Saffro Mellow Coatings And Resins



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 :-

THEORETICAL SPREADING RATE : 13.33 sq.mt. / ltr. at DFT of 30 µ
FLASH POINT : Base : Above 23°C Hardener : Above 23°C
DRYING CHARACTERISTICS (At 300 C & 65% Relative Humidity) : 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
THINNER : Epoxy Thinner 190
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 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.

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.


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 SAFFRO's recommended thinner otherwise equipment is liable to be damaged.
3. DFT variation can be obtained by change in application method/thinning ratio.
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 mist or vapours as well as contact between the wet paint and exposed skin or eyes.
