Features and Benefits

Mobilarma 777 and 778 provide an effective and cost efficient means of protecting cold-rolled sheet and coiled steel prior to processing and during storage. They provide extended protection, even under severe storage conditions resulting in less reject and scrapped materials.

Mobilarma 798 works well between the strands of wire rope providing excellent lubrication as well as protective films. These characteristics reduce wear and improve life of the wire ropes as well as minimize maintenance costs associated with their use. It is compatible with other wire rope core impregnating materials that may have been applied during manufacture. It is easy to apply and economical to use.
Advantages and Potential Benefits
