| 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. For low temperature application, use Amercoat 861 accelerator. Do not exceed the 1 pint Amercoat 861 accelerator per 5 gallon unit recommendation. | |||||||||
| 4. | Do not mix more material than can be used within the expected pot life. | |||||||||
| 5. | For optimumapplication,material should be from50° to 90 °F (10° to 32 °C). Above 122 °F (50 °C), saggingmay occur. | |||||||||
| 6. | Use only PPG recommended thinners. For potable water applications, see current NSF listing atwww.nsf.org for approved thinners and thinning restrictions. For other applications, above 85 °F (29 °C) use Amercoat 8, or 101 at lower temperatures use Amercoat 65. A small amount of thinner greatly reduces viscosity; excessive thinning will cause running or sagging. Thin cautiously as follows:
Below 50 °F additional thinning may be needed and multiple coats required to achieve specified thickness. Above 122 °F, up to 250 °F surface temperatures, use Amercoat 101 thinner sparingly to promote flow and leveling. Excessive thinning will cause running or sagging. | |||||||||
| 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 passes with 50 percent overlap to avoid holidays, bare areas and pinholes. If required, cross spray at right angles. | |||||||||
| 9. | When applying Amerlock 400 directly over inorganic zincs or zinc rich primers, amist coat/full coat technique may be required to minimize bubbling. This will depend on the age of the Dimetcote, surface roughness and conditions during curing. | |||||||||
| Note . Do not use Amerlock 400AL onwater damp surfaces | ||||||||||
| 10. | Ventilate confined areaswith clean air between coats 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. | |||||||||
