Surface Preparation

Abrasive blasting to SA 2 1/2 Swedish Standards is the best method of surface preparation. In case blasting is not possible, then the surface of steel should be cleaned to St-2/St-3 std. The surface should be absolutely dry, moist and oil free before primer application.

Application Data

Mixing Ratio : Base : Hardener – (As per our recommendations)
Application : By Brush / By Conventional Spray / By Airless Spray
Thinner : Type 002
Pot life : 4 hours min at 30° C
Recommended Dft : 30 – 40 µ.
Overcoating Interval :
  • Min. : 8 hours
  • Max.: 24 hours
Compatibility : Can be over coated with Epoxy, PU, Chlorinated rubber and Oleo-resinous topcoats

Application Method

Stir the base part thoroughly with. Mix the base and hardener as per our recommended ratio by volume. Stir the mix gently to attain homogeneity. Allow the mixture to stand still (maturation) for about 10-15 minutes to initiate the reaction. Add thinner type 002 into the mix, if required depending on the application method and then stir gently for few minutes. Strain the paint through Nylon filter cloth of 100 mesh size and apply uniformly over the surface. All equipment used for above should be properly cleaned.

Application : By Brush / By Conventional Spray / By Airless Spray

Generally no thinner is reqired for Brush application, however under adverse environmental conditions about 5% thinner by volume. Apply evenly in crossed manner ensuring the uniform application. Use quality brushes for paint application.

For Conventional Spray application:
  • Thinner : Type 002
  • Addition : 10-15%
  • Nozzle Orifice : 1.2 – 1.4mm
  • Nozzle Pressure: 40 – 70 p.s.i.
For Airless Spray application :
  • Thinner : Type 002
  • Addition : Max 5%, if required
  • Nozzle Orifice : 0.37mm – 0.42mm
  • Nozzle Pressure : 1400 -1800 p.s.i.

Notes

  1. Do not apply paint when temperature falls below 10° C or rises above 50° C and when Relative Humidity is above 85%. Do not apply during rain, fog or mist. Surface temperature must always be minimum of 3° C above Dew point.
  2. Brushes and spray equipment should be cleaned with KP’s recommended thinner otherwise equipment is liable to be damaged.
  3. Products with different volume solids, with Amine Hardener and also Ld/Crfree version are available on requests
  4. Product for flow coat applications is also available on request.
  5. DFT variation can be obtained by change in application method / thinning ratio. Contact Khodal Paints representatives for further assistance.
  6. Shelf life indicated is minimum for this Product in sealed conditions and it is subject to re-inspection thereafter. Individual component is required to be stored in cool, dry and covered condition away from heat and ignition.

Health & Safety

This is a solvent based paint and care should be taken to avoid inhalation of spray or eyes. Mist or vapours as well as contact between the wet paint and exposed skin.
