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:
| |||||||||
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. |
