Description
Guangzhou Supplier RTV 2 liquid silicone rubber for plastic injection mould making crystal ball mould
Use-Method
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 3-5 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.

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.
We can provide liquid additional cure silicone rubber with different hardness.
1. For small size and dttailed pattern(within 30cm), 15-20 shore A can be applied, which is easy for de-molding and will not damage the patterns.
2.For the products with medium size, such as 50cm, 25-30 shore A silicone rubber should be used.
3.For products with large size, such as 1m, 35-40 shore A shall be recommend to avoid deformation.
4.If the product is large but features detailed pattern, 30 shore A silicone rubber will be workable.(It will be better to protect the products from deformation to make outer mold.)
Note: All the above products hardness should be adjusted according to customers' requirements.
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 must pass through the vacuum exhaust bubble treatment.
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.
