Sunlight and moisture cause millions of dollars of material damage every year. The QUV Accelerated Weathering Tester reproduces the damage cause by sunlight, rain and dew.
The QUV test materials by exposing them to alternating cycles at light and moisture at controlled, elevated temparatures. The QUV simulates rain and dew with condensing humidity or water spray.
In a few days or weeks, the QUV can reproduces the damage occurs over months or years outdoors. Types of damage include fading, color change, gloss loss, chalking, cracking, crazing, hazing, blishtering. embrittlement, strength loss and oxidation. QUV test data can help in the selection of new materials, the improvement of existing materials or the evaluation of how changes in formulations affect product durability. The QUV gives excellent, relative prediction of how materials will fare when exposed outdoors.
