XR-WBA-004 Grade A · Industrial Platform Polymer & Functional Resins

Weak-Base Anion Resin

Macroporous weak-base resin that protects strong-base beds from organic fouling.

Macroporous free-amine weak-base anion resin with high capacity and easy regeneration, used mainly as a guard bed to remove strong-acid anions and some organics, reducing organic fouling and regeneration load on downstream strong-base anion resin.
