Attributes/comments: Atlas introduces an enhanced and fully digital control system for the Ci4000 xenon-arc Weather-Ometer giving operators more flexibility and control of their accelerated weathering
Data on transparent, compression molded flexible PVC [ILLUSTRATION FOR FIGURE 1 OMITTED] shows PR-25 to outperform Ciba's Tinuvin P benzotriazole, traditionally a workhorse for flexible PVC, after 3000 hr of accelerated weathering
Technical service: Outdoor (real time) weathering in 23 exposure sites around the world; outdoor accelerated weathering
(EMMAQUA, EMMAQUA+); instrumental color, gloss, visual evaluation, physical, optical and mechanical analysis
Customers across Europe now have a new option for reliable and cost-effective accelerated weathering
and corrosion contract testing from “the most trusted name in weathering.
In terms of testing and evaluation, the company considers exterior exposure testing still to be the "gold standard," and PPG continually correlates all of its accelerated weathering
testing to actual exterior exposures.
Product name: New Controller for QUV Accelerated Weathering
Instrumentation: QUV accelerated weathering
testers, MTG multi-test gravelometer, cyclic salt fog chamber
IRC products show compressive strength up to 5000 psi, tensile strength up to 2200 psi, negligible thermal creep at up to 200 F, no outgassing, and uv stability to 2000 hr of accelerated weathering
Acceptable weathering requires painted parts be tested under a variety of accelerated weathering
tests including Xenon Arc Wx, Carbon Arc Wx, and QUV, and up to five years of outdoor exposure in Arizona and Florida.
Testing services offered include physical and mechanical properties of materials, chemical and thermal analysis, environmental simulation and accelerated weathering
testing, metallurgical services, EMI/EMC testing, electrical and electronics testing, mechanical and fatigue testing, fuel systems and fuel component testing, vibration and shock testing, impact dynamics testing, full vehicle environmental testing and commercial calibration.
After 9000 hr of natural accelerated weathering
, [Delta]E was 5 versus 9.
