3M Dew Resistant Film 1180 Series Clear

Guaranteed to provide effective dew resistance for 7 years. The dew resistant properties also help protect the sign face against dirt and moisture, making it easy to clean.

The clear, high surface energy film promotes the coalescence of individual dew droplets. Dew cannot form on the sign face and cause refraction of light, leading to a loss of retro-reflection on the sign face.
