MechT E35A: CNT Masterbatch in BR-952
MechT E35A is a stable dispersion of discrete functionalized carbon nanotubes 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 MechT E35A can achieve fully isotropic conductivity with high resolution and isotropic mechanical properties.
