| Abstract: | This paper studies the performance variation of the structural silicone sealant before and after aging under different environmental conditions and mechanical stresses.It compares the decay rates of the bonding strength of the sealants,which are obtained from different producers,during aging.It also points out that there is decay rate variability of mechanical property among different structural silicone sealants during aging.It is more reasonable to evaluate the service life of silicone structural sealant by its decay rate of mechanical property during aging. |
