Experts recommend using hyperdispersants in electronic slurries, mainly based on the following significant advantages of hyperdispersants:
1. Efficient dispersion performanceRapidly wet particles: Hyperdispersants can quickly and fully wet particles, effectively shortening the grinding time to reach qualified particle fineness.Increase solid particle content: Hyperdispersants can greatly increase the solid particle content in the grinding base, thereby saving processing equipment and processing energy consumption, improving production efficiency and reducing production costs.2. Good stabilityUniform dispersion: Hyperdispersants can make particles dispersed evenly in the slurry and maintain the stability of the dispersion system.Long-term stability: Hyperdispersants will not introduce oleophilic films on the surface of particles, so they will not affect the application performance of the final product, and can maintain the stability of the dispersion system for a long time.3. Wide applicabilityApplicable to a variety of particles and dispersion systems: Hyperdispersants are suitable for a variety of different types of particles and dispersion systems, including aqueous and non-aqueous systems.Adjustability: Hyperdispersants can adjust the polarity and solubility parameters of the solvation chain by changing the feed ratio of the comonomer, thereby adapting to different dispersion requirements.4. Excellent adsorption performanceMulti-point anchoring: Hyperdispersants form multi-point anchoring on the surface of particles, which improves the adsorption fastness and is not easy to desorb.Forming a protective layer: Hyperdispersants can be tightly adsorbed on the surface of particles to form a stable protective layer to prevent the agglomeration and sedimentation of particles.5. Environmental protection and safetyEnvironmentally friendly hyperdispersants: With the improvement of environmental awareness, more and more environmentally friendly hyperdispersants have been developed, and the impact on the environment is getting smaller and smaller.Non-toxic and harmless: Hyperdispersants themselves are non-toxic and harmless, and have little impact on the health of operators.6. Improve product qualityImprove dispersibility and stability: The use of hyperdispersants can significantly improve the dispersibility and stability of products, thereby improving the quality and performance of products.Optimize application performance: In electronic pastes, hyperdispersants can ensure uniform dispersion of solid particles in organic carriers, prevent particle agglomeration, and improve the conductivity, adhesion and printing performance of the paste.
