Silicon rubber for concrete molds operation instructions

Step One:Take **0g of part A and add 2g of part B and mix the silicone rubber and curing agent evenly.

Step Two:vacuum pumping

Without exception, this step takes less than *0 minutes.

Note: The time for vacuum-pumping should be less than 3—5 minutes ,otherwise, once the silicone rubber has cross-link reaction during vacuum pumping process, it will not be operated.

Step Three:Pouring the vacuumed silicone mixture into the frame with original concrete mold .

Shelf life for silicon rubber concrete molds

*0~*2months, when stored in a dry & cool place under the room temperature *5.
