Description Two component Epoxy based anti corrosive primer containing red oxide and zinc chromate as corrosion inhibiting pigments Recommended Use :- Recommended as a primer on suitably cleaned mild steel surface in various fertilizer units, refineries, chemical and other plants, transportation industries, steel plants, cement plants, power plants, pulp and paper industries, pharmaceutical industries, etc. for application on tank exteriors, structural steel, pipelines, machineries, vessels, etc. The product is recommended as a primer for mild to moderate service conditions. Not to be recommended for immersed water condition Physical Data COLOUR : Red FINISH : Matt SOLIDS BY VOLUME : 40 + 3% THEORETICAL SPREADING RATE : 13.33 sq.mt / lt at recommended DFT of 30 FLASH POINT : Base : Above 23C Hardener : Above 23C DRYING CHARACTERISTICS (At 65% Relative Humidity & at 30C) : SURFACE DRY : 60 - 90 minutes HARD DRY : Overnight FULL CURE : 7 days SHELF LIFE : BASE : 6 months HARDENER : 6 months 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 / By Airless Spray THINNER : Epoxy Thinner 190 POT LIFE at 30�°C : 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 Synthetic Enamel finish paints. 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 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, ensuring the uniform application. Use quality brushes for paint application. For Conventional Spray application :- Thinner : Epoxy Thinner 190 Addition : 10-15% Nozzle Orifice : 1.2 -1.4 mm Nozzle Pressure : 40-70 p.s.i. For Airless Spray application :- Thinner : Epoxy Thinner 190 Addition : Max 5% if required Nozzle Orifice: 0.37- 0.42mm Nozzle Pressure : 1400-1800 p.s.i.
