Properties / Benefits
GOODGEL MAS AQUEOUS GRADEprovides the following benefits:
Controlbleeding. Suspensions that tend to settle are easily redispersed.
Ensureproducts of uniform dosage: pharmaceutical suspensions and pesticide concentrates,among others.
Achievemaximum suspension without losing pourability.
Donot form gelatinous, irreversible gels, as do many organic gums.
Offerbetter suspension efficiency than do organic gums at equal viscosity; they areespecially useful at low viscosities.
Dosage and Handling
GOODGEL MAS AQUEOUS GRADE can be added to other powdery components and mix to get a homogenousformulation. It can be also made preparation of gelation dispersions beforeuse.
The dosage may vary from 0.2%-4% of the totalmaterial by weight. The actual required dosage should be evaluated in suitabletests prior to final application.
