Application Area Lignin
Gypsum plasterboards

The addition of lignosulfonate to a plaster suspension for natural and REA plasters significantly liquefies the slurries.

This means that, given an equal ratio of water to solids, the viscosity of the slurry is significantly lower when the dispersant magnesium lignosulfonate is added. The slurry can therefore be more easily processed by the production equipment.


We recommend our COLLEX® products for dispersion of plaster suspensions.
