What is the relationship between the curing time of vulcanized silicone adhesive
27 Aug 2025
The curing time of silicone vulcanized adhesive at high temperatures is closely related to the temperature.
Generally speaking, as the temperature increases, molecular motion within the adhesive intensifies, accelerating the crosslinking reaction rate and thus shortening the curing time.
Therefore, using silicone vulcanized adhesive at high temperatures can significantly reduce the curing time and improve production efficiency.
However, excessively high temperatures can also cause the adhesive to cure too quickly, leading to internal stress concentrations and residual bubbles, which can affect the bonding effect.
Therefore, when selecting the curing temperature, it is important to consider factors such as the adhesive formulation, thickness, operating environment, and the desired curing strength.
Generally, manufacturers provide recommended curing temperature ranges and times, and users should select them based on their actual conditions.
In actual operation, the optimal curing time and temperature combination can be determined through experimentation.
Apply the adhesive to the materials to be bonded and then conduct curing tests at different temperatures. Observe and record indicators such as the curing time, post-curing appearance, and performance.
Through comparative analysis, curing conditions that meet performance requirements while ensuring production efficiency can be selected.
