Storage and Handling
Avoid extremes of temperature. Freezing may cause the coating structure to degrade locally, especially areas where the coating is in tension or compression – at bends and edges, and immediately adjacent to seam welds. Recommended storage temperature 40°F – 95°F. Shelf life at this temperature: in excess of 1 year.
Avoid prolonged contact with solvents and chemicals.
