8516
Coating Binder for Ceramics
Binder-8516 is a polyacrylate-based emulsion featuring core-shell particle structure, with blends of monomers with high/medium/low glass transition temperatures (Tg), making it suitable for binding purpose on lithium-ion batteries separators, and other various powdered materials such as ceramics and resins.
Product Overview:
Key Features:
Core–shell structure design provides enhanced adhesion performance in humid environment
Low surface tension ensures excellent wettability on base films, resulting in strong adhesion and low water uptake
Low electrolyte swelling with good electrolyte affinity, enabling high ionic conductivity of the coated membrane
Strong resistance to oxidation and reduction, delivering stable electrochemical performance
