Application Procedure
1.Flush all equipment with thinner or Amercoat 12 before use.
2.Stir resin and cure using an explosion-proof powermixer to disperse pigments.
3.Add cure to resin. Mix thoroughly until uniformly blended to a workable consistency.
4.Do not mix more material than can be used within the expected pot life.
5.For optimum application, material should be from 50° to 90°F (10° to 32 °C). Above 122 °F (50 °C), sagging may occur.
6.Use only PPG recommended thinners. For potablewater applications, see current NSF listing at www.nsf.org for approved thinners and thinning restrictions. For other applications above 85 °F (29 °C) use Amercoat 8 or Amercoat 101, at lower temperatures use Amercoat 65. A small amount of thinner greatly reduces viscosity; excessive thinningwill cause running or sagging. Thin cautiously as follows:
Amerlock 2Amerlock 2AL
Airless - up to½ pt/gal1pt/gal
Conventional - up to½ pt/gal1pt/gal
Below 50 °F additional thinning may be needed and multiple coats required to achieve specified thickness.
7.To minimize orange peel appearance, adjust conventional spray equipment to obtain adequate atomization at lowest air pressure.
8.Apply a wet coat in even, parallel passeswith 50 percent overlap to avoid holidays, bare areas and pin holes. If required, cross spray at right angles.
9.When applying Amerlock 2 directly over inorganic zincs or zinc rich primers, a mist coat/full coat techniquemay be required to minimize bubbling. This will depend on the age of the Dimetcote, surface roughness and conditions during curing.
10.Ventilate confined areas with clean air during application and while curing the final coat. Prevent moisture condensation on the surface between coats.
11.Repair damaged areas by brush or spray.
12.Clean equipment with thinner or Amercoat 12 immediately after use.
Note: Do not apply Amerlock 2AL on water-damp surfaces.
