Common problems and solutions for using liquid silicone gel

When we use liquid silicone gel, I believe everyone has encountered different problems to varying degrees,

1. Bubbles appear on the surface of silicone rubber

Possible reason: No vacuum degassing treatment was performed.

Solution: Silicone is a viscous liquid, and it is normal for bubbles to form when mixed and stirred. After stirring, vacuum degassing should be performed.


2. Thickening phenomenon of liquid silicone rubber


Possible reason: Silicone has a shelf life, and as time goes on, the viscosity of silicone will thicken.


Solution: It is recommended to use within the shelf life.


3. Incomplete solidification of liquid silicone rubber


Possible reason: The mixture of silicone component A and component B was not stirred evenly.


Solution: When stirring, attention should be paid to scraping the container wall thoroughly.


4. Liquid silicone rubber solidifies too quickly


Possible reasons: Excessive proportion of curing agent added, or high ambient temperature.


Solution: Excessive curing agent ratio and high ambient temperature are the main reasons for accelerating the curing of silicone gel. It can be adjusted by reducing the curing agent ratio and controlling the ambient temperature.


The above are some problems and solutions that may be encountered when using liquid silicone gel, which need to be adjusted and handled according to specific situations.
