REAX 83A is the sodium salt of sulfonated modified kraft lignin. REAX 83A is an effective milling aid when used in wet grinding processes. REAX 83A functions as an effective primary dispersant

REAX 910 is a medium-sulfonated kraft lignin dispersant featuring low free electrolyte content, low conductivity and near neutral pH. This combination of properties makes REAX 910 suitable in liquid dispersion systems where free electrolytes tend to promote gelation and agglomeration of the suspended material.

REAX LS is the sodium salt of a chemically modified, medium molecular weight kraft lignin polymer. It is a primary dispersant in disperse dye and agricultural chemical systems where a combination of excellent heat stability, storage stability and low fabric stain are required.

REAX 907 is the sodium salt of a low molecular weight, highly sulfonated kraft lignin polymer. It is used in specialized applications where specific properties such as high metal complexing capacity, acid solubility, or superior viscosity reduction are required.
