Amercoat 235 Mix Ratio
Amercoat One coating has the same chemical and corrosion resistance as traditional two-component epoxy coatings, and it can be used as an intermediate coating over inorganic and organic zinc-rich primers, or as a direct-to-metal (DTM) primer in multilayer coatings systems. It is well-suited to a variety of chemical, petrochemical. Material is supplied in two containers. Always mix whole units. The zinc metal is ready-mixed in Part A. Stir thoroughly with a slow speed mixer while slowly adding Part B. Continue to mix at slow speeds to a homogeneous condition. At temperatures of 60°F (16°C) or above, allow a 15 minute induction time before using.

| Application Procedure | |
| 1. | Flush all equipment with thinner or Amercoat 12 before use. Stir resin using an explosion-proof power mixer to disperse into a homogeneous mixture. |
| 2. | Add cure to resin.Mix thoroughly until uniformly blended to aworkable consistency.Induction time 70°F/21°C 15 Minutes |
| 3. | Do not mix more material than can be used within the expected pot life, 1.5 hours at 70°F.Higher material temperatures will shorten the pot life considerably. |
| 4. | For optimum application,material should be between 50° to 90°F (10° to 32°C). |
| 5. | Use only T-10 thinner at 10% by volume,maximum. |
| 6. | Below50°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 awet 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, amist coat/full coat technique may be required to minimize bubbling. This will depend on the age of the primer, surface roughness and conditions during curing. |
| 10. | Ventilate confined areas with clean air during application, 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. |
