Description of Two Parts RTV2 Silicone Rubber for Jewellery Mold Making :
RTV2 Platinum Cured Silicone Rubber For Cake Candy Mold, 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. The silicone rubber is mainly applicable to mold duplication of poly crafts, resin craft works, lightings, candles, etc. And fabrication of precision molds.
Features of Two Parts RTV2 Silicone Rubber for Jewellery Mold Making:
- Outstanding release properties
- High Flow-ability and long working time
- Medium Hardness
- High tear resistance
- High elasticity for easy removal of complex replica parts

OTT New Material Co., Ltd. is located in Guangzhou, Guangdong. We are a leading professional manufacturer of silicone material with integrating R&D, production and sales. Our customers are from all over the world. If you are interested in our products, please feel free to contact us for further information.
1. What's silicone products you are making?
--liquid silicone, silicone rubber, silicone oil; Due to different silicone molds, our silicone has different viscosity, and cause different hardness, density to meet the requests from client.
2. Do you offer free sample to client?
--Yes, we can provide the sample for test.
3. How about the quality control in your factory?
--We have professional QC team to control the quality during production. Goods will be 100% inspected before shipment.
4. How to remove the bubbles during my mould making?
--After mixing liquid silicone with curing agent, please put the material into vacuum machine to take off the bubbles.
5. How to get good silicone mould to use longer time?
--The best way is: #A, Please choose the right liquid silicone according to your products. #B, Don't use any silicone oil in mold making, because it can make the silicone mould become too soft to use. #C, Silicone mould can be used longer after the whole silicone mould fully cured, so it's better to wait 2 hours after mould finished.
6. Why silicone rubber add curing agent after mixing a lot of bubbles?
--This is normal physical phenomena. The liquid will produce a large number of bubbles in the mixing time, so, it must pass through the vacuum exhaust bubble treatment.
