Product Details
Technical Spotlight: Dialkyl Dithiocarbamate
Multifunctional Ashless EP / Anti-Wear / Antioxidant
Chemical Identity: 4,4'-Methylene bis(dibutyldithiocarbamate)
CAS Number: 10254-57-6
Product Overview
Dialkyl dithiocarbamate is a high-performance, sulfur-and-nitrogen-based organic additive designed for the most demanding lubrication environments. Unlike traditional metallic additives, this ashless component offers a unique "Triple Action" performance profile: it functions simultaneously as an Extreme Pressure (EP) agent, a long-life Antioxidant, and a robust Anti-wear (AW) additive.
At Chemost, we supply this component specifically for blenders seeking to eliminate ash-forming metallic salts without sacrificing load-carrying capacity or oxidation stability.
Primary Performance Features
- Multifunctional Efficiency: Reduces the total number of additives required in a formulation by providing three critical functions in one molecule.
- Ashless Protection: Ideal for environmentally sensitive applications or systems where metallic deposits/sludge must be avoided.
- Superior EP Performance: Specifically engineered to provide high Timken and Four-Ball weld load results in both lubricating oils and heavy-duty greases.
- Oxidation Inhibition: Effectively scavenges free radicals and decomposes peroxides, significantly extending the service life of the base fluid.

Industrial Application Guide
1. High-Performance Lubricating Greases
Dialkyl dithiocarbamate is a staple in the production of Lithium Complex, Polyurea, and Calcium Sulfonate greases.
- Use Case: Enhancing the load-carrying capacity of wheel bearing greases or industrial machinery grease.
- Impact: Increases weld point and reduces wear scars in high-load, low-speed oscillation environments.
2. Industrial and Automotive Gear Oils
For API GL-5 and heavy-duty industrial gear oils (ISO VG grades).
- Use Case: Provides ashless EP protection to protect gear teeth under shock loading.
3. Hydraulic and Turbine Fluids
- Use Case: Acting as a secondary antioxidant and anti-wear agent where low ash content is a regulatory or technical requirement.
Treat Rate Recommendations
- Lubricating Oils: 0.2% — 1.0%
- Lubricating Greases: 1.0% — 5.0%
Compatibility & Synergistic Performance
Our 4,4'-methylene bis(dibutyldithiocarbamate) demonstrates high chemical stability when blended with other Chemost components:
- With ZDDP: Shows excellent synergy in anti-wear performance, often allowing for a reduction in total zinc content while maintaining wear protection.
- With Phenolic Antioxidants: Works together to provide enhanced high-temperature oxidation resistance.
- Base Oil Versatility: Fully compatible with API Group I-IV base stocks.
B2B Supply & Global Documentation
Chemost is committed to being a transparent and reliable partner for lubricant manufacturers and wholesalers. We ensure that every shipment is backed by a professional documentation suite:
- Technical Data Sheet (TDS): Complete physical and chemical property profiles.
- Material Safety Data Sheet (MSDS): Integrated safety and handling instructions in compliance with GHS standards.
- Certificate of Analysis (COA): Verifying that every batch meets the strict quality thresholds required by your production plant.
Frequently Asked Questions (FAQ)
Q: Can this product replace ZDDP entirely?
A: In many ashless formulations, it can serve as a primary anti-wear/EP agent. However, for internal combustion engine oils, it is often used alongside ZDDP to enhance oxidation control and high-load protection.
Q: Is the sulfur in this product "active" or "inactive"?
A: This is a thermally stable, relatively inactive sulfur source at low temperatures, making it safe for use in systems containing yellow metals (copper/brass) when used at recommended treat rates.
Q: Does it affect the color of the finished lubricant?
A: At typical treat rates, it adds a slight amber tint but maintains excellent clarity and does not cause cloudiness in the oil.
