Surface Preparation
Abrasive blasting to Sa 21/2 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, moisture and oil free before primer application.

Application Data
MIXING RATIO : Base : Hardener (As per our recommendations)
APPLICATION : By Brush / By Conventional Spray
THINNER : Epoxy thinner 190
POT LIFE : 4 hours min at 30 C
RECOMMENDED DFT : 30 - 40 au.
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. 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 Epoxy Thinner into the mix, if required, depending on application method, and stir gently for few minutes. Strain the paint through Nylon filter cloth of 100 mesh size and apply uniformly over the surface. All equipments used for above should be properly cleaned.

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 criss-cross manner and ensure the uniform application. Use quality brushes for paint application
