Introduction of Silicon for Candle Mold Making
Silicon for Candle Mold Making is a two-component material, which consists of Part A base silicon and Part B CA30 curing agent; then the silicone base and curing agent can cure at room temperature by a condensation reaction. These materials can also be cast into the cured silicone mold: plaster, polyurethane, PU, GRC, cement, resin, polyester, wax etc.

Characteristics of Silicon for Candle Mold Making
1. Good flow ability and long working time
2. Low hardness, easy de-mold
3. High tear and tensile strength
4. Acid and alkali-resistance
5. Low linear shrinkage
Applications of Silicon for Mold Making
RTV-2 silicon can be applied in many objects mold making, since the RTV-2 silicon has good flow ability and medium hardness, and the silicon can cure at room temperature, thus it's a good material for duplication.
RTV-2 Silicon can be used for artificial stone mold making. For example, RTV2030, RTV2066 and RTV2088 silicon.
RTV-2 Silicon can be applied in candle and soap mold making, such as RTV215 and RTV218 silicon.
RTV-2 Silicon can be used for plaster mold making, such as RTV2025, RTV2028 and RTV2030 silicon.
RTV-2 Silicon can be applied in the field of shoe sole mold making, for example, RTV3010 and RTV3015 silicon.
RTV-2 Silicon rubber can be used for prototyping and electronic potting.
Silicon for Candle Mold Making is suited for middle size reproduction of candle mold, soap mold, small size concrete stones, artificial stones, plaster molding, figures, art objects, decoration molding, and the products with thin flower patterns.

Instructions for Making Candle Silicone Molds
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 of Silicon for Candle Mold Making
When the Silicon for Candle Mold Making is stored at or below 30 °C(85 °F) in the original unopened containers, RTV2 Silicon 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 silicon for some minutes, then the silicone can be use again, no influence for other performance.
