Practical methods for increasing the flowability of liquid silicone

Hits: 266 img

Generally speaking, it's okay to keep liquid silicone for six months and a year. If it exceeds one year, the viscosity of silicone will thicken with time, and expired liquid silicone will solidify into a ball like the following picture, with almost no fluidity, which makes us very difficult.

Expired liquid silicone has very poor flowability and almost clumps, which can cause difficulty in mixing AB adhesive and uneven filling. If a large amount of silicone oil is added, it will cause a decrease in tear resistance and toughness after curing. How can we increase the flowability of liquid silicone without affecting its performance?

There is something called an expansion bolt on the market, and you can buy one with a suitable length based on the amount of silicone you have.
After buying it back, we will use pliers to break the front opening of the expansion bolt jacket into a cross shape, then tighten the nut, tighten it, and a simple mixing head will be ready.

Next, clamp the stirring head onto the electric drill and start stirring frantically. After stirring, the silicone gel regains its fluidity once again.
The liquid silicone that has just been stirred may generate a bit of heat due to friction and molecular motion, and there are many bubbles. It is not wise to use it immediately. Firstly, it is easy to foam, and secondly, it is easy to foam because the heat itself accelerates the reaction speed. Let it sit for a while and let it cool before use.
