Properties / Benefits
GOODGEL MAS AQUEOUS GRADE provides the following benefits:

• Prevent hard packing of the suspended material.
• Control bleeding. Suspensions that tend to settle are easily redispersed.
• Ensure products of uniform dosage: pharmaceutical suspensions and pesticide concentrates, among others.
• Achieve maximum suspension without losing pourability.
• Do not form gelatinous, irreversible gels, as do many organic gums.
• Offer better suspension efficiency than do organic gums at equal viscosity; they are especially useful at low viscosities.

Application
GOODGEL MAS AQUEOUS GRADE may be used in a variety of aqueous system applications, and you may find suggested applications from Physical Specification tables in this file.

Dosage and Handling
GOODGEL MAS AQUEOUS GRADE is added to other powdery components and mix to get a homogenous formulation. It can be also made preparation of dispersions before use.
The dosage may vary from 0.2%*4% of the total material by weight. The actual required dosage should be evaluated in suitable tests prior to final application.

Preparation of dispersions: add 3~5% GOODGEL MAS AQUEOUS GRADE into water, agitate for *0~*0mins with high speed till to homogeneous dispersion acquired.

Storage
GOODGEL MAS AQUEOUS GRADE may be stored in sealed bags under dry cool place for at least *2 month. Opened packages should be sealed again as soon as possible. Not exposure to water, sunlight, especially during transportation.

Package
*5kg/bag: multiply paper or plastic woven bag with polyethylene interlayer
