Application Procedure

Amercoat 450H is packaged in two components in the proper

proportions which must be mixed together before use:

1. Flush equipment with thinner or Amercoat 12 before use.

2. Stir each component thoroughly, then add cure to resin and mix until uniformly blended to aworkable consistency. Do not mix more material than will be used within 4 hours at 65-80°F (18-27°C). Pot life is shortened by higher temperatures.
See pot life data.

3. Thin only if necessary forworkability.

4. When applying by conventional spray, use adequate air pressure and volume to ensure proper atomization.

5. Apply a wet coat in even parallel passes, overlap 50 percent to avoid holidays, bare areas and pinholes. If required, cross spray at right angles.

6. Application of 3mils (75microns)wet film thickness will normally provide 2mils (50microns) dry film.

7. Clean all equipment with thinner or Amercoat 12 immediately after use.

8. Keep containers tightly closed since repeated exposure to moisture will cause gelation. Moisture contaminated material is also subject to gassing on storage. Handle bulged containerswith caution; lids may eject forcibly.
