How can liquid silicone be vacuuming without a vacuum machine?

Before using the silicone rubber, the two components (A and B) need to be mixed fully and evenly. In the process, a small amount of bubbles will be generated. If the silicone is used directly without bubble discharging treatment, there will be small pores on the surface after the silicone rubber is cured and shaped. For most people, the quality requirements are relatively strict, they regard them as defective products if the silicone with bubbles inside. Therefore, generally speaking, manufacturers will prepare vacuum machines to assist in use; However, as a small number of individual users, it is not necessary to buy vacuum machines alone; How can we achieve the effect of bubble discharge without a vacuum machine?

1 after the two components of silicone AB are mixed, bubbles will be generated. At this time, it is also possible to use a hair dryer to transport cold air for bubble discharge and external treatment, or to use a toothpick or a needle to pierce large bubbles. Small bubbles will be eliminated slowly and automatically.

2. It can also reduce the use of agent B (curing agent), prolong the crosslinking time after mixing of AB components, and allow sufficient time for silicone rubber to automatically discharge air, so as to achieve the effect of true vacuuming.
