ASFOCOAT-160 (Spray Cleaning-cum-Phosphating Process)

DESCRIPTION:  

Our ASFOCOAT-160 alongwith ASFOCLEAN-140 used together gives excellent cleaning as well      as an extremely fine complex phosphate coating ideally suited for ferrous sheet metals prior to painting.  The phosphate coating obtained is in the range of 30-50 mg/sq.ft. which gives very good adhesion of paints.  This spray process is most suitable for large  size  metallic  sheets, rolls  or  files, bus bodies, assemblies of vehicle bodies, drums and barrels, and or parts which are inconvenient to handle  and process under dip system.  This process is also suitable for internal lacquering of drums and barrels.
