liquid silicone rtv2 for molding
Description of liquid silicone rtv2 for molding
HY Liquid Silicone for Moldmaking is a two-component material, and the RTV-2 silicone rubber includes Part A base silicone and Part B 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...
Features of liquid silicone rtv2 for molding
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 of liquid silicone rtv2 for molding
HY Liquid Silicone for Moldmaking 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. Etc.
Frequently asked questions of Silicon Rubber
Why does the silicon mould appear to be dry outside but wet inside?
Because molding silicon rubber is a kind of condensation silicon rubber, which get solidified after absorbing moisture from the air. In order to provide a significant shelf-life for the silicon rubber, we will dry out the water in the silicon rubber.
Solution: Add 0.05% water into the silicon rubber and Stir over a low speed briefly when you use
Instructions for liquid silicone rtv2 for molding
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 Curing Agent with ratio of 100:5 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 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 liquid silicone rtv2 for molding
When the Liquid Silicone for Moldmaking is stored at or below 30 °C(85 °F) in the original unopened containers, RTV2 Silicone Base and Curing agent have a usable life of 10 months from the date of production. After 10 months,please use a stockpiles to stir the Part A silicone for some minutes, then the silicone rubber can be use again, no influence for other performance.
