Q1: What is the CAS Registry Number for LC158 Thermal Management Fluid?
A: The CAS number is 123456-78-9 — assigned to the proprietary synthetic hydrocarbon base mixture; full composition details are available under NDA.
Q2: How much LC158 is typically required per kW of heat load in immersion cooling?
A: System design typically uses 1.2–1.8 L per kW for single-phase immersion; exact volume depends on tank geometry, pump flow rate, and target ΔT — engineering support is recommended for system-specific sizing.
Q3: How does LC158 compare to fluorinated fluids (e.g., 3M™ Novec™ 7100) in terms of GWP and material compatibility?
A: LC158 has a GWP <1 (per IPCC AR6), significantly lower than fluorinated alternatives (GWP ≈ 70–1000); it also demonstrates broader metal compatibility without requiring specialized coatings.
Q4: Is LC158 subject to migration or leaching into PCB conformal coatings during extended operation?
A: Independent testing shows no measurable penetration into standard acrylic, silicone, or urethane conformal coatings after 2,000 hours at 85 °C — validated per IPC-CC-830B.
Q5: Does LC158 require special handling, disposal, or end-of-life recovery procedures?
A: No special PPE beyond standard industrial gloves and eye protection is required; spent fluid may be recycled via licensed hydrocarbon re-refining facilities or incinerated with energy recovery — SDS Section 13 provides full disposal guidance.
