Application may be made at temperatures as low as 10F (-12C) to a clean and dry surface. The sheeting will remain serviceable for many years when properly applied to a suitable substrate and used in typical indoor or outdoor environments. The sheeting maintains approximately 90% of its dry brightness with water falling on the surface (Rainfall Test Method of Federal Highway Administration Specification, FP-74, Section 718.01 6 ). Use in high temperature environments (above 200F 93C ) for an extended period of time could permanently reduce retroreflective efficiency. Repeated freeze-thaw cycles may cause subtle but visible cracking of the reflective surface, which should not significantly affect performance. Extreme cracking will reduce the optical performance of the sheeting. Storage Conditions Store in a cool, dry area, preferably at 70-75F (20-24C) and 30-50% relative humidity, and horizontally in shipping carton. Avoid pressure from stacking. Shelf Life Product should be applied within one year after purchase.
