ASFOCOAT-K : 

process operated at room temperature produces a fine grain smooth and continuous Zinc Phosphate conversion coating for pre-paint treatment of steel. Applied by dip, it protects the base metal against corrosion and bonds supplementary coatings firmly to the surface. The chemically converted phosphate coating provides an excellent foundation for the lasting adhesion of paint.

Process:

Sr. No Stage Chemical Concentration Temperature Time (minutes) Tank
1 Degrease ASFOCLEAN-B 5 - 10% (w/v) R.T. - 70?C 10/20/10 *M.S./Plastic

3 Derust SCALGUN / RUST SOLVENT 15% - 25% (v/v) R.T. 10/30/10 Plastic or FRP lined M.S.
4 Rinse WATER - R.T. 1 M.S./Plastic
5 Activate ASHPREP (Optional) 0.5% (w/v) R.T. 1 M.S./Plastic
6 Phosphate + Additive ASFOCOAT-K + ACCELERATOR 8% - 10% (v/v) 0.2%-0.3% (w/v) R.T. 25 - 35
7 Rinse WATER - R.T. 1
8 Passivate ASFOFIX-A 0.025% (v/v) R.T. - 70?C 1 *M.S./Plastic
9 Dry-off immediately with help of hot air blower or compressed air under a fan.

Notes :

  • While preparing any bath, always add chemical to water
  • While preparing phosphating bath, first add the required amount of chemical to water and then add ACCELERATOR as stated below
  • ACCELERATOR should always be dissolved separately in a small quantity of water and this solution is then sprinkled uniformly in the Phosphating bath
  • False bottom should be provided in each tank to avoid parts from touching the bottom and to maintain bath free from sludge interference
  • Phosphating bath should be decanted periodically to remove sludge settled at the bottom of the tank
  • Manual swabbing with the degreasing solution is advisable for heavy oily contamination
  • The quality and uniformity of the phosphate coating is directly dependent on the pre-treatment prior to phosphating. It is essential that the parts are absolutely free of oil, rust, dust,scales and other contaminants before immersing in the phosphating bath
  • pH of passivating bath should be maintained between 3 & 5. Passivating bath should be discarded periodically and made fresh
  • Additions to all chemical tanks should be made daily and regularly to obtain consistently uniform results.All rinse water baths should be made fresh at least twice a week
  • Activation with ASHPREP at 0.5% produces a compact dense zinc phosphate coating

ASFOCOAT-ZX process is operated at higher temperature by dipping method to produce a smooth and continuous fine grain Zinc Phosphate conversion coating. This coating improves adhesion between paints and steel and also protects steel from under-paint corrosion thus enhancing life and durability of paints.

Uses:

ASFOCOAT-ZX process is used on all steel surfaces which are to be painted or powder coated. It is also used on ground and machined components etc. to produce medium to heavy weight zinc phosphate coating which is then sealed with rust preventive such as ASFOSIL DW-56. This process is ideally suited to produce dark grey to black phosphate coating on nut bolts and fasteners.

  • Heating in tanks 1, 5 & 7 should only be done from the sides of the tank and not from the bottom
  • Heavily contaminated sheets and parts must be dipped/swabbed with kerosene or degreasing bath solution before dipping in the degreasing bath
  • In most continuous processes it is necessary to have a hot spray knock-off with ASFOCLEAN-SP prior to degreasing or have two dip degreasing stages using STRIPPER-HD

Sealing:

Phosphated parts which are not to be painted should be dipped in ASFOSIL-DW56 for long term protection against corrosion.

Safety Precautions:


  • PVC/Rubber gloves, aprons and eyeshields should be worn while handling chemicals
  • Splashes or splatters on eyes or skin should be washed off with plenty of fresh water

ASFOCOAT-DRP is a liquid chemical product used for surface preparation of metals before painting. The objective of treating metals with Asfocoat-DRP, before painting is to prolong the life of paints by offering it a “compatible” surface to which it will be locked. Asfocoat-DRP removes oils, rust, soils, etc. and forms a phosphate coating integral with metal surface.

Pretreating metals with Asfocoat-DRP offers the following advantages :-

  1. Prevents under paint corrosion

  2. Prevents spreading of rust from a damaged area to sound area adjoining it

  3. Increases paint adhesion with metal substrate

  4. Prevents paints from peeling or flaking off

  5. Enhances durability and life of paints

 

Aasfocoat-DRP can be easily applied by swab, brush or dip after dilution with water at room temperature. After 2-3 minutes, the surface is simply wiped dry with a cloth. The surface is now ready to accept any type of paints or primers. Asfocoat-DRP can be applied on any ferrous metals. Few applications are on steel furniture such as chairs, tables, cupboards, cabinets, safes, lighting patties, luminaries, printers, copiers, duplicators, computer systems, typewriters boilers, heat exchangers, coolers, air conditioners, slotted angles and various other equipment machineries and fabrications, that are to be painted/or powder coated.

Asfocoat-DRP is available in 3 standard packings of 6, 12 & 40 kgs. Asfocoat-DRP is manufactured by Ashok industry since 1960 and it is an ISO 9001-2015 certified company.
