Acrylic Ceramic Binder (PAA)
CAS Number: 9003-01-4
Polyacrylic acid (PAA) and its ammonium or sodium salt copolymers are used as binders and dispersants in aqueous ceramic tape casting, screen printing pastes, and multilayer ceramic capacitor (MLCC) slurries. These acrylic binders deliver strong green films with controlled flexibility, and decompose cleanly at low sintering temperatures.
