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.
