To quantify this impact, consider these factors:

1. The chemical reaction relies on moisture exposure to initiate and accelerate curing reactions.
2. In low humidity environments, the curing process can extend by several hours or even days beyond expected times.
3. This delay may also affect peel strength, potentially compromising the bond’s durability and sealing effectiveness.

In such environments, understanding and adjusting curing expectations are essential for ensuring silicone performs as intended. Monitoring environmental conditions and compensating for low humidity can mitigate adverse effects on cure times and peel strength.
