T50B Carbon Nanotube Dispersion in UV-curable Resin

T50B is a concentrated dispersion of discrete, dispersed, and functionalized carbon nanotubes (D’Func) in UV-curable resins. A more versatile dispersion than E35A, this material can be used in SLA, DLP, or jettable resins ranging from rigid to flexible to provide conductivity and decreased surface resistivity. When compared to FDM-printed ESD parts, ESD resins produced with T50B can achieve fully isotropic conductivity with high resolution and isotropic mechanical properties.
