New Weathering Test Method for Sealants and Preliminary Experimental Results

Source

A new sealant weathering test method expands on existing test methodologies. In ASTM C719, repeated movement cycles were shown to be important to reproduce some of the damage seen on real buildings. Weathering tests done previously demonstrate that water, sunlight (especially the UV portion), and heat are all important degradation factors that act on real buildings. Thus this new test combines water, heat, light, and movement acting on a sealant joint, fabricated to an ASTM C719 joint configuration, in artificial weathering machines. The joints are also subjected to identical movement in four different climates. Correlations of the damage done to various sealants in four varied U.S. climates and the artificial weathering machines are explored.
