Electronics and New Energy Industry

Electronic pastes are generally composed of functional powders and organic carriers. Functional powders are the functional components of electronic slurries. In conductive slurries, they are generally powders of good conductive metals such as silver powder and copper powder, while in dielectric slurries, they are generally inorganic glass powder. For example, in rear projection applications, it can be inorganic powders with certain optical functions such as suppressing light scattering, as well as powders with colorant functions such as inorganic fillers. Organic carriers are auxiliary components in the slurry, mainly composed of resin adhesives and solvents.

In the production process of lithium-ion batteries, in order to control interface performance and provide a perfect collector coating, the good dispersion of particles is crucial for battery performance. WEK Chemical supplies additives in this market mainly for the production of electrode slurries and ceramic diaphragm coatings. WEK Chemical's wetting dispersant can more conveniently achieve uniform dispersion of various materials, such as conductive carbon materials such as carbon black and carbon nanotubes (CNTs). This helps to prepare a more uniform electrode slurry, which can improve the manufacturing process of anode and cathode plates. The application of WEK chemical wetting dispersants can significantly reduce the viscosity of slurries based on lithium iron phosphate (LFP), lithium nickel manganese cobalt (NCM), lithium nickel cobalt aluminum (NCA), or various other active cathode materials. In addition, WEK Chemical's wetting dispersant is also suitable for the dispersion of ceramic materials such as alumina and boehmite in diaphragm coatings. Surface aids optimize the wetting of the substrate and the leveling of the coating by reducing surface tension, ensuring a fast and defect free coating process on the substrate. In addition, the WEK chemical additive product series also includes customized defoamers, rheological additives that regulate the rheological behavior of the slurry, and adhesives with high adhesive strength, strong mechanical stability, and good heat resistance.
