RTV-2 Silicone Rubber for Candle/Soap Moldmaking

详情

Description
 
RTV*2 silicone rubber is a two-component material, which consists of Part A base silicone and Part B CA*0 curing agent; then the silicone base and curing agent can cure at room temperature by a condensation reaction. These silicone rubber materials can be cast into the cured silicone mold: plaster, polyurethane, PU, GRC, cement, resin, polyester, wax etc.
 
Specifications
 
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
 
MCSIL***5/**8 silicone rubber 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.

Instruction for making RTV*2 silicone rubber mold

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 CA*0 Curing Agent with ratio of **0:2 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 *5℃ (*5℉).its 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 **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**0 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 *4 hours, it is will improve the replicate times of silicone mold.

Storage

When the silicone rubber is stored at or below *0℃ (*5℉) in the original unopened containers, RTV2 Silicone Base and CA*0 Curing agent have a usable life of *2 months from the date of production. After *2 months, please use a stirring mill to stir the Part A silicone for some minutes, then the silicone can be use again, without any influence to the characteristics.

Packing

Part A base silicone: *0kg/drum, *5kg/drum or **0kg/drum

Part B CA*0 Curing Agent: 0.*5kg/bottle,1kg/bottle and *0kg/bottle
