Objetivo
-To develop and utilise realistic accelerated weathering regimes.
-To design and manufacture devices for subjecting joint sealants to cyclic movement while undergoing accelerated or natural weathering.
- To develop sensitive techniques for analyzing degraded sealants.
-To develop a model to predict the life expectancies of sealants in three chosen climatic zones to within expected limits of +/- 3 years.
- To provide end users and designers with information on performance and life expectancy of sealants on which to base their product selection.
The main project objective was to establish accelerated weathering programs and test procedures to enable reliable predictions of sealant performance and suitability for a given climate. Although a definitive new methodology has not been fully achieved, in part due to the time scale of the project, a substantial step forward has been accomplished in the accelerated weathering of sealant materials. The project has highlighted the important effects of cyclic stressing, moisture, and temperature in the reliable prediction of long-term performance.
