Resistance Rating Definitions
| Rating | Description |
|---|---|
| Excellent | Epoxy exhibits no significant degradation; suitable for continuous exposure |
| Good | Minor effects possible; suitable for most applications with monitoring |
| Fair | Noticeable degradation may occur; limited exposure recommended |
| Not Recommended | Significant degradation expected; avoid contact with epoxy surfaces |
Note: Temperature ratings indicate maximum recommended service temperature. Many chemicals that show "Excellent" resistance at room temperature (71°F / 22°C) may cause degradation at elevated temperatures. Always confirm compatibility with your specific epoxy formulation and manufacturer specifications.
