In ambient atmosphere, the crosslinking reactions are mostly hydrolysis and polycondensation reactions [37]; these are shown in Figure 5. Thereby, the ≡Si–NH–Si≡ group reacts with a water or an oxygen molecule under formation of silanol groups, which subsequently polymerize to polysiloxane via polycondensation.
