Asfocoat -Mn

Phosphate treatment of metals or Phosphating, as it is commonly termed in the metal finishing industry has been acclaimed as one of the most useful and effective method for the protection of iron and steel surfaces from atmospheric corrosion. It is manganese phosphating chemicals. Apart from its anti-rust character, the coating provides an ideal base for an organic finish and as an aid to lubrication. It also prevents wear in sliding or frictional parts. The coating provides myriads of oil reservoirs effective in reducing friction.

Performance:
ASFOCOAT-MN is of Manganese Phosphate type and mainly used for producing corrosion resistant phosphate coating as well as lubricating and wear resistant surface under a dip type system. It produces dark grey coatings of the order of .002 mm for light coatings and .005 mm or more for heavy coatings weighing from 800 mgs per sq.ft. of surface area, to higher than 2,000 mgs per sq.ft. as per desired specifications to meet class A1 coating under I.S. 3618.

Application:
Piston Rings, Rocker Arms, Gears, Valves, Tappets, Cylinder Lines, Camshafts, Nuts & Bolts, Small Arms and Defense Equipment and other machinery spare parts are frequently phosphates to increase life, by reducing Wear and Friction.
