Abstract

Three room-temperature fluid-applied silicone membranes intended for application in building envelopes were studied in this work. The membranes were subjected to accelerated UV and moisture aging for 5000 h to evaluate their resistance to long-term aging. The properties of the membranes were studied to understand the degradation mechanisms that might occur during accelerated aging. The weight loss, wetting propensity, cracking and oxidation resistance, and storage modulus were measured at different intervals during 5000 h of aging. Based on the material characterization results, the silicone membranes proved to be resilient under aggressive accelerated UV radiation and moisture aging, conditions that can be expected as a result of climate change.
