Brushing Liquid RTV2 Silicone Rubber for Sculpture molds
RTV2 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...

APPLICATION
Brushable Silicon Rubber for Casting Mold (RTV-2) is primarily intended for poly resin crafts, PU crafts, PU resin crafts, gypsum crafts, unsaturated resin crafts, lighting and candles crafts, plastic toy, stationery gifts crafts industry, a large statue Buddha, relievo furniture, furniture decorative materials, statues Buddha, artifacts copied, building decoration materials, large-scale cement mold, artificial fossils Factory, Europe component factory, simulation landscapes, animals and plants sculpture, sandstone crafts and so on.
Note:
Silicone MCSIL series is an industrial product and must not be used in food contact and dental human skin molding applications.
PROCEDURES
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.
PACKING:
Part A :20kg/drum, 25kg/drum or 200kg/drum of silicone rubber
Part B :0.8kg/bottle, 1kg/bottle of silicone rubber
STORAGE:
When stored at or below 30 C (85F) in the original unopened containers, silicone base and CA30 Curing agent have a usable life of 12 months from the date of production. After 12 months stock, please use the Stir to mixing the Part A silicone for some mins, then the silicone can be use again, no influence for other performances.
