Kraft lignin is a natural, renewable product derived from wood. REAX 88A is the sodium salt of a chemically modified low molecular weight kraft lignin polymer. It is recommended as a primary dispersant for water-based and dry formulations of organometallic and alkali-sensitive active ingredients.

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 81A is the sodium salt of sulfonated modified kraft lignin. It is used in a broad range of dye applications where grinding efficiency and good heat stability are required. It is also used in dry and water-based agricultural formulations.

REAX 85A is the sodium salt of a chemically modified medium molecular weight kraft lignin polymer. It is a primary dispersant in disperse dye formulations where heat and storage stability are required.
