1. Bubbles appear on the surface of silicone
Possible cause: No vacuum and 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 of liquid silicone
Possible reason: Silicone has a shelf life, and as time increases, the viscosity of the silicone will thicken.
Solution: It is recommended to use it within the shelf life.
3. Incomplete solidification of liquid silicone
Possible cause: The mixture of silica gel 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 curing agent ratio and high environmental temperature are the main reasons for accelerating the curing of silicone. It can be adjusted by reducing the curing agent ratio and controlling the environmental 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 circumstances.
