Water is essential in such a process as well as is in need of the Sn titanic catalyst. Thus, hardening process is affected by moisture and the deep part remaining not in contact with moisture tends to be retarded in hardening. It remains stable while remaining not in contact with moisture, but once it was exposed to moisture, the part of Si-X is replaced with Si-OH, resulting in condensation reaction. In the wake of a gradual reaction, a crosslinking occurs, which leads to transforming into the elastic body
