Results and Discussion

A variety of silicone sealants with different physical properties and chemistries were tested and are described in Table 1. Results reported are based upon ASTM Cl 135 testing with respect to maximum stress, maximum strain, and the secant modulus at a given strain. Standard deviations are reported, and each data point is the average of a minimum of three specimens. Sealants are listed in order of the manufacturers’ stated movement capability.
