The coating  be applied in three layers , as follows :
Epoxy Resin Coat Thickness 60 µ  to  600 µ  By Electrostatic Spraying
Bonding Agent Coat Thickness 170 µ  to  250 µ  By Electrostatic Spraying
Polyethylene Coat 2.2 mm  to  3.5 mm  By Extruder Hosed Film
 
Coat thickness be dependent on pipe size , as follows :
