Condensation Cure Silicone Liquid Rubber For Making Bark Planter Concrete Mold
Product Description
Silicone liquid rubber is is generally named as two-part room temperature sulfurated 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.

Typical Properties of RTV-2 silicone liquid rubber
Operation Instructions of Silicone Liquid Rubber
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.
Package of RTV-2 Silicone Liquid Rubber
Part A base silicone: 25kg/drum or 200kg/drum
Part B CA30 Curing Agent: 800g/bottle, 1kg/bottle
Storage & Shelf life
When the silicone rubber is stored at or below 25℃ (77℉) with the original unopened containers, Silicone Base and Curing agent have a usable life of 12 months from the date of production. After 12 months stock, please use the Stir machine to mix the Part A silicone for some minutes, then the silicone can be used again, no influence for other performance.
