Briefly, for the wet exposure test, a weatherometer chamber was used.
This world-class, A2LA accredited and ISO 9001 certified lab and innovation and development hub features state-of-the-art analytical equipment such as DSC, FTIR, TGA, QUV/xenon-arc weatherometer, and an array of testing platforms for physical properties and color analysis.
The artificial weathering tests (alternated exposure to UV radiation, water spray, and condensation) were performed in a laboratory weatherometer (Q-Panel Lab Products, model QUV/spray).
With regard to weatherability, the 1K polysiloxane demonstrated a color change ([DELTA]E) of ~0.40 after 4000 h of accelerated weathering in a Xenon-Arc Weatherometer (WOM) chamber according to ASTM G155, (12) whereas the color change for qualified silicone alkyds and two qualified 2K polysiloxanes was significantly greater (Figure 5) The 1K polysiloxane also demonstrated a gloss loss of ~23% compared to that of 50% or greater for the qualified topcoats.
Weathering resistance of HBUA coatings was evaluated as per the method described in ASTM G-53 by exposing the resin coated aluminum panels (150 x 75 x 1 mm) to UV-radiation ([lambda] = 285-315 nm, UV-B bulbs) and high humidity condition in a QUV-accelerated weatherometer. A weathering cycle, comprising 2 h of condensation (at 45 [+ or -] 5[degrees]C) and 4 h of UV exposure (at 60 [+ or -] 5[degrees]C), was maintained during the study.

This data was generated using a Xenon arc weatherometer operated according to interior automotive test method SAE J2412.
Exposure chambers with an ultraviolet light (UV) component, such as QUV cabinets and the Atlas Weatherometer, simulate both daylight and rain cycles in an outdoor environment for realistic accelerated weathering of coatings.
The nylon fibers were exposed to UV using a Q-panel UV (QUV) weatherometer (QUV, Q-Lab, OH) with a UV wavelength of 340 nm as stated in ASTM G 154.
Northwire is pleased to offer another premier custom cable solution to our valued customers that meet four top tier approvals and 1,000 hour weatherometer compliance to ensure the longest product life,” says DePratter.
Xenon arc and carbon arc weatherometer test results show delta E values of less than 3.0 for all TPV sunroof seals in service today.
