Macroporous Weakly Basic
Anion-exchange Specialty Catalyst


KP-3113 is a premium grade catalyst with a form of macroporous acrylic-based weakly alkaline anion-exchange resin, synthesized by special advanced technology. With its uniform and solid structure and low swelling rate of reversible replacement reactions, this resin performs excellent resistance to mechanical and osmotic shock as well as against organic pollution.

Attributed to its efficient properties of strong adsorption or large exchange capacity of weak-basic anions with strong-acid radicals of organic macromolecules including metal complexes within mineral liquids during its regeneration, KP-3113 model, as a role of catalyst, is primarily used in demineralization system and applied in sugar refining & wastewater treatment to prevent ‘strong-alkaline anions’ from being polluted by organics to the greatest extent, and induce and accelerate all the replacement reactions on top of all.
