Harmonization Code : 3403.19 | Lubricating Preparations (With 70% or More Petroleum Oils) For Automotive and Other Uses
Main features
- 4,800 N Four-Ball Weld Load
- 0.10 Press-Fit Friction Coefficient
- -25 to 125 deg C Service Range
Product Description
MOLYKOTE® DX (S) Paste is a white to off-white, mineral-oil-based grease-paste with lithium soap, white solid lubricants, and a corrosion inhibitor for assembly and long-term lubrication of heavily loaded metallic contacts. It is intended primarily for clean lubrication at low to medium speeds and has a documented service range of -25°C to 125°C. Typical test data include a 4,800 N four-ball weld load, a 0.77 mm wear scar under 800 N for 1 hour, a 0.10 press-fit coefficient of friction with no chatter, and a 0.12 SRV fretting coefficient under the stated test conditions. Apply to clean contact points by brush, spatula, grease gun, automatic device, or central lubrication system.
Key features
- Clean, light-colored lubrication: White to off-white grease-paste for metallic sliding contacts where visible dark lubricant residue is undesirable.
- Heavy-load test performance: DIN 51350 four-ball weld load of 4,800 N and Almen-Wieland OK load of 20,000 N.
- Friction and fretting data: Press-fit coefficient of friction of 0.10 with no chatter and ASTM D7594 SRV fretting coefficient of 0.12.
- Water and corrosion test results: DIN 51807 static water-resistance rating of 0-90 and DIN 51802 SKF-Emcor corrosion rating of 2 or lower.
- Flexible application: Suitable for brush, spatula, grease-gun, automatic-device, and central-system delivery.
- Fluorinated-material statement: Formulated with no intentional PTFE or other PFAS.
Applications / Suitable for
- Slides, guides, tracks, and other heavily loaded sliding surfaces
- Plain bearings, bushings, sleeves, and power screw drives
- Electrical and domestic appliance mechanisms
- Packaging, office, and precision machinery
- Textile and plastics-processing machinery

Additional Information
MOLYKOTE® DX (S) Paste
A light-colored mineral-oil grease-paste with lithium soap, white solid lubricants, and a corrosion inhibitor. It is designed for assembly and long-term lubrication of metallic sliding contacts exposed to heavy loads at low to medium speeds, especially where clean appearance, controlled friction, and resistance to stick-slip or galling are important selection factors.
MOLYKOTE® DX (S) Paste is a white to off-white grease-paste for clean lubrication of heavily loaded metallic contacts.

Apply to clean metallic contact points
Use conventional grease-paste application methods selected for the component geometry and maintenance process. The paste may be applied manually, by automatic lubricating equipment, or through a central lubrication system.
Store between 0°C and 40°C in the original unopened container. Usable life is 60 months from the date of production. Review the current safety data and container label before handling, use adequate ventilation, and avoid contact with strong oxidizing agents.
Clean, heavy-load lubrication applications
The documented application scope centers on metallic sliding and friction contacts exposed to heavy loads at low to medium speeds. The light-colored paste is particularly relevant where clean appearance and controlled sliding behavior matter alongside load, water-resistance, and corrosion-test performance.
