Product Description

SDP-600 (65% Active, 25% BDG, 10% Water) is a high-performance specialty alkoxylate solution tailored for heavy-duty industrial fluid applications. Characterized by a low HLB value of 5, the core block polymer is engineered to exhibit superb solubility and high-affinity blending in mineral oils, PAOs, and synthetic hydrocarbon bases, making it an essential functional building block for advanced fluid formulations. The factory pre-blended BDG-water vehicle effectively suppresses the high inherent viscosity of the active polymer, rendering it highly pumpable and instantly dispersible without the need for auxiliary heating.

Key Applications & Technical Benefits

• Metalworking Fluids (MWFs) Lubricant Base: Functions as an outstanding oil-soluble lubricating agent and boundary co-emulsifier. It is highly optimized for soluble cutting oils, semi-synthetic, and full-synthetic metalworking fluid concentrates.

• Advanced Industrial Lubricant Blending: Serves as a premium functional additive component and synthetic base stock modifier for high-temperature industrial lubricants, gear oils, and specialized hydraulic fluids.

• Superior Extreme-Pressure (EP) Film Strength: The structured polyether polymer chain delivers exceptional boundary lubrication. Under severe load conditions, it deposits a robust polymeric film on metal surfaces, significantly reducing friction coefficient, tooling heat, and workpiece micro-wear.

• Optimized Handling & Cold-Weather Flow: Unlike pure polymers that suffer from high winter pour points, the pre-diluted SDP-600 system eliminates low-temperature gelation risks. It ensures rapid room-temperature tank blending, reduces process handling energy costs, and contributes to system-wide micro-defoaming properties during high-speed machining operations.
