Cyclic corrosion testing provides the best possible laboratory simulation of natural atmospheric corrosion. Research indicates that test results are similar to outdoors in resulting structure, morphology, and relative corrosion rates. Q-FOG cyclic co...

The Q-SUN Xe-3 xenon arc chamber reproduces the damage caused by full-spectrum sunlight and rain. In a few days or weeks, the Q-SUN tester can reproduce the damage that occurs over months or years outdoors. The Q-SUN Xe-3 tester is a full-featured li...

The Q-SUN Xe-2 rotating rack xenon arc test chamber reproduces the damage caused by full-spectrum sunlight and rain. In a few days or weeks, the Q-SUN Xe-2 tester can reproduce the damage that occurs over months or years outdoors. The Xe-2 tester is ...

The Q-SUN Xe-1 xenon arc chamber reproduces the damage caused by full-spectrum sunlight and rain. In a few days or weeks, the Q-SUN tester can reproduce the damage that occurs over months or years outdoors. The Q-SUN Xe-1 tester is a tabletop lightfa...

The QUV accelerated weathering tester reproduces the damage caused by sunlight, rain and dew. In a few days or weeks, the QUV UV tester can reproduce the damage that occurs over months or years outdoors. To simulate outdoor weathering, the QUV accele...

Humidity is a general term that describes the amount of water vapor in the air. Humidity is a critical element of the outdoor environment and contributes to the material degradation in both weathering and corrosion.Humidity can be expressed as either...

Q-Lab's Sean Fowler is one of the organizers for the upcoming Automotive Corrosion Symposium, presented by the Southwest Research Institute (SwRI) and held in Detroit, MI on 31 Mar and 01 Apr. This exciting event brings together industry experts from...

Background:  For a test in QUV we can choose between two conditions that give the same amount of total energy: Test A: Irradiance 0.65W/m2 for a time of 3000h.Test B: Irradiance 0.83W/m2 for 2500h.The testing samples are films, with a thick...

Q-Lab is Number 1 WorldwideQ-Lab has been producing standard test substrates since 1956. Today, we produce more paint test panels - by far -than anyone in the world. Q-PANEL steel and aluminum test substrates have long been recognized as the world st...

What Is Weathering?Weathering and LightstabilityWeathering refers to changes in material properties that result from exposure to the radiant energy present in sunlight, in combination with heat (including temperature cycling), and water in its variou...
