HEUR (Hydrophobically Ethoxylated URethane)
HEUR (Hydrophobically Ethoxylated Urethane) rheology modifiers are non-ionic, associative polyurethane-based additives designed to control viscosity and flow in coating formulations.
Their mechanism relies on hydrophobic associations between polymer chains and formulation components, enabling efficient rheological control without requiring pH adjustment.
Key benefits & main applications:
Key benefits of HEUR rheology modifiers include improved flow control, enhanced leveling, strong sag resistance and consistent handling properties during application.
Their associative behavior enables shear-thinning under application conditions while maintaining sufficient structure at rest, resulting in reliable performance and formulation consistency.
Main applications include architectural and industrial coatings, inks, adhesives and sealants, as well as selected home care and specialty formulations requiring stable and predictable rheological behavior.
