Biopolymer DG-P is a rapidly dispersible high viscosity, rapid hydrating, water soluble biopolymer produced by fermentation for use in gypsum and hydraulic cementitious systems, as a viscosity modifying agent (VMA) specifically used where super pseud plasticity characteristics are required such as cementitious materials and oil and gas drilling.

Biopolymer DG-P was developed specifically for use with cementitious materials and the newest class of superplasticizers. It enables formulators and designers to improve the performance of hardened materials by controlling flow, segregation, sedimentation and bleed. In addition, DG-P develops a higher degree of pseud plasticity, greater low shear rate viscosity (LSRV), and improved viscosity retention at elevated temperatures when compared to traditional polymeric rheology modifiers used in drilling, workover or completion fluids.

Application and Advantages
DG-P Biopolymer is a fine mesh, rapid hydrating, water soluble biopolymer produced by fermentation for use in gypsum and hydraulic cementitious systems, as a Viscosity Modifying Agent (VMA).
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)
DG-P Biopolymer is typically used at a level of 0.01 - 0.15 wt% basis weight of water.
The dissolution of the product depends on the medium and the process: it is improved by heat-treatment (time, temperature), shear-stress (propeller, exchanger, homogenizer). A complete dissolution can be obtained in cold conditions.
Packaging & Storage
DG-P is packaged in 50lb or 55lb plastic lined 4-layer paper bags and shipped via an approved common carrier. DOT classification – Non Hazardous.
DG-P has a shelf life of 24 months from date of manufacture when stored in a clean dry area.
