PRODUCTS FUNCTION APPLICATION
CRAFTCOTE-CEN Insulating coating CRAFTCOTE – CEN is recommended for all C.I. Casting. It can be applied by dipping / brushing application. Thick coating to be applied to get good insulating effect. The insulating property of coating reduces the solidification rate of metal. Recommended for reducing the chilling / hardening of metal at thin wall section casting.  After  applying  coating air dry it for 10 to 20 minutes and then dry in oven at 150°C to
160 °C for min. 20 minutes or by torching.To insure moisture free.
CRAFTCOTE-CEN(M) Centrifugal dicasting coating Ensure that die is free from foreign  material and dust.  Stir  the coating and dilute it by ratio 100:5  to 100:10 ( i.e. product : water).  Apply by spraying on hot die (at die temperature 150° C to 180° C) and coat up to 1mm thickness.  If thickness is not achieved in one spray, apply  again.  Keep the die rotating while spraying CRAFTCOTE – CEN (M), so as to get uniform coating thickness.   Now pour the metal.

After removing casting, again clean the die surface and apply coating by
same  procedure.

CRAFTCOTE-SN Special Inoculation Coating Apply CRAFTCTOE - SN as it is on sand mould/core by brushing. If the permeability of sand is more then we recommend to have a precoat with zircon or other mixed refractory water based coating. Dry the coating and then apply CRAFTCOTE- SN. Dry it in oven at 120° C for 1 hr. Ensuring removal  of moisture from the coating. Mould/ Core is then ready for pouring. Do not apply other coating on CRAFTCOTE- SN.
CRAFTCOTE-TE SPECIAL  CHILLING COAT
  1. CRAFTCOTE - TE is to be applied as it is by brushing or swabbing after uniform mixing. If required coating can be further diluted with water in case thinner coating consistency is needed.
  2. Mould or core should be thoroughly dried before pouring the metal. (Do not heavily torch the coating) .
  3. Whenever double coating is required take care that the previous coat is thoroughly air dried.
CRAFTCOTE-TES CHILLING COAT
  1. CRAFTCOTE – TES is to be applied as it is by brushing or swabbing after      uniform   mixing.
  2. Mould or core should be thoroughly dried before pouring the metal. (Do not heavily torch the coating).
  3. Whenever double coating is required take care that the previous coat is thoroughly air dried.
  4. For economical practice, give first coat of zircon base coating on the portion when CRAFTCOTE – TES is to be used.
