The Effect of Movement During Cure of a Silicone Sealant

Abstract
Movement of the building joint sealant during cure is thought to affect the fully cured mechanical properties. To examine this potential effect, a one-part silicone sealant was cured from 10 h to 168 h after sample creation before the onset of movement cycles. These cure times fall between the proposed RILEM TC-139 technical recommendation of 5 min and the ASTM C719 durability standard of 21 d. Apparently, enough cross-linking occurred prior to testing such that neither the overall movement history of the sample nor the deformation step shapes affected subsequent curing or mechanical properties of the sealant. A critical parameter for sealant performance appears to be the extent of cure at the onset of movement and not the extent of movement or step shape contrary to several literature references.Citation
