A good adhesion value, similar to that of the monosilanes, is also obtained for the specimen pretreated with 25% BTSE bis-silane, which does not have an organofunctional group to bond with the paint.
However, the type of failure obtained in this case with 25% BTSE, and with the other tested bis-silane, 25% BAS, was cohesive but with different points of adhesive failure, as can be seen in Fig.
The coatings containing bis-sulfur and BTSE silane fared best, reducing water uptake by 78% and 77%, respectively.
