Electrophotography
We have been a trusted supplier to the electrophotography industry for more than 30 years.
Our global reach enables us to partner closely with our customers to meet the highest standards for performance, quality and service. We offer a wide range of silica external additives and carbon black pigments for toners.
To give toner manufacturers maximum flexibility in designing their formulations, we offer the widest range of silica additives for toners of any major manufacturer. Our portfolio includes fumed silica, colloidal silica and silica-polymer composite materials with primary particle sizes ranging from 8 nm up to 200 nm. Combined with a variety of available hydrophobizing treatments, these offerings allow for the controlled tuning of performance characteristics such as tribocharge, freeflow and spacing for consistent print quality across a range of conditions.
Additionally, we offer carbon black pigments for use with polyester and styrene acryclic resins in chemical, conventional and liquid toners. Our products enable black toners to achieve high image density and tribocharging for outstanding print quality.

Silica Additives for Toners
A breakthrough material for electrophotography applications comprised of hydrophobic silica and polymer in spheroid particles of approximately 100 nanometers in diameter. The shape and size of these silica composite particles have been engineered to prevent embedding, migration and separation from the toner surface.
A large particle silica product designed to act as a spacer in toner formulations where maintaining image quality over long print runs is desired. It is a fumed silica with a hexamethyldisilazane (HMDZ) surface treatment that provides very good tribocharge and free flow.
A large particle silica product designed to act as a spacer in toner formulations where maintaining image quality over long print runs is desired. It is a fumed silica with a hexamethyldisilazane (HMDZ) surface treatment that provides excellent tribocharge and free flow. It is also post-processed to ensure a narrow distribution of agglomerate particle sizes that results in a more homogeneous charge distribution, fewer print defects and enhanced free flow.
A large particle silica product designed to act as a spacer in toner formulations where maintaining image quality over long print runs is desired. It is a fumed silica with a polydimethylsiloxane (PDMS) surface treatment that provides excellent transfer efficiency and good tribocharging.

A colloidal silica powder with an alkylsilane surface treatment, specially designed for toner formulations where there is a need for a spacer particle that provides excellent print durability and good tribocharging even under humid conditions. Compared to equivalent fumed silica products, the narrow particle size distribution results in a homogenous charge distribution to enable outstanding print quality.
Specialty Carbon Blacks for Toners
A specialty pigment designed to impart high gloss and high jetness in printing inks and polyvinyl chloride (PVC) compounds, such as consumer electronics cable jacketing.
A low structure specialty carbon black pigment that is designed to impart high gloss and high jetness in printing inks, coatings and electrostatic toner applications.
A low structure specialty black pigment designed to impart high gloss and very good color strength in lithographic gloss inks.
