Description
Castrol Molub-Alloy 936 SF Arctic is a uniquely compounded open gear lubricant specifically formulated for extreme cold
operating conditions and for use on heavy duty equipment in mining and industrial service. Molub-Alloy 936 SF Arctic is
compounded to give maximum protection to gears and slides on large draglines and shovels while minimizing potential
pollutants to the environment.
Molub-Alloy 936 SF Arctic is part of Castrol Performance Lubricants’ Eco-Solutions™ product offering. Formulated to
address environmental concerns, Molub-Alloy 936 SF Arctic is free of lead, antimony, barium, and chlorinated solvents.
No solvents of any kind are used in 936 SF Arctic.
A highly refined, viscous, paraffinic petroleum derivative is the foundation of a blended base fluid with excellent natural
chemical and thermal stability.
A proprietary blend of Castrol Molub-Alloy lubricating solids is included to promote antiwear and load carrying properties
beyond those of conventional lubricants. The select lubricating solids work synergistically with chemical antiwear and
extreme pressure (EP) additives to reduce contact temperatures while providing excellent antiweld protection under
extreme pressure and shock loading.
Rust and oxidation inhibitors are included in the formulation to protect the equipment and the lubricating film against the
elements in severe climate.
Application
Mining applications include all types of open gears, rails and rollers, racks and pinions, dipper sticks and other slides on
shovels and draglines. Molub-Alloy 936 SF Arctic may be applied either manually or by heavy duty automatic systems.
936 SF Arctic should pump and spray readily down to -30°F/-35°C and possibly lower depending on the nature of the
hardware (see Typical Properties.)
