Tank Coating System – Two coats of Amercoat 235 at 4 to 8 mils (100 to 200 microns) per coat, plus two stripe coats over sharp edges, cutouts and welds. Use contrasting colors for each coat and stripe coat. Minimum (hours) Amercoat 235 Amercoat 229 Series 90/32 2 3. Flush all equipment with thinner or Amercoat 12 before use. Stir base using an explosion-proof power mixer to disperse pigments. Add cure to resin. Mix thoroughly until uniformly blended to a workable consistency. Induction time 70°F/21°C 15 minutes: 4. Do not mix more material than can be used within the expected pot life, 41.2 hours. Minimum 28:1 ratio pump; 0.018' - 0.021' (475-533 microns) orifice tip; 3/8' ID high pressure material hose; 60 mesh tip filter DeVilbiss MBC-510 gun E tip and 704 air cap; 3/8' (9.5 mm) ID material hose; double regulated pressure tank with oil and moisture separator. APPLICATION Mixing Airless Spray Conventional Spray Brush Roller Thinner. Add cure to resin. Mix thoroughly until uniformly blended to a workable consistency. Induction time (at 21°C/70°F): 15 minutes. Do not mix more material than can be used within the expected potlife, 90 min at 21°C/70ºF. Higher material temperatures will shorten the potlife considerably.

| Application Procedure |
| 1. | Flush all equipment with thinner or Amercoat 12 before use. |
| 2. | Stir base using an explosion-proof power mixer to disperse pigments. |
| 3. | Add cure to resin. Mix thoroughly until uniformly blended to a workable consistency.
Induction time 70°F/21°C 15 minutes |
| 4. | Do not mix more material than can be used within the expected pot life, 41.2 hours at 70° F. |
| 5. | For optimum application, material should be from 50° to 90° F (10° to 32° C). |
| 6. | Use only PPG recommended thinners at 1 pint/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 passes with 50 percent overlap to avoid holidays, bare areas and pinholes. If required, cross spray at right angles. |
| 9. | When applying directly over inorganic zincs or zinc-rich primers, a mist coat/full coat technique may be required to minimize bubbling. This will depend on the age of the Dimetcote, surface roughness and conditions duringcuring. |
| 10. | Ventilate confined areas with 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 immediatelyafter use. |
