Mobilarma 798

Wire Rope Rust Protective and Lubricant

Product Description

Mobilarma 798 is a premium performance, oil-based rust preventive intended to serve as a wire rope lubricant and to prevent rust and corrosion under application and storage conditions. It is used in industrial, mining, and marine applications. Mobilarma 798 has excellent film forming properties and is of grease-like consistency. Its tenacious film protects wire ropes from the corrosive tendencies of salt spray and moisture-laden atmospheres.  Mobilarma 798 is effective throughout the extremes of temperatures that may be encountered at sea and gives good protection against mild acids. It is pliable at -35ºC and will not drip at 60ºC. It resists throw-off in high-speed service and adheres without being tacky or stringy. On application, Mobilarma 798 becomes transparent enabling treated ropes to be visually inspected. The film is self-healing and does not chip.

Mobilarma 798 works well between the strands of wire rope, providing excellent lubrication during flexing. This characteristic reduces wear and improves life. It is compatible with other wire rope core impregnating materials that may have been applied during manufacture.

Features and Benefits

Mobilarma 798 works well between the strands of wire rope, providing excellent lubrication during flexing. This characteristic reduces wear and helps improve life. It is compatible with other wire rope core impregnating materials that may have been applied during manufacture. Its excellent rust and corrosion protection properties substantially reduce the negative effects of fresh water, salt water and mild acids thus improving performance and reducing maintenance costs. It is easy to apply and economical to use.
