Detailed
1.Applications of concrete stamps mold making silicone rubber :
Addition cure RTV2 Silicone for mold making is primarily intended for food grade products moldmaking, such as baby nipples, chocolates molds, cake molds, ect.
It can also be used for artificial stone mold making, concrete stamps mouldings,concrete ornaments mouldings
2. Features of concrete stamps mold making silicone rubber :
Platinum cured RTV2 Silicone is a kind elastic silicon rubber mold which features with resistance to deformation, high-temperature, acid-alkali and expansion as well as high reproduction times, good tensile strength, tear strength and elongation.

3.FAQ of making molds from poly-addition curing silicone rubber
What should we do when the air bubbles appeared in the process of mold making ?
To handle this situation depends on different cases. Under the condition of an available vacuum pumping machine, mix the silicon rubber and curing agent evenly and then take it to vacuum chamber to deair. If without a vacuum pumping machine, reduce the amount of the curing agent properly. For example, change the mixing ratio of the silicon rubber and the curing agent from former 4% to 1%-2%. In this way, the pre-crosslinking time of silicon rubber will slow down, so the air in the mold will be eliminated gradually to reduce the air bubbles.
