Printer-toner resin-type charge control agent (CCA, named FCA for Fujikura products)
The FCA series is the polymer charge control agents (CCR) developed by our company with our unique technology. They bring out excellent performance not only in charging characteristics but also in safety and transparency, different from the conventional CCR. They can be effectively used in electrophotographic materials, e.g., toner, carrier, and friction charging members as well as electrostatic painting. They have been widely used by many customers since being placed in the market in 1986.
- FCA-N ：Polymer charge control agent for negative charge
- FCA-P ：Polymer charge control agent for positive charge
|Dispersibility (compatibility)||They feature excellent compatibility and dispersibility (homogeneity) with binder resin because non-polar components and polar components bind together. They can be used for wide intended uses not only for the normal grinding system but also for polymerized toner (suspension method, latex method, and dispersion polymerization method), carrier coating materials, powder painting, and others.|
|Transparency||They form highly transparent films with many binder resins, e.g., acrylic-styrene, polyester, epoxy, hybrid type, and others in a wide mixing range (from 0.05 to 20%).|
|Charging stability||The charge amount can be controlled by the additive amount resulting in stabilized characteristics.|
|Safety||They are superior in safety because they do not include heavy metals, and they are polymers with high molecular weight.|
|Environmental adaptability||They are stable and have high environmental adaptability because they are not soluble in water, and have high molecular weight.|
|Register of Potentially Toxic Chemicals||Chemical Substances Control Law, TSCA, and others|
Organic fine particles can be obtained by our unique polymerization technique. A wide range of grades are assorted for the respective types of fine particles (acrylic, styrene, acrylic-styrene, crosslink, and porous microparticles). Adjustments of particle size (from 0.1 to hundreds of microns), degree of crosslink (solvent resistance), polarity, refractive index, composition, and others are available according to your order. They can be widely applicable to matting agents, light diffusing agents, anti-blocking agents, paint additives, and others.
We are able to respond to special order designs for various purposes with our technology that has been developed based on our accumulated know-how and performance.
