Product Description

SDP-750 (65% Active, 25% BDG, 10% Water) is a premium, specialized alkoxylate-based surfactant engineered for high-performance industrial fluid formulations. Featuring an optimal HLB value of 10, the core block polymer exhibits unparalleled capabilities as a co-emulsifier and chemical coupling agent, seamlessly bridging oil and water phases with exceptional stability. The factory pre-blended BDG-water vehicle effectively eliminates low-temperature gelation risks, maintaining excellent flowability and pumpability for rapid, energy-efficient room-temperature tank blending.

Key Applications & Technical Benefits

• Metalworking Fluids (MWFs) Optimization: Highly effective in semi-synthetic and fully synthetic cutting, grinding, and cooling fluids. It significantly promotes emulsion stability, prevents oil-water separation, and enhances overall fluid system longevity.

• Formulation Coupling & Solubilization: Demonstrates an outstanding ability to couple insoluble additives, extreme-pressure (EP) agents, and mineral oils into stable, crystal-clear water-based concentrates, preventing additive fallout during long-term storage.

• Lubricity & Film Strength Enhancement: Powered by the optimized active polymer chain (Mw ~750), it delivers a robust hydrodynamic lubrication film under boundary shear conditions, drastically reducing friction coefficient, heat buildup, and tool wear during high-speed machining.

• Controlled Foaming & Process Flowability: The unique structural synergy with the premium BDG solvent minimizes foam stabilization during high-pressure spraying and rapid pump circulation, ensuring seamless mechanical operations without the excessive need for tank defoamers.
