Sherwin-Williams Epo-Phen FF

Sherwin-Williams Epo-Phen FF coating is a flake-filled (MIO) amine cured epoxy phenolic novolac formulated for use under thermal insulation at elevated or cryogenic temperatures and for immersion service in water and hydrocarbons such as gasoline, fuel oil, and diesel fuel. 

Features & Benefits

• Temperature resistant to 218°C (425°F), constant;  232°C (450°F) intermittent (dry service)
• Self priming
• Chemical resistant

The micaceous iron oxide (MIO) provides:

• High temperature resistance
• Film reinforcement
• One coat, high build application
• Improved edge protection

Recommended Uses

• Steel and stainless steel tanks and piping under insulation
• Non-insulated structural steel and piping subjected to chemical or abrasion attack
• Use in areas subject to wet/dry cycling up to 149°C (300°F)
• Use in areas where temperature resistance up to 232°C (450°F) is required (dry service)
• Acceptable for use in immersion service at elevated temperatures for fresh water and distilled water 99°C (210°F)
• Suitable for storage of gasoline, fuel oil, diesel fuel, and other similar hydrocarbon cargos
• Not qualified for potable water immersion
• Water and wastewater facilities
• Wind tower gearbox lining

Performance Tips

Stripe coat crevices, welds, and sharp angles to prevent early failure in these areas.

When using spray application, use a 50% overlap with each pass of the gun to avoid holidays, bare areas, and pinholes. If necessary, cross spray at a right angle.

Spreading rates are calculated on volume solids and do not include an application loss factor due to surface profile, roughness or porosity of the surface, skill and technique of the applicator, method of application, various surface irregularities, material lost during mixing, spillage, overthinning, climatic conditions, and excessive film build.

For Immersion Service: (if required) Holiday test in accordance with ASTM D5162 for steel, or ASTM D4787 for concrete.

Excessive reduction of material can affect film build, appearance, and adhesion.

Do not mix previously catalyzed material with new.

Do not apply the material beyond recommended pot life. In order to avoid blockage of spray equipment, clean equipment before use or before periods of extended downtime with Reducer #15.

Temperatures above 25°C (77°F) will shorten the pot life.

Do not apply over 225 microns (9.0 mils) total dft when used in service above 149°C (300°F).

Not recommended for potable water immersion.

Acceptable for insulation to be applied over the coating, after the coating has reached it's dry to touch time.
