Water resistance test of DMT in different concentrations
| Time DMT | 1 day | 3 days | 5 days | 10 days | 15 days |
|---|---|---|---|---|---|
| 0.5% | 78 | 76 | 76 | 74 | 74 |
| 0.6% | 80 | 80 | 78 | 78 | 78 |
| 0.7% | 86 | 86 | 84 | 84 | 84 |
| 0.8% | 86 | 86 | 86 | 84 | 84 |
Detection of hardness in water with different concentrations of DMT during 15 days. With an increase of DMT concentration, the higher hardness of the resin, the better the water resistance.
