Pourable Condensation-Curing Silicona Mould Making RTV2 Silicone Liquid Rubber For Making Cement GRC Molds

Brief Introduction of silicone liquid rubber

RTV-2 silicone rubber is a two component material,and it consist of Part A base silicone and Part B curing agent.When the two parts mix together and pour or brush on a object,the silicone base and curing agent can cure to be a silicone mold at room temperature;and 24 hours later,the silicone mold can be released from the object,and then the silicone mold can be poured into the following material to copy: plaster,polyurethane, PU, GRC, cement, resin, polyester, wax etc...

Feature of silicone liquid rubber

Good characteristics of easy-operation
Light viscosity and good flowability
Low shrinkage

1. Make sure the surface of the original is clean and free of loose material.

2. Weight 100 Part A base and 2 parts of CA30 Curing Agent in a clean container.

3. Stir Part A base silicone before use thoroughly , as filler separation may occur upon prolonged storage.

4. Mix Part A and Part B evenly until the CA30 completely dispersed in the base.

5. Pour the mixed Part A base silicone and CA-30 curing agent as soon as possible onto the original

6. De-mold after 24 hours ,it is will improve the replicate times of silicone mold.

Note:It is strongly recommended that entrapped air be removed in a vacuum chamber, allowing the mix to completely expand and then collapse. After a further 1-2 mins under vacuum, the mix should be inspected and can be used if free of air bubbles. A volume increase of 3-5 times will occur on vacuum de-airing the mixture. So a suitably large container should be chosen.

Storage & Shelf life

When the silicone rubber is stored at or below 30 centi degree in the original unopened containers, Silicone Base and Curing agent have a usable life of 10 months from the date of production. After 10 months stockpiles use the Stir to mix the Part A silicone for some minutes, then the silicone can be use again, no influence for other performance.
