FCA Resin-Type Charge Control Agents for Toner
The FCA series is a series of polymer charge control agents developed by our company with our unique technology.
"Unlike conventional charge control agents, FCA series products not only exhibit charge characteristics, but also provide excellent performance in areas such as safety and transparency. They can be used effectively in electrophotographic materials such as toner, carriers, and friction charging members, as well as in electrostatic painting,
and have been widely used by many customers since their market launch in 1986.
Characteristics
| Dispersibility (compatibility) |
FCA series products combine non-polar and polar components to offer excellent dispersibility (homogeneity) and compatibility with binder resins. They can be used not only with conventional grinding methods, but also in a wide range of applications such as polymerized toners (suspension method, latex method, and dispersion polymerization method), carrier coating materials, powder painting, and more. |
|---|---|
| Transparency | FCA series products form highly transparent films in a wide mixing range (0.05–20%) with many binder resins, including styrene-acrylic, polyester, epoxy, and hybrid types. |
| Charge stability | FCA series products have stable characteristics, and the charge amount can be controlled by adjusting the quantity added. |
| Safety | FCA series products offer excellent safety as they use high molecular weight polymers and contain no heavy metals. |
| Environmental compatibility | FCA series products offer high environmental compatibility due to their insolubility in water and high molecular weight. |
| Chemical registration | Act on the Regulation of Manufacture and Evaluation of Chemical Substances, TSCA, and others |

Block Polymers
We have developed a range of block polymer products with our unique technologies.
By incorporating both hard and soft resin segments into a single polymer, we are able to separate their functions, enhancing the properties of the resulting polymer to levels previously unattainable with random polymerization. Block polymers can be considered for a wide variety of applications, including pressure-sensitive adhesives, substrates, and dispersants.
