| SPECIAL RECOMMENDATIONS |
|---|
| Special Recommendations | Recommended cure: 7 days at room temperature. · DC 93500 can be filled with silica for thixotropy and with silver powder for electrical conductance. In these cases, a high temperature cure is necessary (24 hours @ 80°C). · Where high adhesion is required, use a primer: DC 1200 (red) or DC 92023 (clear). · Sensitive to contamination, particularly when cured in thin layers. · Three commercial versions are available: DC 93500 (thixotropic), DC 93500 (high viscosity) and DC 93500 (low viscosity). |
| Lessons Learned | Lot reproducibility is excellent |
