Heat Resistant Silicon Elastomer Liquid Silicone for Polyurethane PU epoxy resin form
Description
Silicon rubber is a kind of elastomer, somebody also call it silicone elastomer. We only produce and provide rtv2 silicone rubber, it's liquid silicone which will vulcanize in both room temperature or heated temperature with good self-leveling ability.
Application and Advantages
Mold making silicone rubber for reproducing and replicating art crafts, furniture, prototyping, architectural elements, garden ornaments, shoe, tire, soap, candle, jewelry, vacuum bag and so on, since molding silicone is suitable for casting resin, PU, PVC, polyester, gypsum, plaster, concrete, cement, stone, GRC, wax, jewelry and so on.

Notes: Above data are only reference values, actual data is floating and adjustable.
Advantages:
1) Flexible and low viscosity which will copy finest details and patterns from exquisite products.
2) Durable with good strength, top quality to guarantee molding times
3) Easily demolding
4) Not oily, no bubbles
5) Can resist high temperature 200ºC - 350ºC, and low temperature -65ºC
6) Low shrinkage less than 0.2%, platinum cure type is less than 0.1%
7) Aging resistance, acid and alkali resistance
8) Platinum cure silicone is food grade certified, nontoxic, odorless
Operation instructions
- Mix part A and pars B evenly with 100:3 mixing ratio.
Notes: 1) Weigh the two parts exactly by electronic weight. For example, the operation time will be shorten after adding too much catalyst.
2) Mix part A and part B evenly. Otherwise the silicon rubber will be partly solidified which will make the finished molds meet a short life and waste silicon rubber.
2. Vacuum pumping
Notes: 1) This step is not have to have, but it is best if there is one. It will discharge all air in the mixture successfully, so as to ensure that there
will be no bubbles in the finished mold.
2) This step is less than 10 minutes. Otherwise, it Will cause cross-linking reaction, and no more further steps will be available.
- Pouring casting or Brush molding
Notes:1) For simple pattern products we suggest use pouring operation way, which will be very easy to operate and demould. Pourable silicone require low viscosity which will be easy to flow smoothly and easy to de-air.
2)For delicate pattern products we suggest use brushing operation way, which can copy the pattern exactly. Brushable silicone require high viscosity which won't be easy to flow away and easy to brush.
3)We suggest to set the mold for another 12 hours after demould before put it into large production.

Handing and Storage
- Precautions for safe handling:
Protective measures: Training should be provided to anyone working with or near this material. Training should cover potential health effects and proper handling techniques. Avoid contact with eyes, skin and clothing. Avoid ingestion and inhalation.
Measures to prevent fire: Ensure good local exhaust ventilation. Keep container away from any sources of ignition or heat (e.g. open flames, hot surfaces). The work area should be equipped with the corresponding species and quantity of emergency equipment, spills emergency treatment equipment and appropriate storage material.
Measures to prevent aerosol and dust generation: Ensure good local exhaust ventilation.
Measure to protect the environment: Do not allow this products to be released to the environment without proper treatment.
