Product Description

Product Description
 
RTV-2 is a two-component Room-Temperature-Vulcanizing (RTV-2) silicone rubber. Depending on its curing mechanism, two types of RTV-2 are available: "condensation" cure type and "addition" cure type. RTV-2 silicone rubber is a two-component material, and the RTV-2 silicone rubber includes Part A base silicone and Part B CA30 curing agent. The Part A base silicone and Part B curing agent can cure at room temperature by a condensation reaction. These materials can be cast into the cured silicone mold: plaster, polyurethane, PU, GRC, cement, resin, polyester, wax etc...

Product Features
 
1. Good flow ability and long working time
2. Medium hardness
3. High tear and tensile strength
4. Easy de-mould from complex replica parts
5. Acid and alkali-resistance
6. Low linear shrinkage
 
Applications
  
RTV-2 silicone rubber can be applied in many objects mold making, since the RTV-2 silicone has good flow ability and medium hardness, and the silicone can cure at room temperature, thus it's a good material for duplication.
RTV-2 Silicone Rubber can be used for artificial stone mold making. For example MCSIL-2066 and MCSIL-2088 silicone.
RTV-2 silicone rubber can be applied in candle and soap mold making, such as MCSIL-215 and MCSIL-218 silicone.
RTV-2 silicone rubber can be used for plaster mold making, such as MCSIL-2025, MCSIL-H25 and MCSIL-2030 silicone.
RTV-2 silicone rubber can be applied in the field of shoe sole moldmaking, for example, MCSIL-S20 and MCSIL-S25 silicone.
RTV-2 silicone rubber can be used for prototyping and electronic potting.
RTV-2 Silicone rubber is suited for reproduction of cement molding, concrete stones, artificial stones, plaster molding, figures, art objects, decoration molding, GRC products, gypsum products, resin products, PU molds.
 
Using Instruction
 
1. Preparing
The surface of the original objects should be clean and free of loose material. If your products have thin flower patterns, and especially have porous substrates, please use a suitable mold release agent such as soap water, detergent, Vaseline or petroleum jelly.
2. Mixing
Please weigh Part A silicone base and part B CA30 Curing Agent with ratio of 100:2 into a clean container. Stir Part A base silicone thoroughly before use, then Mix Part A and Part B evenly until the curing agent completely dispersed in the silicone base. Manual or mechanical mixture can be used, but do not last much time or allow the temperature to exceed 35°C (95°F).it's suitable to mix small quantities to ensure thorough mixture of silicone base and curing agent.
Note: It is strongly recommended that entrapped air be removed in a vacuum chamber, allowing the mixture to completely expand and then collapse. After a further 1 to 2 minutes under vacuum, the mixture 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.
3. Pouring and curing
Pour the mixed Part A base silicone and CA-30 curing agent as soon as possible onto the original object, 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.

Storage & Shelf life
 
When the RTV-2 silicone rubber is stored at or below 30 °C(85 °F) in the original unopened containers, RTV2 Silicone Base and CA30 Curing agent have a usable life of 12 months from the date of production. After 12 months,please use a stirring mill to stir the Part A silicone for some minutes, then the silicone can be use again, no influence for other performance.
