Accelerated weathering is actually a very powerful tool for comparative purposes. Testing simultaneous multiple formula can quickly give vital information. Instead of waiting years to get the data from outdoor exposure or feedback from customers, accelerated weathering gives you the data you need in days or weeks. Weatherometer is a laboratory device that uses high-powered light sources & water to simulate long-term outside exposure. Ultraviolet (UV) light, a wavelength of light from the sun not visible to the human eye, can cause long-term damage to paints, plastics,fabrics and concrete finishes. Water, including rainwater and ocean saltwater, can attack finishes and degrade them. The Weatherometer can create ultraviolet, indoor, or other light frequencies to test products under controlled conditions and include water spray to add further environmental effects. Test materials are formed into panels that can be...
