D301 is a very high capacity, bead form, weak base, macroporous type, anion resin. D301 is a very high capacity, bead form, weak base, macroporous type, anion resin made by epoxy polyamine condensation. It is a spherical bead form resin(unlike other granular formulations) suitable for use in high flowrate applications. The exceptionally high operating capacity and regeneration efficiency of D301 ...
