IRASORB BITO, the blue Indium Tin Oxide shows higher electrical conductivity and higher absorption in near infrared light compared to the yellow version, which makes it useful for coatings, inks and polymeric films.

FTO is an off-white powder with good electrical conductivity. It easily forms opaque dispersions, which are used for conductive coatings on glass as semi-transparent heating areas or for electrodes in solar cells.

The StanoStat CP range of antimony tin oxides (ATO) combine semi-conductive properties with a very light gray colouration. Compared to other ATO grades, where the blue shade is dominant, the StanoStat CP grades offer great variation in the coloring of the finished product.

The laser direct structuring process allows the manufacturing of electronic equipment directly onto a 3-dimensional polymeric or ceramic substrate without the use of a printed circuit board. Generating the electrical circuitry directly onto the polymer or ceramic part allows a high packing of electronic components and helps to miniaturize the parts. LDS additives, for example our StanoStat CP5C, are incorporated directly into the polymer. After injection molding, the resulting part is marked with a laser engraving the circuit onto the surface. This then undergoes metallisation. The metal is only deposited on the areas that have been marked by the laser. Thereafter, the components can be mounted.

StanoStat A20W is an aqueous colloidal dispersion of antimony-doped tin oxide. It may be used to produce transparent coatings with anti-static or static-dissipative properties. It may also be used for near-infrared absorbing coatings or polymers.

Irasorb CTO grades are available as powders and dispersions. In order to benefit from the superior IR absorption properties of this material, it is necessary to ensure the highest possible degree of dispersion. The CTOM10 grade offers the great advantage that it can be used directly in the extrusion or injection molding process without further pre-treatment. Formulation of Masterbatches for solar protection products is simplified.

IRASORB LM002 is a non-toxic, Sb-free combination of metal oxides designed as highly efficient Laser Marking Additive for Polymers

The StanoStat CPM range are deep blue colored antimony tin oxides with a unique set of properties. CPM oxides in bulk are aggregates, consisting of nano-sized, spherical primary particles. This allows the products to be micronised in a variety of aqueous and organic solvents to nano-dispersions, which can be integrated into highly transparent, nearly colorless coatings. CPM oxides provide a high electrical conductivity and an excellent absorption of infrared light.

IRASORB YITO, the yellow Indium Tin Oxide is predominantly used as a starting material for various processes to generate transparent conducting layers and electrodes for displays, solar cells and similar applications.
