Rheology Modifiers
FEATURES
General Properties: Exhibit non-Newtonian, shear-thinning (pseudoplastic) behavior; they provide high viscosity at rest (low shear) and low viscosity when pumped or agitated (high shear).
Synergistic Role in Defoamers: They build a "suspension matrix" that physically locks defoamer droplets and hydrophobic silica particles in place during storage, preventing them from migrating, creaming, or settling due to gravity.
Performance Benefits:
Provides Yield Stress: Effectively suspends heavy or large defoamer components that would otherwise separate.
Prevents Phase Separation: Significantly enhances shelf-life by preventing creaming (oil rising) or sedimentation (solids sinking).
Excellent Pumpability: Because they are shear-thinning, the defoamer flows easily through pipes and dosing pumps when force is applied, despite being highly structured at rest.
