Saffro Mellow Coatings And Resins



Two component metallic zinc rich epoxy high performance primer.

Recommended Use :-

The zinc pigment in dry film renders excellent protection to steel structure, tanks, bullets, dam gates, pipelines, plant equipments, jetty, etc. in both interior and exterior exposed conditions of fertilizer units, chemical plants, steel plants, cement plants, pulp and paper industries, ports, power plants, petrochemical and pharmaceutical industry, transformer, machines & other heavy duty OEMs. It also provides cathodic protection to steel and gives good resistance to corrosion at local damaged areas. It is useful in heavy-duty protective paint systems. It is recommended not to expose the primed coat alone to chemical and saline atmosphere for a long time.

Physical Data

THEORETICAL SPREADING RATE : 10 sq.mt / ltr at DFT of 50 µ
FLASH POINT : Base : Above 23°C Hardener : Above 23°C
DRYING CHARACTERISTICS (at 30°C & at 65% Relative Humidity) : HARD DRY : Overnight FULL CURE : 7 days
SHELF LIFE : BASE : 6 months HARDENER : 6 months

Surface Preparation

Abrasive blasting to minimum Sa 2 1/2 Standards is recommended with a profile of 35 - 75 microns. The surface should be absolutely dry and salt free before application. The primer should be applied preferably immediately or within 4 hours of blasting.

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 : 4 hours min at 30°C
COMPATIBILITY : Compatible with Epoxy, PU, Chlorinated Rubber intermediate/finish coat.

Application Method

Stir the Base part thoroughly with power stirrer. Mix the base and hardener as per our recommended ratio, by volume. Stir the mix gently to attain homogeneity. Add Epoxy Thinner into the mix, depending on application method, and stir gently for few minutes. Allow the mixture to stand still (maturation) for about 10-15 minutes to initiate the reaction. Strain the paint through Nylon filter cloth and apply uniformly over the surface. All equipments used for above should be properly clean.

Application: By Brush / By Conventional Spray / By Airless Spray Generally brushing is not recommended. However for small /touch up area with 5% max. Thinner addition it can be used. . Apply evenly in crossed manner ensuring 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 psi.

For Airless Spray application :-

Thinner : Epoxy Thinner 190
Addition : Max 5% if required

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 and Zinc contents are also available on requests.
4. Product for flow coat applications is also available on request.
5. DFT variation can be obtained by change in application method/thinning ratio.
6. 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.
