Product overview
Welan Gum is a microbial polysaccharide used mainly as a high-performance rheology modifier in cementitious materials, oilfield fluids, coatings and other systems requiring heat and salt tolerance. It is positioned primarily as an industrial additive; any food use must be supported by the exact grade documentation and explicit destination-market authorization.
Function & Usage
- Thicken, Gel & Stabilize
Provides stable rheology and suspension, including in high-temperature or high-salinity process systems. Typical uses: Cement and concrete rheology, Oilfield and high-salinity fluids, Coating and pigment suspension.
- Control Rheology & Water Retention
Controls viscosity, suspension, sag resistance or water retention in suitable coating and construction formulations. Typical uses: Cement and concrete rheology, Oilfield and high-salinity fluids, Coating and pigment suspension.
- Improve Mortar Workability & Set Control
Supports workability, water management, set profile, adhesion or durability in cementitious and dry-mix systems. Typical uses: Cement and concrete rheology, Oilfield and high-salinity fluids, Coating and pigment suspension.
- Build Drilling-Fluid Rheology
Supports viscosity, suspension or carrying performance in compatible drilling-fluid and oilfield systems. Typical uses: Cement and concrete rheology, Oilfield and high-salinity fluids, Coating and pigment suspension.
