Molybdenum Dithiocarbamate (MoDTC)
CAS Number: 68412-36-2
Molybdenum dithiocarbamate (MoDTC) is an oil-soluble organo-molybdenum compound widely used as a friction modifier in engine and drivetrain lubricants. It decomposes under tribological stress to generate in-situ MoS2 nanoparticles that reduce boundary friction coefficient by 30–50%, improving fuel economy. MoDTC is a key component of fuel-efficient engine oil formulations meeting ILSAC GF-5/GF-6 and ACEA C2/C3 specifications.

Applications
- Fuel-efficient passenger car motor oils meeting ILSAC GF-5/GF-6 standards
- Low-viscosity engine oils (0W-20, 0W-16) for Japanese and European OEMs
- Continuously variable transmission (CVT) fluids
- Hybrid vehicle transmission and engine fluids
- Industrial gear and hydraulic oils requiring friction reduction
Key Features
- Reduces boundary friction coefficient by 30–50% for measurable fuel economy improvement
- In-situ MoS2 formation provides durable low-friction tribofilm without mechanical deposition
- Synergistic performance with ZDDP and amine antioxidants in engine oil packages
- Good thermal stability up to 200°C ensuring performance through extended drain intervals
