Modified Epoxy Cardanol IPN Protective System for Concrete & Steel Structures

Applications

Corrosion Protection

Salient Features

The system is based on the synthesis of epoxy cardanol under vacuum. Cardanol is a phenol obtained from fractional distillation of CNSL resin. The condensation of epoxy resin with cardanol is carried out in a reaction kettle at elevated temperature under inert atmosphere. The output is checked for alkalinity and then discharged from the vessel and collected at room temperature.
