Weakly Acidic Cation Exchange Resins

WK10 grades (methacrylic type) are weak acid cation exchange resins having carboxylic acid functionalities. They have a pK value of approximately 6. WK10 has high reaction rate, and WK11 has a high totally exchange capacity. These methacrylic grades are mainly used for special applications such as purification of pharmaceuticals, foods, and organic chemicals.

WK100 and WT01S have high reaction rate and high adsorption capacity. They are mainly used for the purification of pharmaceuticals and foods. WT01S is offered in 100-300 µm particle distribution designed for high performance processing.

WK40L and WK60L are weak acid cation exchange resins with carboxylic acid functionality based on porous acrylic polymer matrix. They have a pK value of approximately 5.3. The acrylic type resins have higher total capacity than methacrylic type resins. They are mainly used for water treatment applications such as the removal of hardness ions in the presence of bicarbonate alkalinity.
