1. Description
Tin/Condensation cure mold making silicone rubber is a kind of liquid RTV (room temperature
vulcaniza-tion) silicone rubber with two parts, mix ratio with 100:2/2.5, part A is the silicone rubber
base, part B is the curing agent. It is the flexible mold making material with different hardness from 10
shore A to 40 shore A.

2. Features
☆ Exceptional fluidity and good operability, easy to demold
☆ Strong tear strength and tensile strength
☆ Excellent resistance to weather, temperature, acid and alkali
☆ Not oily, low shrinkage
☆ High temperature resistance,high duplication times and repeated use
☆ Suitable for both pouring molding and brushing molding


3. Applications
for concrete/stone/cement/brick/clay mold making
for plaster/gypsum/GRC/GRFC mold making
for resin/PU/bronze/crystal mold making
for casting/sculpture/figurines/statues/art mold making
for architecture/decor/furniture mold making
for polyurethane animals/Buddha mold making
for plaster line/cornice/roman column mold making
for wax/candle/soap mold making
for tyre mold making

Using instructions:
Step 1: prepare the original molds
Prepare an perfect mold modle and clean it totally(the release agent can be detergent, soapy water and Vaseline)before operation .Take 100g silicone material and 2~5g curing agent strictly and mix them evenly.
*Notes:Make sure the toys and operation tool cleaned up totally to avoid uncure problem .

Step 2: Vacuum pumping
Without exception, this step takes less than 10 minutes.(normally is 5munites) Otherwise, it will cause cross linking reaction, and no more further steps will be available.

Step 3: Pouring casting or Brushing operation
1. For simple pattern products we suggest use pouring operation way, which will be very easy to operate and demould. Pourable silicone require light viscosity which will be easy to flow smoothly and easy to de-air . (mold with fine and precision  patterns with low hardness.)
2.For delicate pattern products we suggest use brushing operation way.which can copy the pattern exactly .brushing way require high viscosity which won’t be easy to flow away and easy to brush(large size molds with high hardness)
3.The amount of the curing agent can be adjusted according to the actual requirements of the customer. If molds requiring fast drying and demould, more curing agent is needed; contrarily, if molds requiring slower drying and demould, less curing agent is needed.but we don’t suggest to add silicone oil avoid oil problem.

Step 4:Demoulding:
After 35 hours later, can demould the silicone mold, it's will be better for molf to demould after 24 hours.
Notes:The curing temperature and curing time can be adjustable according to the operation conditions.
