Natural exposure testing is an essential part of any weathering and light stability test program. Q-Lab Weathering Research Service has outdoor exposure sites at internationally recognized benchmark locations in Florida and Arizona.
Q-Lab Florida is the southernmost test site in the USA. It has a subtropical climate with lots of sunlight, high temperatures and abundant moisture.
Moisture sensitive products like coatings and building materials, and some plastics are particularly affected. Florida is also an excellent site for testing mildew resistance.
Q-Lab Arizona Weathering Introduction
Natural exposure testing is an essential part of any weathering and light stability test program.
Q-Lab Arizona has an arid desert climate with more sunlight and higher temperatures than Florida. Typically, specimens in Arizona receive about 20% more sunlight than Florida.
Q-Trac Natural Sunlight Concentrator
The Q-Trac uses a series of 10 mirrors (a fresnel concentrator) to reflect and concentrate direct, full spectrum, natural sunlight onto test specimens. Q-Trac maximizes the amount of UV sunlight weathering test specimens receive. Depending on the test starting time, you can get the equivalent of 3 years of Florida UV exposure in just 6 months. Degradation rates are material specific.
