2.It is of sound flowability, tensile strength, tear resistance, shrink rate.
3.It doesn't have the product thickness limitation and it can be deeply cured.
4.It is of high transparency and can endure heat to 300°C-500°C. It can be used to mold epoxy resin, polyester resin, polystyrene, paraffin, large cement components, and precision mould such as metal crafts, alloy, and food mould, etc.

7.How to improve the service life of the silicone mold?
The way as follwing:
First,we make the mold should be choose a suitable hardness silicone based on product's size.
Second,silicone oil can not be added in silicone because it can make the mold become soft. As well as decrease tensile and tear strength.
Package, Storage and Attention:
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.
