Stability of a commercially available single‐package silicone sealant has been investigated under different water immersion temperatures. The study involved water sorption, weight loss, thermal stability, and strength reduction. It is believed that the deterioration of silicone sealant was due to the combined effects of leaching, water swelling, and hydrolysis. Water uptake of about 2% was crucial for its hydrolytic degradation, especially at higher temperatures.
