Solubility & Compatibility Considerations
- Soluble in water and selected organic solvents
- Soluble in acetone, alcohol, chloroform, toluene, and dichloromethane
- Hydration and final viscosity depend on concentration, mixing method, temperature, shear, and rest time
- Compatibility should be evaluated with salts, additives, pigments, fillers, solvents, and other formulation components before scale-up
- Formulation performance depends on molecular weight, polymer concentration, processing conditions, and intended end use
Final performance should be confirmed under the user’s specific formulation and processing conditions, including polymer concentration, solvent system, mixing order, temperature, and application requirements.
Preparation Tips
- Add gradually to the liquid phase with adequate mixing to reduce clumping
- Allow sufficient time for full hydration and viscosity development
- Avoid excessive dust generation during powder transfer
- Use clean equipment to reduce contamination during solution preparation
- Run small-scale compatibility and viscosity trials before production or process transfer
Handling & Storage
- Store at room temperature
- Exercise normal care during handling
- Keep container tightly closed when not in use
- Use good ventilation and standard laboratory or industrial safety practices
- Avoid unnecessary dust generation during powder handling
- Wear protective gloves and safety glasses when appropriate
- Refer to the Safety Data Sheet before handling
