COMPARISONS OF SILICONE AND URETHANE SEALANT DURABILITIES

A study is reported which attempted to provide comparative data on the performance of silicone and urethane expansion joint sealants. A secondary objective was the evaluation of aging in a Q-Panel (QUV) accelerated weathering device in comparison to outdoor weathering. Details of the study are described and the results are discussed. It is noted that without either definite failure to survive the test procedure or loss of movement capacity below a reasonable safe level, it is difficult to make judgments based on the material property data alone. Visible change in integrity may be as good a predictor of long-term service performance as the mechanical property data. It is also noted that the manner in which aging takes palce can be as improtant as the magnitiude of the change. The four sealants studied are ranked, and conclusions drawn regarding their performance are presented.
