Surface Preperation
Abrasive blasting to Sa 21/2 Swedish Standards is the best method of surface preperation. In case blasting is not possible, then the surface of steel should be cleaned to St – 2/St – 3. The surface should be absoultely dry, moisture 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 –resinoustopcoats.
Application Method
Stir the base part thoroughly. Mix the base and hardener as per our recommended ratio by volume. Stir the mix genlty 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 throught Nylon filter cloth 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 required for Brush applications, however under adverse enviornmental conditions about 5% of thinner, by volume can be added. 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. DFT variation can be obtained by change in application method / thinning ratio. Contact Khodal Paints representatives for further assistance.
4. Shelf life indicated is minimum for this Prodcut 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.
