Silicone rubber for precast concrete mold
1. Discription of Silicone rubber for precast concrete mold
Silicone rubber for precast concrete mold is a kind of flowable liquid silicone, the quality has nothing to do with the color. It consists of two components. Part A is a flowable liquid silicone rubber, part B is the curing agent. Firstly, after your previous work of dealing with the original model, take some liquid silicone rubber , add 2%-3% curing agent of the amount of silicon, and mix them evenly. Then after vacuum-pumping the mixture, you can pour it into the mold frame. The silicone mold will cured in 2-4 hours.
And more curing agent is needed; contrarily, if molds requiring slower drying and demould, less curing agent is needed.
2.Application of Silicone rubber for precast concrete mold
Silicone rubber for precast concrete mold is primarily intended for mold making of gypsum, concrete, poly resin ,PU resin, unsaturated resin crafts, lighting and candles crafts , plastic toys , stationery gifts crafts industry, large statue, Buddha, relievo furniture, furniture decorative materials, statues Buddha, artifacts copied, building decoration materials, large-scale cement mold, artificial fossils Factory, European buildings, simulation landscapes, animals and plants sculpture, sandstone crafts and so on.
3.Features of Silicone rubber for precast concrete mold
1.Good resistance to deformation, high-temperature, acid-alkali and expansion
2.High reproduction times
3.High tensile strength ,tear strength and elongation.

5.Frequently asked question of Silicone rubber for precast concrete mold
Why does the silicone mold appear to be dry outside but wet inside?
Because molding silicone rubber is a kind of condensation silicone rubber, which get solidified after absorbing moisture from the air. In order to provide a significant shelf-life for the silicon rubber, we will dry out the water in the silicon rubber.
Solution: Add 0.05% water into the silicon rubber and Stir over a low speed briefly when you use it.
