How to Discharge the Bubbles Produced by Mixing Liquid Silicone

Many people find a problem when dealing with silicone mold making liquid rubber products, which is that there are many silicone bubbles that cannot be completely discharged, resulting in the product not being aesthetically pleasing and unable to achieve the expected effect, causing huge losses.
Below, HANAST silicone rtv2 will teach you how to reduce the bubbles generated after stirring liquid silicone. Let's learn more together.
1、If it is a condensed silicone rubber mold liquid product, less curing agent can be added and the operation time can be extended to achieve the effect of natural foaming.
2、When the amount of curing agent added is the same, it can reduce the temperature of the operating space, thereby extending the curing time and making it easier to remove bubbles.
3、During the process of stirring liquid silicone products, please try to stir in the same direction as much as possible to reduce the number of bubbles.
4. Require manufacturers to reduce the viscosity of silicone during the production process, ensure good flowability, and make bubble emission easier. However, if the viscosity is too low, adding more silicone oil will also deteriorate the performance of the product.

A more practical method is to use a silicone vacuum machine. Regardless of the viscosity of the liquid silicone product, it can still be easily drained of all bubbles through a vacuum machine.

In summary, this is a method for reducing the bubbles generated by liquid silicone products after stirring using liquid silicone molds. I hope the above methods are helpful to you.
