PVSTOP is designed to work effectively across a temperature range of 5°C – 60°C (41°F – 140°F).. In warmer temperatures, the coating dries faster, while in colder temperatures, it dries slower. However, the coating doesn’t need to be dry to effectively de-energize the solar PV system. It’s crucial to note that PVSTOP must never be allowed to freeze before use, as this will compromise its integrity, effectiveness and void the product warranty. For optimal performance, always store PVSTOP within the recommended temperature range.
