BASIC DATA

SURFACE PREPARATION

Coating performance is, in general, proportional to the degree of surface preparation.

Abrasive blasting is usually the most effective and economical method.When this is impossible or impractical, Amerlock 2 can be applied over mechanically cleaned surfaces. All surfaces must be clean, dry and free of all contaminants, including salt deposits. Contact PPG for maximum allowable salt containment levels.

Mild Steel

Remove all loose rust, dirt, grease or other contaminants by one of the following depending on the degree of cleanliness required: SSPC-SP2, 3, 6, 7 or 10 (ISO 8501-1 St-2, St-3, Sa 1, Sa 2.5). These minimum surface preparation standards apply to steel that has been previously abrasive blasted. The choice of surface preparation will depend on the system selected and end-use service conditions.

For more severe service and immersion, clean to SSPC-SP10 (ISO8501-1 Sa 2.5). Blast to achieve an anchor profile of 1.0-5.0 mils (25-125 microns) as indicted by a Keane-Tator Surface profile Comparator or Testex Tape. Previously blasted steel may be ultra-high pressure water jetted to SSPC SP WJ-2(L) / NACE WJ-2(L).

The wet surface can be dried by blowing with dry compressed air giving special at- tention to horizontal surfaces and recesses.

Concrete

Prepare / clean surface in accordance with SSPC SP-13 guidelines. Abrade surface per ASTM D-4259 to remove all efflorescence and laitance, to expose sub-surface voids, and to provide a surface roughness equivalent of 60 grit sandpaper or coarser. Test for moisture by conducting a plastic sheet test in accordance with ASTM D4263. Fill voids as necessary with Amercoat 114A epoxy filler. For slabs on grade, test for moisture in accordance with ASTM F1869 (calcium chloride test).

The maximum allowable moisture transmission is 3 lbs / 1,000 ft2/24 hours. Refer to Information Sheet 1496ACUS for further details regarding moisture measurements.

Galvanized Steel

Remove oil or soap film with detergent or emulsion cleaner. Lightly abrasive blast with a fine abrasive in accordance with SSPC SP-16 guidelines to achieve a profile of 1.5-3.0 mils. When light abrasive blasting is not possible, galvanizing can be treated with a suitable zinc phosphate conversion coating. Galvanizing that has at least 12 months of exterior weathering and has a rough surface with white rust present may be over-coated after power washing and cleaning to remove white rust and other contaminants. The surface must have a measurable profile. A test patch is recom- mended to confirm adhesion. Not recommended over chromate sealed galvanizing without blasting to thoroughly remove chromates. Adhesion problems may occur.

Non-Ferrous Metals and Stainless Steel

Abrasive blast in accordance with SSPC SP-16 guidelines to achieve a uniform and dense 1.5-4.0 mil anchor profile. Size and hardness of abrasive should be adjusted as necessary based on the hardness of the substrate. Aluminum may be treated with a surface treatment compliant with Mil-DTL-5541 or equivalent (non-immersion applications only).

Aged coatings

All surfaces must be clean, dry, tightly bonded and free of all loose paint, corrosion products or chalky residue. Abrade surface, or clean with Prep 88. Amerlock 2 is compatible over most types of properly applied and tightly adhering coatings, however, a test patch is recommended to confirm compatibility.

Repair

Prepare damaged areas to original surface preparation specifications, feathering edges of intact coating. Thoroughly remove dust or abrasive residue before touch-up.

ENVIRONMENTAL CONDITIONS

Ambient temperatures*

• 20°F to 122°F (-6°C to 50°C)
• *Amerlock 400 hardener can be used with the Amerlock 2/400 base component for applications that require a long pot life. The A component is the same for Amerlock 400 and Amerlock 2. The B components are inter- changeable.

Material temperatures

• 40°F to 90°F (5°C to 32ºC)

Relative humidity

• 0 to 100%, surface must be free of visible moisture. For immersion service and for optimum performance, surface temperature must be at least 5°F above the dew point temperature.

Surface temperature

• 20°F to 122 °F (-6°C to 50°C)
• Amerlock 2 may be applied to surfaces as hot as 250°F (121°C) for non-immersion service. When applying Amerlock 2 to surfaces between 122°F and 250°F,
• Amerlock 2 must be thinned at 1/2 pint per gallon with only
• Amercoat 101 Multiple thin passes may be required to achieve film build and to avoid solvent blistering.

General air quality

Area should be sheltered from airborne particulates and pollutants. Avoid combustion gases or other sources of carbon dioxide that may promote amine blush. Ensure good ventilation during application and curing. Provide shelter to prevent wind from affecting spray patterns. Refer to Information Bulletin #1489 for further information on prevention, detection, and mitigation of amine blush.

INSTRUCTIONS FOR USE

DRYICURE TIMES

Amerlock 2 @ 5 mils dft

Amerlock 2 Aluminum @ 5 mils dft

Dry times are dependent on air and surface temperatures as well as film thickness, ventilation, and relative Maximum recoating time is highly dependent upon actual surface temperatures – not simply air temperatures. Surface temperatures should be monitored, especially with sun-exposed or otherwise heated surfaces. Higher surface temperatures shorten the maximum recoat window. An extended recoatable window may be allowable in some circumstances. Please contact your PPG PMC representative for more details.

• Surface must be clean and dry. Any contamination must be identified and removed. A detergent wash with Prep 88 or equivalent is required prior to application of topcoats after 30 days of exposure. However, particular attention must be paid to surfaces exposed to sunlight where chalking may be present. In those situations, a further degree of cleaning may be required. PPG Technical Service can advise on suitable cleaning methods. If maximum recoat/topcoat time is exceeded, then roughen surface.
