Surface Preparation

This being intermediate/finish paint, it is applied either over primer. The surface should be free from moisture, oil and dust before application. In case of aged epoxy coating/exceeded over coating, the surface should be sufficiently roughened prior to painting.

Application Data

MIXING RATIO : Base : Hardener (As per our recommendations)
Application : By Brush / By Conventional Spray / By Airless Spray
Thinner : Type 001
Pot Life : 4 hours min at 30° C
Recommended dft : 35 – 35 µ.
Overcoating interval :
  • Min. : 8 hours
  • Max.: 24 hours
Compatibility : Can be top coated by Epoxy, PU, Chlorinated Rubber and synthetic enamel paints. Compatible with Epoxy and zinc rich primers.

Application Method

Stir the Base part thoroughly. Mix the base and hardener in the recommended ratio by volume. Stir the mix thoroughly to attain homogeneity. Add thinner Type 001 into the mix, if required, depending on application method and stir thoroughly for few minutes. Allow the mixture to stand still (maturation) for about 10 minutes to initiate the reaction. Strain the paint through Nylon filter cloth and apply uniformly over the surface. All equipments used for above should be properly clean.

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

Generally no thinner is required for Brush application, however under adverse environmental conditions about 5% of thinner, by volume can be added. Apply evenly in crossed manner and ensure the uniform application. Use quality brushes for paint application.

For Conventional Spray application:
  • Thinner : Type 002
  • Addition : 5-15%
  • Nozzle Orifice : 1.2 – 1.4 mm
  • Nozzle Pressure: 40 – 70 p.s.i.
For Conventional Spray application:
  • Thinner : Type 002
  • Addition : Max 5%, if required
  • Nozzle Orifice : 0.28 – 0.37 mm
  • Nozzle Pressure: 1400 – 1800 p.s.i.

Notes

  1. Do not apply paint when temperature falls below 10° C or rises above 50° C when is above 85% & 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. DFT variation can be obtained by change in application method / thinning ratio. Contact Khodal Paints representative for further assistance
  4. 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.
