Description

Cold Ramming Paste GSLD-1 has been developed for using in aluminium electrolysis cells.It has a very low concentration of benzo[a]pyrene equivalent compounds,
and the exposure during installation is very limited in the recommended temperature range of application. This paste shows favourable values for thermal shrinkage during baking.

Cold Ramming Paste GSLD-1 is easy to install and can be used in the temperature range 17 – 42 °C.
The ramming can be precisely controlled by use of a penetrometer and calibration curves.Both the penetrometer and calibration curves can be supplied by our company.

The paste should be stored under roof and not exposed to direct sunlight. It is important that the complete packing is kept intact. As a guideline, the shelf life is 12 months
from the date of production when stored below 25 °C.Under extreme storage conditions the shelf life may be considerably shorter.
