AbstractFourier transform infrared photoacoustic (PASFTIR) spectroscopy and thermogravimetry (TG) havebeen used to study the effects of exposure of silicone sealants to water in the presence and absence ofUV-radiation. The silicone sealants were found to be fairly resistant to the two types of weathering conditions for the duration of the exposure (8000 hours). Only a small increase in the hydroxyl absorption band was observed by PAS-FTIR. No substantial changes in weight loss were observed using thermogravimetry.
