Saffro Mellow Coatings And Resins



Two component, air drying, high solids, Epoxy coating. The product has the advantage of epoxy resin composition with speciality pigment, which facilitates one-coat, high build application for high performance. The product can be applied on minimum prepared surface and is designed to completely wet the substrate. Excellent adhesion is obtained on a variety of intact surfaces including over old coating and tightly adherent rust. The composition has been balanced to a convenient mixing ratio by volume with excellent application characteristics. The ZERO solvent content reduces the problem of lifting of the paint film and adhesion failure by blistering and pin holing. This assures a stable long term performance.

Recommended Use :-

It is mainly recommended in those areas where blasting is impractical or impossible. Uses include steel structures in Industrial plants, bridges, tank exteriors, oil tanks, pipes, marine atmosphere, cooling towers, etc. It has good resistance to spillage and fumes of acids, alkalis, fresh and salt water. 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, water tank, pipelines etc. for application on tank exteriors and interiors, structural steel, pipelines, machineries, vessels, etc.

Physical Data

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) : Base : Hardener (As per our recommendation)
APPLICATION : By Brush / By Airless Spray
POT LIFE : 2 - 3 hours min at 30° C
RECOMMENDED DFT : 75-100 mic.
OVERCOATING INTERVAL : MIN : 8 hours MAX : 24 hours
COMPATIBILITY : Can be over coated with Epoxy, PU

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 EpoxyThinner 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 uniformity. Use quality brushes for paint application.

For Conventional Spray application :-

Thinner : Epoxy Thinner 190
Addition : Max 10 - 15%
Nozzle Orifice : 2-3 mm
Nozzle Pressure : 40-70 psi.

For Airless Spray application :-

Thinner : Epoxy Thinner 190
Addition : Max 5%, if required.
Nozzle Orifice : 0.48-0.53 mm
Nozzle Pressure : : 2700-3200.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. Products with different volume solids, MIO pigmented also with Amine Hardener are available on requests
4. DFT variation can be obtained by change in application method / thinning ratio.
5. Shelf life indicated is minimum for this Product in sealed condition and it is subjected to re-inspection thereafter. Individual component is required to store 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.
