1. Product Introduction & Main Application
Arnico’s Base Oil SN 150 is a mid-viscosity, general-purpose Group I mineral base oil, obtained from the solvent refining process of lube oil cuts. This substance, the world’s most consumed grade of base oil, is the primary foundation for the production of a wide range of automotive and industrial lubricants, including conventional engine oils, gear oils, standard hydraulic fluids, and various types of greases.

Metalworking Fluids: The base for soluble cutting emulsions and neat lubricants.
-
Grease Manufacturing: The base fluid for medium-grade lithium and calcium greases.
5. Safety & Handling
-
MSDS (Material Safety Data Sheet): Prolonged skin contact may cause dryness. It is flammable at high temperatures. The Arnico MSDS file must be obtained.
-
Storage Conditions: Store in sealed carbon steel tanks, away from moisture, water, and suspended particles, at ambient temperature.
-
Personal Protective Equipment (PPE): Oil-resistant gloves and safety goggles are recommended.
6. Quality Assurance & COA
All Arnico SN 150 shipments are accompanied by a Certificate of Analysis (COA) detailing the viscosity, viscosity index, and flash point.
