silicone rubber for stone molds:
1.To add 2-4% curing agent based on the weight ratio and currently mix and use it. It has to use it up in a short time.
2.Stirring the mixed rubber material and put it into the vacuum box for 3-S minutes air extracting. The mold can be used after defoaming
3.The curing rate of this product is closely relevant to the temperature. The higher the temperature is, the greater the humidity is and the curing speed becomes faster. Users can choose the curing agent according to the weather condition,and adjust the amount of the curing agent so as to reach the appropriated curing rate.
FAQ
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:
1, Please choose the right liquid silicone according to your products.
2, Don’t use any silicone oil in mold making, because it can make the silicone mould become too soft to use.
3, 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.

1. This kind of rubber is packed in 25KG/iron drum and curing agent in 1L /plastic bottle.
2.This product should be sealed and placed in cool place so as to prevent rain and sunlight exposure.
3.The storage period of this product is half a year. If it occurs to be more viscous, stir it and reuse it with the same property. It can be reused after reinspection when it exceed the storage period.
4.The surface of the replicative mold product such as glass, ceramics, resin, wooden ware or some product with coating should be smearred with surfactants (such as detergent, shampoo, soapsuds) . Perfuse or brush the silicone rubber after the water evaporates, which facilitates demoulding.
5.This product is non-dangerous .During the operation, try to prevent any possibility of eyes and skin contact with the curing agent. Wash affected skin thoroughly with soap and water in case of touching it. Flush with clean running water immediately at least for 15 minutes, and consult a doctor if necessary.
