RTV silicone for gypsum decorations mold making
These materials have some extreme differences and some obvious similarities with other elastomers.
♥Usually measured on the Shore "A" hardness scale
♥Usually processed on very similar equipment, both for mixing and for fabricating
♥Silicones often have lower physical properties at room temperature than non-silicones
Non-Silicones often have lower physical properties at extreme temperatures than silicones
♥ Silicones are inherently good at resisting UV & Ozone - Non-Silicones typically have to be specifically formulated to offer improved resistance
♥Silicones exhibit poor abrasion resistance at room temperature but are hard to beat at 450° F
♥Silicone is usually available in all colours but black - special black pigments can be used but most times black is avoided as a silicone pigment
♥ Non-silicones are usually available in black

1. Application for RTV-2 silicone for mold making :
Liquid Silicone Rubber is primarily intended for poly resin crafts, PU crafts, PU resin crafts, gypsum crafts, unsaturated resin crafts, lighting and candles crafts, plastic toy, stationery gifts crafts industry, a large statue Buddha, relievo furniture, furniture decorative materials, statues Buddha, artifacts copied, building decoration materials, large-scale cement mold, artificial fossils Factory, Europe component factory, simulation landscapes, animals and plants sculpture, sandstone crafts and so on.
2. Instruction for RTV-2 silicone for mold making:
Add curing agent of 2%-3% at the room temperature, the silicone rubber is still operational within 30 minutes, and in 2-3 hours.
1. Adding curing agent 1%, the silicone rubber can still be operated within 2.5 hours and can be Demoulded after 6-8 hours.
2. Adding curing agent 2%, the silicone rubber can still be operated within 50 minutes to 1 hour and can Be demoulded after 2-3 hours.
3. Adding curing agent 3%, the silicone rubber can still be operated within 28 - 30 minutes and can bedemoulded after 1.5-2 hours.
4. Adding curing agent 4%, the silicone rubber can still be operated within 10 - 15 minutes and can be demoulded after 1 -1.5 hours.
3.Standand datasheet of RTV-2 silicone for mold making:
Model | Color | Mixing ratio (%) | Pot life (mins) | Demould time ( hrs) | Hardness ( A0 ) | Tensile-strength (kgf/cm2) | Tear-strength (kgf/cm) | Viscosity (cps) | Shrinkage rate (%) | Elongation (%) |
625# | white | 100 : 3 | 40 | 5-10 | 25 | ≥ 38 | ≥ 28 | 34000-36000 | ≤0.3% | 380% |
620# | white | 100 : 3 | 40 | 5-10 | 20 | ≥ 47 | ≥ 35 | 28000 | ≤0.3% | 430% |
4.Steps of RTV-2 silicone for mold making:
Step One: Take 100g of part A and add 2g of part B and mix the silicone rubber and curing agent evenly.
Notes: Moulding silicon rubber is a kind of flowing liquid and it contains two parts. Part A is a kind of white flowing liquid and part B is the curing agent.
Step Two: vacuum pumping
Without exception, this step takes less than 10 minutes.
Note: The time for vacuum-pumping should be less than 3—5 mins , otherwise, once the silicone rubber has cross-link reaction during vacuumizing, it will not be operated.
Step Three: Brushing cast & Perfusion Molding operation
