Kelco-Crete DG-F
Kelco-Crete DG-F
Kelco-Crete® DG-F diutan gum is a water-soluble biopolymer produced by fermentation and supplied as a fine powder. It hydrates in with mix water and acts as a viscosity-enhancing agent (with pseudoplastic/shear thinning rheology profile) to prevent bleeding and segregation.
This product is suitable for stabilization of very fluid cement and calcium sulphate-based mixtures, e.g.:
- Cementitious or gypsum-based self-leveling underlayments (SLUs)
- Cementitious or gypsum-based flowing floor screeds
- Cementitious self-leveling decorative overlayments (SLOs)
- Cementitious self-leveling industrial floors
- Non-shrink grouts (machinery grouts)
- Injection mortars and most tension grouts
- Refractory materials
