Product Description

Mobilarma Double Letter Series are a range of high performance rust preventives.   The Mobilarma Series combines excellent corrosion protection and environmental awareness for a wide variety of applications, components and conditions.  

Mobilarma MT and Mobilarma LT are based on a carefully selected high flash point solvents and modern, technically advanced corrosion inhibitors.  The high flash point solvent has the affect of increasing coverage capacity meaning lower oil consumption.   Mobilarma MT and LT are free from added barium.  Mobilarma SF is a mineral oil based rust preventive, normally used for the protection of sheet steel.

Features and Benefits

FeaturesAdvantages and Potential Benefits
High flash point narrow cut solventsLower evaporation means lower oil consumption and improved operator acceptability
Effective dewatering and corrosion protectionRemoves all traces of moisture from components to lead to long-term rust and corrosion protection
Improved coverage capacityEnhanced product utilisation and lower product consumption
Multi purpose in applicationReduced inventory required.  Can be used on a variety of different feed stocks using a range of application methods
Thin, transparent robust filmsMakes it easier to read markings on components


Mobilarma MT is for a multi purpose rust preventative providing medium term protection of ferrous and alloy components during storage and transit.  It is particularly suitable for the protection of highly machined precision parts where heavy films are not desirable.

Mobilarma LT is for general purpose rust preventative providing medium to long term protection of ferrous and alloy components. It is especially suited for the protection, during storage, of many types of spares e.g. engine components, automotive parts as well as extruded and machined surfaces.  The protective film is very effective against acidic and other aggressive atmospheres.

Mobilarma MT and LT are best applied by dipping but they can be flooded, sprayed or brushed on.  Where necessary they can be removed by hydrocarbon solvents or suitable alkaline cleaners.

Mobilarma SF is a rust preventive for sheet steel, coil, wire and bar which improves lubricity and adhesion during reeling and straightening.  The oil can be used by dip, flood, spray or electrostatic blade coater.
