SIGMA THERM FF-101 : Additive ideal De-Carbonizing chemical for use with heat transfer oils and fluids, particularly when they are thermally or oxidatively degraded. Its amazing powerful action provides a dramatic reduction in the viscosity of fresh and used heat transfer media while solubilizing any hydrocarbon oligomeric sludges and deposits in the heat transfer systems. SIGMA THERM FF-101 : Additives does not form any viscous or solid deposits that lead to fouling on heat exchanger surfaces or clogging of the heat transfer circuit. It is used to correct these types of problems.
