Product Description

Description of Fibrous plaster ornaments molding liquid RTV silicone:

Mold making RTV silicone rubber, Liquid Silicone Rubber, RTV 2 Silicone Rubber is general called two-component room temperature vulcanization silicone rubber with excellent fluidity and good operational performance. Add curing agent of 2% at the room temperature, the silicone rubber is still operational within 30 minutes, and in 4-6 hours, an elastic silicon mold will be obtained with resistance to deformation, high-temperature, acid and alkali and expansion.


Features of Fibrous plaster ornaments molding liquid RTV silicone:
Outstanding release properties
High Flowabilty and long woring time
Medium Hardness
High tear resistance
High elasticity for easy removal of complex replica parts

Applications of Fibrous plaster ornaments molding liquid RTV silicone:
A: Cultural relic duplication, architectural decoration, statues
B: Polyester Resin crafts
C: Lighting ornaments, soap, candles molding
D: Plaster, Gypsum, Cement, Concrete decorations
F: Model design, product exploitation, etc.

How to make the silicone 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 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 the mixture 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 Fibrous plaster ornaments molding liquid RTV silicone:

When the silicone rubber is stored at or below 30 centi degree in the original unopened containers, RTV2 Silicone Base and CA30 Curing agent have a usable life of 10 months from the date of production. After 10 months stockpiles use the Stir to mix the Part A silicone for some minutes, then the silicone can be use again, no influence for other performance.
