N-904 is a high-molecular-weight, 100% active, solvent-free tetrafunctional star-shaped block copolymer surfactant. Engineered with an elite ultra-hydrophilic HLB value of 39.5 and an elevated cloud point of 70°C, it is explicitly designed to provide superior emulsification, solubilization, and dispersing capabilities in highly demanding polar aqueous environments. Its four-arm continuous cross-linked structure ensures unparalleled thermal and mechanical shear stability.
Advanced Solubilization & Emulsification: Outstanding capability for solubilizing complex organic components, performance additives, and specialty synthetic oils into water-rich systems without compromising formulation clarity.
High-Shear Lubricant Performance: Ideal for premium semi-synthetic and fully synthetic metalworking fluids, maintaining its continuous hydrodynamic film-lubricity barrier and molecular integrity under intense mechanical loads.
Elite Dispersing Efficiency: Provides exceptional wetting and steric stabilizing performance for dispersing fine inorganic powders, fillers, and advanced pigments within water-borne coatings, inks, and specialized aqueous industrial concentrates, preventing hard settling over extended shelf lives.
Sustained Thermal Stability: The stable 70°C cloud point ensures consistent, predictable surface-active performance in heated mechanical operations or warm operating environments.
