Recommended

Dry film thickness (per coat) 0.75 – 2.0 mils; (15 – 35 microns)

1 or 2 coats

Theoretical Spread Rate @ 1 mil dft 497 ft2 / gallonComponents 1

Shelf Life 2 years from date of manufacture

SURFACE PREPARATION

Steel – Remove weld spatter, protrusions, and laminations in steel. Grind welds smooth in

accordance with NACE RP-0178. Round off sharp edges. Remove all surface con-

taminants, oil and grease in accordance with SSPC SP-1.

Abrasive blast with an angular abrasive to an SSPC SP-10 cleanliness or higher.

Achieve a surface profile of 1.0-1.5 mils. Apply Amercoat 3279 as soon as possible

to avoid rusting of blasted surfaces.

Stainless Steel – Abrasive blast with a hard angular abrasive to achieve a uniform and dense anchor

profile of 1.0-1.5 mils.

Inorganic Zinc Surfaces – Surface must be clean, dry and free of zinc salts. A mist coat / full coat applicationtechnique may be required to prevent application bubbling.

ENVIRONMENTAL CONDITIONS

Ambient temperatures* 32°F to 104°F (0°C to 40°C)

Material temperatures 50°F to 90°F (10°C to 32ºC)

Relative humidity 0 – 85%

Surface temperature 32°F to 104°F (0°C to 40°C) Surface temperature must remain at least 5°F above the

dew point temperatures.

General air quality Area should be sheltered from airborne particulates and pollutants. Provide shelter to

prevent wind from affecting spray patterns.

INSTRUCTIONS FOR USE

Mixing Mix with a pneumatic air mixing at moderate speeds to homogenize the container.

Airless spray 33:1 pump or larger, 0.017 fluid tip

Air spray Use a 2.0-2.6 mm fluid tip at approximately 40 psi fluid pressure. An agitated pressure

pot is recommended. Separate air and fluid regulators are essential. Ensure there is a

moisture and oil trap in the main air line.

Brush & roll Spray application is recommended as the best method to obtain a closed film within the

film thickness limits. Rolling may leave visible patterns in the film. A short nap, solvent

resistant roller is required.

Use a high quality natural bristle brush. Ensure brush is well loaded to avoid air entrain-

ment. Brush application is limited to small touch up areas of a few square inches.

Thinner Amercoat 65

Cleaning solvent Amercoat 12 Cleaner or Amercoat 65 thinner

Safety precautions For paint and recommended thinners see safety sheet 1430, 1431 and relevant material

safety data sheets

This is a solvent borne paint and care should be taken to avoid inhalation of spray mist

or vapor as well as contact between the wet paint and exposed skin or eyes.

DRY/CURE TIMES*

* Product is not designed for heavy mechanical abuse. Care should be taken during shipping and handling.Make any necessary repairs prior to service. Coating film will become more durable after exposure to high

temperatures.
