NextGen NP-F 9400 Low Application Temperature (LAT) FBE Series for Stand-Alone & for Multi-Layer System.National Paints introduces NextGen NP-F 9400 Low Application Temperature (LAT) series to overcome this problem. NP-F 9400 Series can be used as single layer stand-alone coatings, and can also be used as primer in multi layer system. NP-F 9400 normally applied in the temperature range 180°C to 200°C as a stand-alone anti corrosion coating, NP-F 9400 is extremely reactive and can be applied at higher rate in 3-layer system in the temperature range 160°C to 180°C.
