When applied and fired correctly the range will meet the chemical resistance levels described above. This level of resistance, however, does not imply or guarantee any specific levels of resistance to atmospheric exposure or product lifespan.
We do not recommended that these glass enamels should be used in environments where they will be directly subjected to exposure to water and weather for extended periods. |
