QUV Accelerated Weathering Testers

Two QUV Accelerated Weathering Testers from Q-Panel Lab Products reproduces the damage caused by sunlight, rain and dew.  The QUV tests materials by exposing them to alternating cycles of light and moisture at controlled, elevated temperatures.  The QUV simulates the effect of sunlight with fluorescent ultraviolet (UV) lamps.  It simulates dew and rain with condensing humidity and water sprays.  Exposure conditions can be varied to simulate various end-use environments.

In a few days or weeks, the QUV reproduces the damage that occurs over months or years outdours.  Types of damage include color change, gloss loss, chalking, cracking, hazing, embrittlement, and strength loss. QUV test data can help in the existing materials or the evaluation of changes in formulations.
