ADDITIONAL INFORMATION / WEATHER TESTING
Weather Testing
Gemini is committed to the long term sustainability of our letters in all environments, and thoroughly tests all materials and coatings before adding any new products to our catalog. The most common failures of any sign product usually involve either prolonged UV exposure or reaction to envi- ronmental moisture or chemicals. We have established standards similar to those of the automotive industry for all our exterior grade materials and coatings. You can be assured that any Gemini product you install has been exhaustively tested for durability in all environments.
UV Testing
Gemini utilizes the Xenon Weatherometer to simulate prolonged UV exposure. One reason all Gemini products look as good today as they did 30 years ago is that they are made of pigmen- tation that can survive in test environments like you see in this image. This equipment utilizes a high watt Xenon Arc bulb that has the destructive capability of direct sunlight, in addition to cycles of humidity and darkness to represent the overall environ- ment of one year in just 2,350 hours. Gemini follows the J1960 automotive test standard that employs the cyclical humidity and temperature features of this machine.
Corrosion Testing
Gemini utilizes the Advanced Cyclic Corrosion Exposure System on our materials. This rigor- ous process includes salt fog, moisture and heat cycles to simulate long-term environmen- tal exposure in the harshest climates. After 1000 hours in this chamber, only the most chemical resistant products come out looking presentable. All Gemini paints and metals have passed these tests.
