The inhibitor system is a high phosphate formulation and is compatible with all common metals in heat transfer fluid systems and is compatible with most plastic construction materials.

The recommended operating temperature range of ig-loo PGFG is -45ºF (-50°C) to +250ºF (120°C). The lowest temperature to which the finished product can be exposed depends upon the amount of water with which the concentration of product mixed.

ig-loo PGFG can be used to provide both freezing protection and burst protection for systems which may be exposed to very low temperatures.  ig-loo PGFG may be formulated to any concentration, with deionized water.
