Waterborne dispersants suitable for small particle size filler
Based on the interface control technology Kao has cultivated over many years in a wide range of fields from home use to industrial use, we have developed KAOCER series of applicable to a wide range of dispersoid. KAOCER series provides outstanding dispersion performance for ceramics, metals, silica, carbon black, and other materials throughout the electronic component manufacturing process. This contributes to the enhanced performance and reduced size of electronic devices.
What is KAOCER 2000 series?
KAOCER 2000 series is the waterborne anionic dispersants. They exhibit high dispersibility for a wide range of ceramics and metal particles. KAOCER 2000 series does not contain metallic ions such as sodium and potassium, and leaves no metal residue after combustion, making it applicable to electronic components.
Feature
Since KAOCER 2000 series is negatively charged, they exhibit high adsorption performance on positively charged ceramics and metal particles. In addition, the introduction of the insolubilization/adsorption unit in the molecule enhances adsorption to solid particles.
Dispersion mechanism
Since there is no adsorption unit in the molecule, the adsorption rate on the dispersoid (powder) is reduced.
The Insolubilization unit adsorbs strongly to the dispersoid (powder), resulting in the improved adsorption rate to the dispersoid.
The adsorption unit electrically adsorbs the dispersoid (powder), thus increasing the adsorption rate.
Solution
High dispersibility at optimum additive amount
KAOCER 2020
High dispersibility over a wide range of additive amounts
KAOCER 2110
Maintains dispersion for a long period of time
KAOCER 2110
High dispersibility is achieved at optimum additive amount, contributing to smaller particle size of fillers.

What is KAOCER MD-P?
KAOCER MD-P is the waterborne cationic dispersant. It exhibits high dispersibility, especially for silica and carbon black. This product does not contain metallic ions such as sodium and potassium, and leaves no metal residue after combustion, making it applicable to electronic components.
Feature
Since KAOCER MD-P is positively charged, it exhibits high adsorption performance on negatively charged solid particles.
Anionic dispersant
● No adsorption
● No viscosity reduction effect
KAOCER MD-P
● Static repulsion effect
● Demonstrates viscosity reducing effect
Solution
High adsorption performance on anionic solid particles. After adsorption, electrostatic repulsion is utilized to achieve a high dispersion effect.
