100:2 China Manufacturer Concrete Planter Molds Mold Making RTV2
Silicone Rubber
Description of concrete planter Mold Making RTV2 Silicone rubber:
concrete planter Mold Making RTV2 Silicone is generally named as
two-part room temperature cure silicone rubber, which features an
exceptional fluidity and good operability. When mixed with 2%
curing agent, they can still be operated within 30 minutes, but
will be formed after 4-6 hours. With resistance to deformation,
high temperature, acid and alkali, and expansion.

Operation instructions of concrete planter Mold Making RTV2
Silicone:
Correct mixing ratio
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.
