How to use
You can match according to the size, complexity of structure, and use of the mold seed. After fully mixing and stirring, pour it into the mold seed, and then vacuum together;
After vacuuming, pour all the remaining liquid silicon into the mold;
After the silicone liquid rubber is completely cured (3-4 hours), remove the cardboard and the silicone mold. Then trim the excess silicone with scissors;
Take out the mold, and trim the edges;
It can be put into production after 24 hours, and keep the silicone mold in a ventilated, cool and dry place;
Store and Caution
It can be stored unopened for 12 months at a room temperature of 25°C.
Recommended that the finished liquid silicone mold be put into production 24 hours later.
It belongs to condensation type mold silicone liquid and cannot be mixed with addition type silicone liquid.
