Charge Control Agents

Positive and negative CCAs for consistent toner charge stability.
Designed to optimize electrophotographic performance in black and color toner formulations.

Reliable Charge Control for Toner Formulation and Electrophotography

Charge Control Agents (CCAs) are functional additives used in the formulation of electrophotographic toner to regulate and stabilize triboelectric charge levels. Available as both positive and negative types, CCAs play a critical role in ensuring uniform particle charging, stable image density, and low background development across black and color toner systems.

By improving charge distribution and reducing environmental sensitivity, CCAs enable consistent print quality and reliable toner performance, even under demanding operating conditions.

NAGASE supplies Charge Control Agents in various chemistries tailored to customer requirements, with technical expertise and global logistics support for the printing and imaging industry.
