What is a concrete mold with silicone rubber?
The application of silicone rubber in the concrete mold
Silicone rubber is mainly used for concrete products, concrete veneers, concrete pavements, concrete fountains, artificial stones, artificial stones and other concrete products.

Silicon rubber for concrete mold
Silicone rubber for concrete mold is white fluid, and its hardness is 22-50A degrees after curing.
(1) high tensile strength
(2) high repetition times
(3) low linear shrinkage
(4) high temperature resistance
(5) low shrinkage and non deformation
(6) acid alkali and expansion

Operation rules of silicon rubber concrete mold
Step one: take 100gof A and B parts and mix silicone rubber and curing agent evenly.

Second step: vacuuming
Without exception, this step will take less than 10 minutes.
Note: the vacuum time should be less than 3~5 minutes. Otherwise, the crosslinking reaction of silicone rubber in vacuum will not operate.

Step three: pour the vacuum silicone mixture into the frame with the original concrete mold.

Storage period of silicon rubber concrete mold
Store in a cool dry place for 25 months at room temperature for 10~12 months.
