Common problems and solutions in the use of liquid silicone

When we use liquid silicone, I believe everyone has encountered different problems to some extent. After sorting and categorizing, the editor has identified the following points. While sorting out the problems with liquid silicone, the editor has also provided corresponding solutions for each problem. Let's take a look at the specific problems!

1. Bubbles appear on the surface of silicone gel
Possible reason: No vacuum defoaming treatment was performed.
Solution: Silicone is a viscous liquid that produces bubbles during mixing and stirring, which is a normal phenomenon. After stirring, vacuum defoaming should be performed.

2. Thickening phenomenon of liquid silicone
Possible reason: Silicone has a shelf life, and as time increases, the viscosity of silicone will thicken.
Solution: It is recommended to use it within the shelf life.

3. Incomplete solidification of liquid silicone
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 cures too quickly
Possible reasons: Excessive proportion of curing agent added, or high ambient temperature.
Solution: Excessive ratio of curing agent and high ambient temperature are the main reasons for accelerating the curing of silicone gel. It is possible to reduce the ratio of the curing agent and adjust it by controlling the ambient temperature.
The above are some problems and solutions that may be encountered when using liquid silicone, which need to be adjusted and handled according to specific situations.
