Description

Two component Epoxy based anticorrosive primer containing red oxide and zinc phosphate as corrosion inhibiting pigments

Recommended Use :-
This product is 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 corrosion 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. / ltr. at DFT of 30 �µ
FLASH POINT : Base : Above 23�°C Hardener : Above 23�°C

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 30C
RECOMMENDED DFT : 30 - 40
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.

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. Add Epoxy Thinner Thinner into the mix, if required, depending on application method, and stir gently for few minutes. Strain the paint through Nylon filter cloth and apply uniformly over the surface. All equipments used for above should be properly clean.
