Q-Lab is a world leader in weathering, light stability, and corrosion testers and standard test substrates. We offer outdoor exposure testing at our benchmark facilities in Florida and Arizona. Contract test services, including accelerated laboratory...

The QCT condensation tester simulates the damaging effects of outdoor moisture attack. In a few days or weeks, the QCT tester can reproduce the damage due to moisture that occurs over months or years outdoors.The QCT tester is fast, easy to use and a...

Condensation is an excellent way to simulate the moisture attack that materials experience outdoors. High-humidity condensing environments can be generated in QCT, QUV, Q-SUN and Q-FOG testers. However, not all condensation testing is the same. There...

There are quite a number of laboratory methods for accelerated simulation of the damage caused by rain and dew on metals and organics. However, the old fashioned methods of water immersion, high humidity, fog, or salt spray are not entirely satisfact...

The QCT® condensation tester is based on the Cleveland Condensing Humidity Cabinet, originally designed by the Cleveland Society for Paint Technology. The QCT tester simulates rain and dew by condensing liquid water directly onto the test specimen. T...

The VIRTUAL STRIPCHART™ data logging software collects data from Q-Lab testers and stores it on a personal computer. It records and displays data on critical test parameters such as temperature, irradiance, and relative humidity. The VIRTUAL STRIPCHA...

Weathering causes millions of dollars of product damage every year. Damage includes color change, gloss loss, strength loss, cracking, peeling, chalking and oxidation. The main causes of weathering are sunlight (especially UV), high temperatures, and...

Understanding how to best protect a plastic part from the effects of weathering needs to include an analysis of several important factors. It should take account of the polymer type, colour and additives. An estimation of what the actual exposure wil...

The basic stresses in weathering are known and quantified. The time a material is stressed and the temperature during UV and water stresses are the primary variables in natural weathering. Reproducing them exactly in the laboratory can provide accele...

Outdoor exposure racks and accelerated chambers are the two main methods for testing materials for weathering durability. In the fast paced current world, time constraints have determined that outdoor weathering exposures take too long to provide the...
