments can be used to colour plastics in the requested
shades of grey and black. Apart from this, the use of carbon black pigments
minimizes the photo-oxidative degradation of plastics caused by UV light. An
antistatic finish or electrical conductivity of the plastics can be achieved by
means of a highly structured furnace carbon black or special high-performance
carbon blacks. Special requirements imposed on plastics coming into contact
with food can be met by special carbon black pigments. These grades are
characterized by particularly low PAH values and a low degree of impurity.
Carbon black pigments are widely used in metallurgical applications:
The pore density of refractory materials is reduced. In addition, Carbon
blacks have the effect of reducing slag which improves the life cycle of the
materials.
Carbon blacks are used for special alloys as casting powder and cover
powder which allows regulating the lubricating effect, the thermal insulation
and a controlled release of slag formers.
The structure and particle size are very important for these particular
applications. In special cases, it is an advantage to use carbon blacks with
oxidic surfaces, i.e. channel blacks or non-oxide furnace blacks.
For the colouring of paper, it is recommended to use pre-dispersed
carbon blacks in liquid preparations. For nuanced mass colouration of pulps or
for film coating, we offer appropriate preparations based on furnace black
pigments or channel blacks featuring a particularly small particle size that
provides for a special colour depth. For electrical conductivity purposes, we
offer a series of special carbon blacks and preparations adapted to such
requirements.
Anionically or cationically stabilised liquid preparations are available
as an option.
Adjusted
liquid preparations qualify for the colouring of technical textiles, in
particular fleeces. Depending on the requirements, they provide for a
purposeful increase in UV or IR absorption, conductivity or just a particularly
high colour depth. A wide range of available additive systems enables us to
adapt the compatibility with the aid of binding agents in order to avoid
system-related agglomerations and incompatibilities.
