silicone rubber for stone:
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.
FAQ
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.
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.

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 could be customized or adjusted according to customers' requirements.
Applications of liquid silicone rubber
Jingyi Silicone Material Co.ltd. is meanly produce: soap & candle mold silicone; RTV2 liquid silicone rubber for molding; plaster moulding gypsum decorative products mold making white silicone; medical grade skin color silicone liquid rubber for artificial human prosthesis like artifical finger; artificial penis silicone raw material rubber; 3D concrete bricks and Nordic style walll panels flexible molds; garden statues cement molding silicone; these room temperature silicon rubber are with different parameters for various materials of products, such as: polyurethane casting materials mold, high burn resistant resin products, scented stones, wax products, polyester , fimo pulp, paraffin, metal crafts, alloy, and food moulds,transparent insole, FDA food grade nipple, epoxy product, fiber rein forced platic composite products recycling vaccum bag bagging making. There are two-componet, rapid molding liquid silicone rubber, with sound property of high and low temperature resistance,these molds can achieve the unshriking effect, and non-toxic and un pungent. It is of high transpancy and can endure hear to 300℃ -500℃ for our addition high temperature silicone rubber for molding.
