Below provided with a rheological measurement plot, the material involved in the measurement is silicone with condensation cured properties, the Blue curve refer to the original curing properties at 180oC for 8 hours, Red curve refer to the silicone that already soaked in water for 2 hours and it seems the curing rate is increased (storage modulus, G' increase as well), however the Green curve refer to the silicone that already soaked in water for 2 hours and further air dry to continue stage at room temperature for 168 hours, it seems that further staging can reduce the curing rate (storage modulus is decreased). Can you please help to figure out the reason and chemistry happened behind? Thanks.
