E35B+
E35B+: CNT Dispersion in BR-952
E35B+ is a stable dispersion of discrete, dispersed, and functionalized carbon nanotubes (D’Func) in urethane dimethacrylate (UDMA), BR-952. The Masterbatch can be used in rigid, high tensile strength SLA, DLP, or jettable resins to provide conductivity and decreased resistivity. When compared to FDM-printed ESD parts, ESD resins produced with E35B+ can achieve fully isotropic conductivity with high resolution and isotropic mechanical properties.
