Factory price RTV2 mould making liquid silicone rubber silicon for concrete stamp
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. Stirring the mixed rubber material and put it into the vacuum box for 3-5 minutes air extracting.
2.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.
Specification
1.plaster cementmould
2.For low melting alloys and pvc mould
3.For Sample mould.

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, 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.
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.
1. Why will the silicone mold be reused only for a few times?
It can be due to the following reasons:
a. Adding too much silicone oil in to silicon rubber. Silicon oil is an additive which can destroy the molecular weight of silicone rubber and reduce the tension and tear strength.
b. Using the silicon rubber with a high hardness to make molds for small sized products with delicate and intricate designs or the silicon rubber with a low hardness to makes molds for large sized products with simple designs.
(Notes: we should choose the silicon rubber specifically according to the requirements of our products to avoid this problem.)
2. Why does the silicone mold get burnt out?
This consequence happens only because you have left out the important notes when using unsatured resin materials to produce your products. The unsaturated resin products great heat when added the curing agent. So you demould the resin product within 3 minutes can avoid this problem.
3. Why is the appearance of the finished mold striate and unsmooth?
b.The product or the model has not been polished before the further operation
c. You haven't spray the release agent evenly
So when you make silicone molds, firstly you should choose a perfect mold and polish it, spray the release agent evenly on the product. In this case, the problem can be avoided.
We will make silicone products according to different requirements or samples from customers.
