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. |
