Abstract
AbstractExisting accelerated laboratory adhesion tests for silicone sealants are shown to lack the discrimination necessary to assess relative adhesive behavior. A novel test protocol is offered that enables improved discrimination by more precisely quantifying the adhesive strength of the sealant/substrate system. The method is based on the simultaneous application of both mechanical and environmental stress, in order to promote adhesive failure at loads below the cohesive strength of the bulk sealant.
