Description

AFCICOAT series of highly thixotropic refractory coating with in built anti fungus and anti settling properties specially recommended for a good surface finish and dimensional accuracy for ferrous and non ferrous castings.

AFCICOAT is available in slurry form having excellent fluidity characteristics can be achieved by dilution from

20 – 40 % to specified viscosity as per individual application need.

AFCICOAT is also available in paste & powder form

ADVANTAGES :

  1. Superior suspension properties.
  2. Deep penetration of dressings into the pores of the sand.
  3. Excellent coverage, uniform coatings.
  4. Versatility of Application – Spray, swab, or dip.
  5. Freedom form cracking – reduced tendency of the coating to crack either during drying or at elevated temperatures.
  6. Elimation of Metal/ Mould reactions.
  7. Good antifungus and thixotropic properties.
  8. No synerisis / No run out.
  9. Low gas evolution during pouring
  10. Smooth castings finish and dimensional accuracy
  11. Economical due to reduced fettling and cleaning cost

WHY USE DRESSINGS:

  • To prevent erosion of Sand during metal flow.
  • To increase the sales appeal of your castings.
  • To increase the life of machining tools.
  • To reduce fettling costs.

INSTRUCTION FOR USE:

AFCICOAT must be thoroughly stirred & shaken before being used & the lid should be replaced on the container immediately after use. Afcicoat may be sprayed, brushed / swabbed or dipped on to the mold or core surface to be treated.

OVEN DRYING  –

After application, the treated surfaces of moulds or cores are kept   in the oven starting from 30 O to 160 O C 7 later taken out & kept outside for air drying & this is generally complete within about 1-1 ½ hour in case of oven drying & later moulds can be closed & cast immediately.
