Instructions of RTV-2 Silicon Rubber For Stone Molding
Correct mixing ratio
RTV-2 Silicon Rubber Component A is silicone rubber, and component B is curing agent or vulcanizing agent. Usually the mixing ratio will be 2-3%, e.g. to 100g silicone rubber should be added 2g catalyst and then mix them thoroughly. (Note: the weight of the silicone and catalyst should be weighed correctly).
Pouring the mixture and curing
Pour the misxed Part A base silicone and CA-30 curing agent as soon as possible onto the original,avoiding air entrapment.The catalyzed material will cure to a flexible rubber within 6 hours(or faster by different mixing ratio or room temperature),we advice you de-mold after 24 hours ,it is will improve the replicate times of silicone mold.
