ResinTech MBD-100 is a 2:3 volumetric mixture of CG8-H-ID (a dyed hydrogen form cation resin) and WBMP (a free base form macroporous weak base anion resin). The cation component is dyed royal purple and changes color as it exhausts. MBD-100 is intended for cartridge and other single-use applications where carbon dioxide and silica removal is not required, where high resistivity is not needed, and where a color indication of resin exhaustion is desired.

  • Cartridge Applications (Reduction of CO₂ and SiO₂ is not required)

  • Bulk Ion Reduction
