GLOBE FGC MORTAR is a specially formulated Furan based Graphite mortar for chemicals resistant bricks construction. Especially for carbon Bricks Lining in Phosphoric Acid plant, Fertilizers & chemical Industries.
Field of Application
GLOBE FGC MORTAR is recommended for Brick lining in Tanks, Floors, Vessels, Sumps and Trenches requiring the chemical, physical or thermal resistance of brick construction.
With its broad range of chemicals resistance and temperature resistance (180C), GLOBE FGC MORTAR is ideal for the chemical processing and metal treatment industries, Phosphoric & HF Plants, Fertilisers, Food, & Pharmaceuticals Industries.
Chemical Resistance
GLOBE FGC MORTAR is resistant to organic acid, solvent, oils, greases and salts. It is also resistant to many inorganic acids and alkalis. GLOBE FGC MORTAR complies with the specifications of ASTM for chemicals resistant furan resin mortars.
Properties
High chemicals resistance, particularly to acids, alkalies and certain solvents.
High temperature resistance up to 1800C.
Lower shrinkage in furan resins
Electrically conductive, wherever required.
Long shelf life even at higher temperature. Approx. 18 Months.
High Mechanical strength.
Available Colours
GLOBE FGC MORTAR is available in black colour only.

Mixing of the FCG
Mixing of the components should be with mixer with a 5 kg. mortar capacity. The mixing speed should be between 50-60 RPM.Stir the content of the resin container prior to blending. The amount of the poser may be carried slightly to obtain the desired consistency. Proportionally increase or decrease component as per batch size requirement. Mixing of material may be possible manually into the metal pot container as per required quantity to be used for lining purpose. A thick black gravy solution will be recommended for lining with ratio 2:1 (Powder to liquid)

Storage & Shelf Life
The resin & mortar should be kept in cool & dry place tightly closed, away from moisture, heat & direct sunlight. For safety reasons keep both resin & powder away from each other.
Both the materials have a shelf life of min. 18 months as recommended conditions.
In case the ambient Temp. is more than 30-35o C, the shelf life of above materials will get reduced accordingly.
Health & Safety
Adequate ventilation is to be provided while work is in progress. Ventilation is compulsory for all work carried out in pits and closed rooms. All vapours that are produced while work is in progress must be continuously suctioned off at floor or bottom level. Mostly the mixing of mortar is to be carried out at open surface. Only the amount of material effectively required to continue work is to be stored at working place. The instruction for the prevention of fire and explosion are to be observed, if required. Please note and ensure that, even the smallest quantities of the individual components and/or pre-prepared mixtures are not allowed to reach the sewerage. All regulation for the prevention of accidents prescribed at the site of application & surface treatment in rooms and tanks, as well as the safety precautions listed on the packing (label) required by the provisions of the Hazardous Materials ordinance shall be adhered.
