Diutan gum DG-P is a fine mesh, rapid hydrating, water soluble biopolymer produced
ØImparts high solution viscosity at low gum concentrations
ØHas pseudoplastic rheology profile (e.g., is shear thinning) providing:
llow viscosity at high shear rates ( Easy to pump & place )
lhigh viscosity at low shear rates ( Provides superb particle suspension)
ØExhibits little solution viscosity change over a wide temperature range.
ØProvides excellent suspension and emulsion stability at lower viscosities.
ØImproved pumping, placement and workability.
ØIs stable under high-shear.
ØExhibits low viscosity while processing (e.g., pumping and spraying).
ØProvides excellent water retention.
ØImproves shelf life stability of high pH products.
ØHomogeneous placement and curing of aggregate, sand, pigment and past.
lImproved surface properties and durability
lImproves pigment efficiency and provides consistent color quality
ØBleed control improves quality, and may reduce labor finishing costs.
ØReduces impact of raw material variability on costs and quality.
lReduces impact of moisture in sand and aggregate
lReduces impact of gap graded sand and aggregate
ØStabilizes highly fluid mix designs for Gypsum Systems, Self Compacting
Concrete and Underwater Concrete Systems.
ØGypsum floor screeds
ØSelf Compacting Concrete (SCC)
ØInjection & post tension grouts
ØPigmented concrete & gypsum systems
ØSelf Leveling Underlayments (SLU)
ØUnderwater concrete (anti-washout)
Biopolymer DG-P is typically used at a level of 0.01 - 0.15 wt% basis weight of water.
