Abstract

Selecting a polymeric material for an application exposed to outdoor weathering is a challenging task. The proper selection requires knowledge of the behavior of the material, which is a complex mixture involving the integration of rheology, reliability based methodology, analytical chemistry, mechanical engineering, statistics, standards development, and economics. The research discussed here involves a precisely controlled temperature, humidity, Ultra-Violet radiation, and applied strain device to generate controlled exposure and characterization of the changes due to exposure in model elastomers and coatings. The focus of this paper will be on the effect of applied strain on the time dependant modulus change of these sealants.
