BATTBOND 3930 is a multi-polymer of acrylic acid and its derivatives, and the polymer has stable electrochemical properties. The main chain is mainly C-C bonds. Strongly polar side groups such as -CN have excellent bonding properties and good wettability to electrolytes; acrylic acid and acrylic acid derivative segments give the adhesive molecules flexibility and better ion conduction properties. Ultra-high molecular weight, excellent bonding performance to current collectors; good solubility in NMP.
